    We've been hearing that there have been EVH-1 outbreaks at Pimlico, Laurel & Charlestown (WV). What's the word on this?

    Apparently, the Middleburg Training Center is closed to horses coming in from Maryland and possibly WV as well, but that status seems a bit questionable.

    Any info would be appreciated.

    Looks like other tracks have joined the ranks of restricting entries from Pimlico. Also putting Pimlico on quarantine

    Doubtful anyone would want horses from any MD track... or training facility or farm that conducts work & go-s, or any horse that has run here recently.
    This has shown to be a strain w/ neurological attacks only and the vaccines are pretty much useless. Your modified lives have a slightly better result w/ this strain if used BEFORE an outbreak w/ exposure. As well, a horse sheds the virus well before showing outward signs.
    Really, your best shot is checking your horse's temp twice daily, establishing a norm for each animal so should he/she spike (and you happen to notice) begin treatment for this virus ASAP. Meanwhile, you've drawn blood & sent it directly to the lab and can decide on continuing treatment pending your animal's titer level (low, boarderline, high). Regular temp checks will not prevent your horse from getting ill but will definately ten-fold his odds of recovery through rapid response.
    Updates include a pony/outrider horse testing positive from Laurel today and a horse at Penn Nat. (who ran here recently) falling ill prior.
    You might note test results on different horses can vary and not always match the reality of a condition! So keep your eye on the temps and any unsteadyness in your horses.

    Right now Penn, Philly, all MD tracks and Ct are on restrictions for outside horses. Here at MNR they are not letting in horses from PA, MD and KY. The restriction for CT went into effect at 1pm on sunday. MNR is thinking about clsoing to all outside horses. Meaning only horses stabled at MNR will be allowed to race. The commission was supposed to be having a meeting today about it.

    Another Horse Stabled in Maryland Positive for EHV
    by The Associated Press
    Date Posted: 1/24/2006 5:21:04 PM
    Last Updated: 1/24/2006 5:45:53 PM


    A horse at Laurel Park has tested positive for the equine herpesvirus that has already claimed two horses at nearby Pimlico Race Course and prompted a state quarantine at the home of the Preakness Stakes (gr. I).
    However, the Laurel horse has not shown any symptoms of the disease and it is not clear whether the horse is contagious, or merely has been exposed to the virus in the past like many other horses, said Guy Hohenhaus, state veterinarian for the Maryland Department of Agriculture.

    The horse, an outrider used in training race horses, has been brought to Pimlico for isolation and further testing. The tests will most likely be in the form of nasal swabs that will be cultured to see if the virus is present in the respiratory tract as well as in the bloodstream.

    If the swabs test positive, "then that horse probably needs to be restricted until it tests negative," Hohenhaus said.

    The disease, which does not affect humans, can cause upper respiratory infections in horses as well as neurological symptoms that may affect the ability to walk and run. At least 11 horses at Pimlico have shown signs of the virus this month and two horses have been euthanized.

    Isolation at Pimlico is expected to continue at least until the middle of next month. Hohenhaus said state animal officials are looking for a three-week disease free period before they are comfortable that the outbreak has passed.

    "We're looking for an exit, at what point in time do we declare this over," Hohenhaus said.

    The first barn could be released from the quarantine order as early as next week and "the earliest we could be out of this is mid-February," the state veterinarian said.

    The Pimlico racing season begins in mid-April and includes the Preakness, the second leg of the Triple Crown, in May. The racing secretary for the Maryland Jockey Club, Georganne Hale, said the virus might affect racing dates.

    Horses that race at Laurel are drawn from a pool of about 2,000 horses statewide, including about 500 at Pimlico, as well as horses from other states. The Pimlico horses are now unavailable to race at Laurel and some states are not allowing horses to travel to Maryland, limiting the number of horses available to race at Laurel.

    David Zipf, a veterinarian for the Maryland Racing Commission, said the virus is normally not very contagious, but the strain or strains that have hit Pimlico appear to be more easily spread and more virulent.

