positive" exposure to vesivirus was used, allowing samples with a slightly lower level of antibody to be included as positive, it showed that 81 percent of abortion-associated mares in the study group were seropositive for vesivirus exposure, the scientists said.
In a second study involving experimental exposure of pregnant mares to Eastern tent caterpillars where 17 of 29 aborted, the association of vesivirus antibodies with abortion problems appeared to be stronger than the association with Eastern tent caterpillars, the scientists said.
The most common point source of infection with vesivirus, the study said, would be animals with acute or chronic infections with persistent shedding of virus. Transmission via direct contact has been often reported in other animal species, such as swine, cattle and reptiles.
There is no vaccine or medical treatment for vesivirus control in horses, the researchers said, so vesiviral problems that are identified through accurate diagnosis would probably be managed by those methods used for any infectious disease, such as animal quarantines and other herd management techniques.
