The mucosal surfaces are important sites of entry for a majority of pathogens, and viruses in particular. 12 and became ill 10 days later. Infection is by aerosol and nasal secretions transmission and this can occur even if there is a maternal antibody present in the body. We hypothesized that inoculation of EHV 5 isolated from cases of EMPF into the lungs of clinically normal horses would induce lung fibrosis similar to EMPF. owned by that person or in the possession, control or charge of that person; on land owned and occupied by that person; or dealt with by that person as a veterinary practitioner, an inspector under the Meat Industry Act 1993 or the Export Control Act 1982, operator of a meat processing facility licensed under the Meat Industry Act 1993 where a quality assurance program is in force, the owner or person in charge of premises registered as a veterinary diagnostic laboratory, knacker, stock agent or other person dealing with livestock, livestock products or hives by way of a profession, trade or business, must report the disease.

In response to outbreaks of the disease in recent years, the United State Equestrian Federation adopted a new vaccination rule.

EHV-1 swells the blood vessels in the brain, leading to symptoms somewhat similar to those that accompany bovine spongiform encephalopathy, or mad cow disease. Nested PCR for envelope glycoproteins in nasal swab can be used and this is more sensitive than virus isolation. The bad news is “there’s not a vaccine that will protect against this aberrant form of the virus,” King said. Horses with EHV-1 “get really unsteady on their hind legs,” said Marla Foreman, an equine veterinarian in Pasco, Wash. I., Cordy, D.