    One horse that tested positive at Pimlico, for example, was in a barn at the opposite end of the race course from the others.

    "We can't explain that and this is what makes it a scary situation," Zipf said.

    Why the outbreaks are occurring now is still a mystery, Hohenhaus said.

    "There's no smoking gun or leading theory coming out about what might have triggered this," Hohenhaus said.

    Just got word from a trainer at Philly that they are going to quarantine the track there for 3 weeks. Haven't heard if this is related to what is happening in MD.

    Neurologic Equine Herpesvirus Q&A
    by: Stephanie L. Church, News Editor
    January 2006 Article # 6468


    It isn't just our imagination--we have been hearing about more neurologic equine herpesvirus outbreaks in the past several years than we were aware of previously. The current outbreaks in Kentucky and Maryland bring the disease back to the forefront, and there are many questions that horse owners, trainers, and even veterinarians have about the illness in its current state.

    The University of Kentucky's Gluck Equine Research Center has the only Office International des Epizooties (OIE, or World Organization for Animal Health) reference laboratory for equine herpesvirus in the Western hemisphere. Thus, samples from most of the outbreaks are sent here so George Allen, PhD, professor in veterinary science at Gluck and head of that laboratory, can type these viruses and know which strains are circulating. Yesterday (Jan. 10) The Horse interviewed Allen, David Powell, BVSc, FRCVS, professor in veterinary science, and Peter Timoney, FRCVS, PhD head of the Gluck Center, on the basics of neurologic EHV-1, characteristics of the current outbreaks, and what we've learned about preventing the illness and controlling its spread.


    --------------------------------------------------------------------------------

    Q: With all of the different herpesvirus outbreaks over the past few years, there is a lot of confusion and fear among horse owners because they don't understand it. What would you like horse owners to understand and what do you think the horse owning population needs to know about herpesvirus in general and neurologic herpesvirus?

    A: Allen--I think the most significant thing is there seems to be an increase in the occurrence of disease caused by these neuropathogenic strains of herpesvirus. This particular disease is one that's especially of concern because it has the potential for causing devastating outbreaks and for shutting down much of the industry, especially the racing industry.

    Powell-- It's only within recent years that it seems there's been an increase in the incidence of this neurological form, which came into prominence with the outbreak in northern Ohio at the beginning of 2003. Since then, we've identified outbreaks of this neurological form occurring throughout the United States in different breeds and in different areas. In 2003, we examined material from five different outbreaks in five states (the initial outbreak in Ohio at Findlay University, cases in Kentucky at Turfway, Virginia, Oregon, and a racetrack in Pennsylvania) of the neurological, whereas in 2004 we saw just one or two (Maryland and Michigan). We saw in 2005 an increase--six outbreaks reported in Kentucky, Maryland, Michigan, Pennsylvania, and New York.

    I think it's also interesting to observe that overseas, there's been an apparent increase in the incidence of this particular manifestation, particularly in Europe. England is where it has been primarily reported in Europe.

    Allen--Previous to 2003, the most number of outbreaks that we were aware of in all those preceding years was on average one outbreak per year.


    --------------------------------------------------------------------------------

    Q: Are the current outbreaks at Turfway, in Henderson, and at Pimlico caused by a strain that is distinctly different from others seen recently (as in Findlay, Churchill, Maryland, Pennsylvania, and others)? Or all they all the same thing?

    A: Allen--All isolates of EHV-1 recovered from neurologic outbreaks share a common mutation, so they're the same genetic strain, but different from the strains of EHV-1 that cause only respiratory disease and abortion. There are other minor strain differences (between EHV-1 isolates), but none of those are associated with any known difference in clinical disease except for the specific ones that we've discovered and talked about (the neurologic strains).


    --------------------------------------------------------------------------------

    Q: When does this mutation happen? Is it a regular herpesvirus, per se, that gets into the horse and mutates there, then the horse spreads it as a mutated virus, or did the virus mutate once and that mutated strain is what's spreading?

