| vesicular exanthema | An extinct disease of swine caused by vesicular exanthema virus of swine, a member of the family Caliciviridae; it closely resembled foot-and-mouth disease and, in swine, was characterised by fever, loss of weight, and vesicles on the snout, tongue, and feet. (05 Mar 2000) |

| gonadotropins, equine | Polypeptide hormones secreted in pregnant mares at the junction of the placenta and endometrial cups.

| rhinoviruses, equine | A group of viruses of the family picornaviridae, yet unclassified as to genus, though not a member of rhinovirus. They cause a disease in horses characterised by rhinitis, pharyngitis, and fever. (12 Dec 1998) |
| western equine encephalomyelitis | An equine encephalomyelitis found in the western U.S. And parts of South America, transmitted by mosquitoes and caused by the western equine encephalomyelitis virus (a species of Alphavirus in the family Togaviridae); the infection is similar to but milder than eastern equine encephalomyelitis in man and is, as a rule, inapparent, but some cases with central nervous system involvement have been fatal. (05 Mar 2000) |
| strongyle infections, equine | Infection of horses with parasitic nematodes of the superfamily strongyloidea. Characteristics include the development of haemorrhagic nodules on the abdominal peritoneum. (12 Dec 1998) |
| eastern equine encephalomyelitis | A form of mosquito-borne equine encephalomyelitis seen in the eastern U.S. And caused by the eastern equine encephalomyelitis virus, a species of Alphavirus, which belongs to the family Togaviridae; initial fever and viraemia are followed by signs of central nervous system involvement (excitement, then somnolence, paralysis, and death); the incidence of clinical infection in man is low but case fatality may be high. (05 Mar 2000) |
| encephalomyelitis, equine | An alphavirus infection of horses and mules, communicable to humans, occurring in the united states and parts of central and south america. (12 Dec 1998) |