    A: Allen--That's the question we wish we knew we had the answers to, but you just identified the two possibilities, either there's a reservoir of horses that carry this mutant herpesvirus and that latent virus is periodically reactivating and spreading to other horses, or it may be that each new outbreak of this disease is a result of an independent and new mutation event. And we just don't know the answer to that. A mutation of the wild type regular strain into the paralytic strain, that mutation event may be occurring in multiple cases--each case giving rise to another outbreak.


    --------------------------------------------------------------------------------

    Q: It has been said that these horses have higher titers of EHV in their blood than in past outbreaks. Are you finding this in all herpes cases or just specific outbreaks? What do these higher titers mean?

    A: Allen--The higher titers is referring to the viral load that's present in the circulating blood of these horses--it's called viremia--it's virus that's present within the lymphocytes (white blood cells) of the horse. It's those lymphocytes that carry the virus to the central nervous system. So, horses that are infected with these neuropathogenic strains have higher numbers of virus-containing lymphocytes that are constantly bombarding the central nervous system, so there's an increased risk of infection of the CNS because of that.

    Timoney--There are three characteristics of the response of the horse to these neuropathogenic strains. (The viremia) occurs earlier, it reaches a higher peak, and it lasts longer (he refers to a figure that ran with an update in Equine Disease Quarterly).


    --------------------------------------------------------------------------------

    Q: Please describe the clinical signs in the current outbreaks.

    A: Powell--The initial feature is the animal developing quite a high fever, and one of the new features of this manifestation is that they very quickly become ataxic (incoordinated) or paralyzed in the hind legs, usually they display incontinence, and the feature is the very rapid progression of the disease to the extent that a number of animals have become recumbent and unfortunately have been euthanized within two, three, or four days. And this is something that hasn't been observed before--the progression of the disease has previously been much slower than that.


    --------------------------------------------------------------------------------

    Q: When you say previously, does that mean before the 2003 outbreaks, or before the current ones?

    A: Powell--I would say that prior to the Findlay outbreak, there was a pattern of disease that was somewhat different, and subsequent to the Findlay outbreak we've seen a much more rapid progression of clinical signs in the horses.


    --------------------------------------------------------------------------------

    Q: What is the incubation period of the illness in the current outbreaks?

    A: Allen--It's during that febrile phase that the horse is most infectious, most contagious, to others. And then, anywhere from six to 12 days later is when the neurologic signs set in.


    --------------------------------------------------------------------------------

    Q: Are these horses displaying respiratory signs?

    A: Allen--The majority of the horses that get this don't show any respiratory signs, and those that do show only a mild nasal discharge.

    Powell--One might add that in situations where pregnant mares have been exposed, those mares have usually aborted.


    --------------------------------------------------------------------------------

    Q: It has been said that the virus can spread 35 feet in the air. Where did that figure come from, and is it possible that in the outbreaks we've seen recently, that it can spread farther?

    A: Allen--I don't know where that figure came from either. We do know that it gets spread from one end of the barn to the other end in quite a rapid time period. Part of that spread is from horse-to-horse-to-horse, it just runs down that aisle of stalls.


    --------------------------------------------------------------------------------

    Q: Does it spread this way through touching noses, or from picking up the virus particles in the air?

    A: Allen--It can be either of those. Primarily it's airborne infection.

    Timoney--Clearly there is a potential for aerosol transmission, i.e. infective viral particles are in the air that's exhaled by an infected horse and then inhaled by a susceptible animal. However, within barns, there's always the potential for horse handlers to transfer the infection by indirect means. They may come along and put a shank on a horse…they don't give a second thought if the horse looks normal…there may be a total absence of any respiratory signs. Then they'll go down the stall row and handle some other horses. It's part of their daily routine. You can't exclude or say definitively that contagion couldn't be transmitted indirectly through a person's hands or other objects, if they put their hands around the nostril area of an asymptomatically infected horse and then proceed and handle other healthy horses.


    --------------------------------------------------------------------------------

    Q: What are your vaccination recommendations when EHV is detected at a facility?

    A: Allen--You are asking all the hard ones that there are no hard answers to.

    Powell--As far as the respiratory and the abortion form of the disease in concern, we think vaccination is very helpful, although it certainly doesn't prevent individual animals from succumbing to cases of abortion.

    As far as policy on vaccination for the neurological form of the disease, historically it was recommended that during an outbreak it was unwise to vaccinate the in-contact animals because some thought that there might be an immune-stimulated/mediated reaction. But I think the most recent work that Dr. Allen has undertaken indicates that might not be the case and that we're dealing with some more virulent strain of the virus. So I think in terms of neurological form of the disease, we may have to rethink our philosophy on vaccination, but because of the rapidity of the disease in terms of the manifestation of clinical signs, it's unlikely that vaccination of immediate animals in contact is going to have any great benefit, and as it has already been said, the virus is probably spread to those animals within a relatively short period of time. So, I think the bottom line is in the context of these neurological cases, we may have to rethink our philosophy on vaccination and how we approach the problem, in terms of whether we're looking to develop new vaccines or whether we change the routine.

    Timoney--Getting to the core of it, there has been one report that would suggest that the modified live virus vaccine against herpes 1 has some efficacy against the neurologic form of the disease.

    Allen--What that study really showed was that the vaccine was efficacious in minimizing the non-neurological clinical signs-- fever and virus shedding--but it was not a study that provided firm evidence that the vaccine prevented the neurological manifestations. In fact, in our own studies here recently, we found that the horses that are most likely to develop the neurologic signs following EHV-1 infection are those that show no fever at all. So that study, in my view, is not as strong in making the claim for vaccine efficacy against EHV-1 neurological disease as those investigators have stated.

    In terms of preventing infection, I think vaccination is still a recommended activity. But in terms of vaccinating already exposed horses, it's still an open question.


    --------------------------------------------------------------------------------

    Q: What is the length of quarantine you recommend? Is it still the 21 days after the last fever resolves?

    A: Allen--As far as I know that's still the quarantine that the state veterinarian's office is sticking to and they found it to be effective.


    --------------------------------------------------------------------------------

    Q: People have said horses are being moved off the grounds at Turfway in the barns that aren't under quarantine. How do we know that one or more of these healthy-appearing horses isn't carrying the virus back to naïve horses at home?

    A: Allen--I would say that it's essential for the racing industry to be able to move their horses and if movement is curtailed, then racing is going to be shut down. So there has to be some happy medium of restricting movement in those horses that are likely to have been exposed vs. those that are not so likely to have been exposed. But there's still the chance that there may be one or two in that latter group that has been exposed, but that's one of the risks that has to be taken to keep the racing going.

    Powell--The risks can be mitigated by checking the horses before they are moved, particularly the temperature records. I think in the outbreaks that have occurred, this has been a very effective tool for identifying possible animals--it's not perfect (fever might persist only for a short period and can be missed even if temperatures are taken every 24 hours), but it's an excellent and very simple tool to apply without having to resort to any laboratory procedures. I think it is a simple procedure that only takes a short period of time, and it can be done by any personnel at the farm or at the racetrack.

    Timoney--If we completely close down movement, you're essentially going to undermine confidence in the industry and it will likely result in significant economic loss. What the state veterinarian is doing is essentially carrying out risk assessment and trying to mitigate the risk factors and yet allow for controlled movement to occur. You can't have a zero risk situation. Through the work that Dr. Allen and others have done, we know that this particular group of viruses has the ability to establish latency in a very high percentage of exposed and infected animals, so there is a carrier reservoir out there. It's analogous to herpes simplex virus infection in man. What do you do? Do you restrict every one that develops cold sores from consorting with those that are not affected?

    We must bear in mind that a lot of these procedures have been implemented in the past, namely the period of quarantine or restricted movement. They've been found to work in curtailing spread of the disease. There is a historical background that we can draw upon and say, "Look, we're not plucking intervals of times or procedures out of thin air."


    --------------------------------------------------------------------------------

    Q: Why are these outbreaks seemingly spotty, they disappear, and then they pop up again? What can we learn from this in preventing outbreaks?

    A: Timoney--You could ask that question of many, many infectious diseases. We don't know when they're likely to occur, all we do know is they will recur, and our ardent hope is that we minimize the number of animals that express clinical signs of whatever disease it is, whether its respiratory disease , whether it's abortion, whether it's whatever. But we're not at a point where we can say with any degree of certainty or assurance that we're not going to continue to see sporadic occurrences and outbreaks of this or other diseases. Hopefully, any such outbreaks will involve minimal numbers of clinically affected animals.

    Allen--One factor that's probably involved is stress. It's been shown that astronauts that go into orbit almost invariably show serologic evidence of reactivation of latent herpesviruses. Any stress situations could be a factor in those spotty episodes that are seen and I think minimalization of stress should be one of the management goals. Again, stress is part of the activities of a horse's life--a performing horse or a breeding horse.


    --------------------------------------------------------------------------------

    Q: Currently, how long does it take for a diagnostic test to come back?

    A: Allen--If you send it to me, it takes three days. If you send it to the diagnostic lab, they have a 24-hour turnaround time.


    --------------------------------------------------------------------------------

    Q: I understand there might be a need for a high-speed PCR. Do you think that is something the diagnostic center should have?

    A: Allen--Yes, a high-thoroughput (PCR)


    --------------------------------------------------------------------------------

    Q: What other entities can test for EHV?

    A: Allen--Most state animal disease labs have the capability to test for EHV.


    --------------------------------------------------------------------------------

    Q: Any closing remarks?

    A: Timoney--People need to realize that the neurologic form of this disease has existed and has occurred for a significant number of years, long before the Findlay occurrence, and in some instances with major economic consequences for the industry…not just in North America, but in Western Europe. What we're talking about here as a clinical pathologic syndrome is not unique. What Dr. Allen and his colleague (researcher Nick Davis-Poynter, PhD, head of infectious diseases at the Animal Health Trust in England) have been able to demonstrate is there is a scientific basis (the mutation) for the behavior of equine herpesvirus in situations where it's associated with neurologic disease, which is a terrific advance.

    Powell--From a research point of view, (the current state of equine herpesvirus) emphasizes how important it is to be studying a problem over a long term and not suddenly jumping from one situation to the next. Dr. Allen has spent his career (25 years) working on equine herpesvirus and following the manifestations of the virus in its genetic and clinical sense. A great deal of what we know now and some of this new information would not necessarily have arisen unless that long-term commitment to research on the problem had been undertaken.

    Not to lighten the seriousness of this issue, but this made me chuckle. I ride at the Bowie Training Facility in MD. Last week our trainer was torn whether or not to run. I ride a string of about ten everyday.We have about 35 in the barn. One of them is a nice colt going into his second race. I really wanted to see how he ran but didn't want to risk his health of course. So he ran...didn't finish great. Today was his first day back in training. Every groom takes temps before horses train. My groom throws me up and says " Not sure if the boss wants to train his temp is 104." So I call the boss and dismount. We put him back and start thinking about where to isolate him. Turns out the groom...who is spanish wasn't very clear in his speech and the colt's temp was only 100.4! PHEW! You should have seen us. We have tried to do everything to prevent the spread of the disease which isn't even at our facility. Can never be too careful. This definitely made me chuckle this morning.

    Ack, the horse from barn A was put down today. I have mixed feelings on that call, which I'll not share (& are just my own thoughts), just giving an update. All the others are doing very well http://chronicleforums.com/groupee_c...icon_smile.gif

    BloodHorse 1/26/06 - "Another Horse Euthanized at Pimlico; Laurel Park Cancels Two Racing Cards"

    Another horse has been euthanized at Laurel Park after testing positive for equine herpesvirus (EHV-1). A private veterinarian of trainer Joe Delozier euthanized General Strike Jan. 25. The 3-year-old showed no signs of improvement after testing positive for the virus Jan. 19.

    Since Jan. 1, 11 horses have tested positive for the virus causing the Maryland Jockey Club to place Pimlico Race Course under quarantine Jan. 21. Three horses have been euthanized, while eight horses from Barns 5 and 6 are currently in isolation in the Detention Barn.

    In connection to the virus, officials at the MJC have decided not to card live racing Jan. 29 and Feb. 5. Laurel will continue to race four days a week, on a Wednesday through Saturday schedule.

    A shortage of entries, stemming from a quarantine of 500 horses at Pimlico and restrictions on the movement of Thoroughbreds in and out of the state due to EHV-1, led to the scheduling to decision by chief operating officer Lou Raffetto after discussions with Maryland Thoroughbred Horsemen's Association president Richard Hoffberger.

    "We are working with a limited pool of horses and it has taken its toll on our entries," Raffetto said. "Cutting back to four days a week the next two weeks will allow us to have the quality and quantity we were accustomed to before the outbreak of the virus."

    Since the restrictions began Jan. 6, the average field size has been 7.3 per race. In 21 live days in December, Laurel averaged 8.6 starters per race.

    Races from Jan. 29 will be used as extras for Feb. 1. The races in the condition book for Feb. 5 will be used as extras for Feb. 3-4.

    Equine herpesvirus causes upper respiratory infections in horses and is also known to cause neurological disease. There is currently no known method to reliably prevent the neurologic form of EHV-1. It is recommended to maintain appropriate vaccination procedures in an attempt to reduce the incidence of the respirator for of EHV-1, which may help prevent the neurologic form.

    Hold Ordered on Maryland Farm for Suspected EHV-1 Cases
    Date Posted: 1/26/2006 8:11:50 PM
    Last Updated: 1/26/2006 10:58:17 PM

    (from Maryland Jockey Club release)
    Suspected cases of equine herpesvirus (EHV-1) caused the Maryland State Veterinarian to place an "Investigational Animal Hold Order" Jan. 26 on a private farm in Kent County.
    The farm is used as an off-track training facility for a Pimlico-based trainer, but the state veterinarian office said it would not identify the farm or its location.

    The farm received a horse from Pimlico on Jan. 10 before track officials closed movement to and from the facility. The Maryland Department of Agriculture is waiting for test results, which are expected next week, to determine the cause of illness for one horse euthanized Jan. 26 and another showing neurologic signs.

    "This new occurrence is extremely unfortunate and we are working closely with everyone involved and using the best science available in the equine research community to prevent any possible spread of illness," said Guy Hohenhaus, Maryland state veterinarian. "It is believed that this incident is not a distinctly new case. We encourage horse owners with concerns to contact their private veterinarian to determine if a vaccination or booster is recommended for their horses at this time."

    Updates will be posted daily on the MDA Web site.

    Apparantly there is a new vaccine:

    A new drug by Pfizer has been created to protect against EHV-1. "I would recommend that healthy horses about to be shipped or exposed to unknown horses get vaccinated with Rhinomune," said Holland. "This vaccine contains a modified live EHV-1 virus that triggers a very effective immune response."

    In a limited study by a professor of equine virology at Cornell, horses were vaccinated against EHV-1 and then exposed to a strain of the virus retrieved from a deadly 2003 outbreak at the University of Findlay in Ohio. Horses vaccinated against EHV-1 using the modified live vaccine Rhinomune consistently had lower fevers, no neurological disorders, and shed less virus in their nasal fluids compared to those vaccinated with an inactivated vaccine, which employs a killed virus to activate an immune response.

    As luck would have it - or not - we sent a string of horses to Maryland for the winter. They're stabled and trained at Bowie, but now I'm spooked about going to Laurel to run. The races aren't filling and, while it's a great opportunity to run in small fields, at what risk? My one and only horse is there too.

    This winter has really turned out to be a bust! Sal had intended to run at Penn, Charlestown, Philly and Laurel and now, of course, he's quarantined. I just want the powers that be to do whatever they have to do to get this under control...fast!

    I was going to run last Sunday at Laurel before they decided to shut the track down at Pimlico. Then it became a moot point, but I will share my plan anyway.
    1. Ship the horse myself, with no other horse in the trailer.
    2. No pony, if you have been reading between the lines, you would know that this is probably the most important points of my plan.
    3. I bought several cans of lysol and clorox disinfecting spray and had planned to go nuts on the stall several minutes before unloading the horse in the receiving barn. Paying special attention to stall fronts on both sides as that is where horse like to hang out and tend to bite at the wood there.
    4. Make sure the groom flips the lip for the horse ID man as opposed to letting him touch her mouth.
    5. Carry hand sanitizer in my pocket and use liberally.
    6. Don't use the wash rack in the test barn if we got so lucky as to go there. Clean the horse off with my own bucket and sponge outside of the receiving barn once we got back there.

    Obviously I never got to implement my plan, but I really think that I reduced the risk to near zero. I was the fave in the form in a msw with a first timer that I bought for a dollar. I tell you, I wanted to cry when it went off as a three horse field.

    1. The horse received from Pimlico into Kent County was previously a Fla ship-in who was stabled at PIMLICO (barn A at *Pimlico*) until recently.

    2. Sanitizing your horse for a run at Laurel is fine but guess you'd have to have it break from the starting gate all alone w/ a personal gate guy as well. And stay the heck out of receiving barn and out of breathing room/spray of pack you're running in company with. Having allowed a horse to run from barn where FIRST horse was euthanised just a couple of days after was a compromise, as well as continueing to ship everyone at Pimlico on both sides together not helping. But who kows how many were exposed before anyone ever showed signs at all, eh?

    3. Horses at Bowie are running with horses at Laurel who are running w/ out-of-state horses (like Penn Nat) who are in turn allowed to ship into Bowie. Just received a couple new horses at Bowie from Penn Nat. As well, horses from across the street (& off grounds) at Charlestown have been, for the most part, shut out of CT racing & are shipping into new training/running facilities on MD tracks.

    4. Health Certs should be the main doc required before transporting anywhere....not because it certifies anything about a horses health but it allows a horse to be tracked by leaving a good paper trail. We must provide/receive coggins but that's all when entering grounds.

    5. Rummors today of a horse from another barn having herpes stems from a horse that started his symptoms after flipping over while being treated for a lameness issue. He was tested for herpes but pretty sure that's not what caused his neurological signs which appeared right after flipping & why he was put down.

    Modified lives only have a slightly better result % w/ neurological form, but it's what I use on our ponys.

    Personally, I'm terrified of avian flu right now. Seriously...one trip to CDC or WHO website will do it for most.

    i just read a news article in today's paper that said the florida horse was a carrier of the virus - i wonder about the other horses on the transport truck - or ones that got on the truck since that horse got off - wouldn't that also be a concern? doesn't the virus live for a couple of days on equipment and other objects?

"This vaccine contains a modified live EHV-1 virus that triggers a very effective immune response."

    In a limited study by a professor of equine virology at Cornell, horses were vaccinated against EHV-1 and then exposed to a strain of the virus retrieved from a deadly 2003 outbreak at the University of Findlay in Ohio. Horses vaccinated against EHV-1 using the modified live vaccine Rhinomune consistently had lower fevers, no neurological disorders, and shed less virus in their nasal fluids compared to those vaccinated with an inactivated vaccine, which employs a killed virus to activate an immune response.
    Rhinomune is not new, I have been using it for years. Of course, you can't use it in pregnant mares or young foals but we vaccinate all mares as soon as is prudent after foaling with the rhinomune and foals once they are of age. Pregnant mares get the usual. Not much you can do other than hope once they've been exposed.

    It looks like they are going to lift the quarantine at Pimlico on the 4th if all goes well. I am surprised to an extent that they are doing it that quickly, but I talked it over with my vet and he was ok with it. I guess I will do with his opinion then.
    I am entering two of my three for Saturday if we get the go ahead. Could be a busy day. Let's pray this nightmare really is over and remember those who were lost.
