| infectious arteritis virus of horses | <virology> A virus of the genus Pestivirus, a member of the family Togaviridae, that causes equine viral arteritis. It is probably the most common cause of equine influenza and an important equine respiratory disease frequently causing abortion, pneumonia, or other infections. Synonym: infectious arteritis virus of horses. (05 Mar 2000) |

| biliary fever of horses | <veterinary> A disease of horses caused by species of Babesia and characterised by high fever, icterus, and enlargement of the spleen and lymph nodes. Synonym: biliary fever of horses, equine biliary fever. (05 Mar 2000) |

| horses | Large, hoofed mammals of the family equidae. Horses are active day and night with most of the day spent seeking and consuming food. Feeding peaks occur in the early morning and late afternoon, and there are several daily periods of rest. (12 Dec 1998) |
| arteritis virus | A genus that is currently unclassified, arterivirus is likely to be part of coronaviridae or a new family. It was previously classified under togaviridae. The type species is arteritis virus, equine. (12 Dec 1998) |
| equine arteritis virus | <virology> A virus of the genus Pestivirus, a member of the family Togaviridae, that causes equine viral arteritis. It is probably the most common cause of equine influenza and an important equine respiratory disease frequently causing abortion, pneumonia, or other infections. Synonym: infectious arteritis virus of horses. (05 Mar 2000) |
| avian infectious laryngotracheitis virus | <virology> A herpesvirus causing avian infectious laryngotracheitis. (05 Mar 2000) |
| infectious anaemia virus, equine | A species of lentivirus, subgenus equine lentiviruses (lentiviruses, equine), causing acute and chronic infection in horses. It is transmitted mechanically by biting flies, mosquitoes, and midges, and iatrogenically through unsterilised equipment. Chronic infection often consists of acute episodes with remissions. (12 Dec 1998) |
| infectious bovine rhinotracheitis virus | A herpesvirus causing infectious bovine rhinotracheitis. Synonym: IBR virus. (05 Mar 2000) |
| infectious bronchitis virus | An RNA virus of the family Coronaviridae and the type species of the genus Coronavirus, causing infectious avian bronchitis, being most pathogenic in chicks up to about 4 weeks of age; not to be confused with avian infectious laryngotracheitis virus. (05 Mar 2000) |
| infectious bronchitis virus, avian | A species of coronavirus causing infections in chickens and possibly pheasants. Chicks up to 4 weeks old are the most severely affected. (12 Dec 1998) |
| infectious bursal disease virus | A species of avibirnavirus causing severe inflammation of the bursa of fabricius in chickens and other fowl. Transmission is thought to be through contaminated feed or water. Vaccines have been used with varying degrees of success. (12 Dec 1998) |
| infectious ectromelia virus | A virus belonging to the family Poxviridae morphologically similar to vaccinia virus, which occurs as a latent infection in laboratory mice, but which may be activated by stresses such as irradiation and transport to cause disease; inoculation into the footpad results in oedema and necrosis. Synonym: ectromelia virus, mousepox virus, pseudolymphocytic choriomeningitis virus. (05 Mar 2000) |
| infectious hepatitis virus | <virology> An RNA virus (hepatovirus) in the family Picornaviridae, that is the causative agent of viral hepatitis type A. The virus replicates in hepatocytes and is presumed to reach the intestine via the bile duct. Transmission occurs by the faecal-oral route. Synonym: infectious hepatitis virus. (20 Sep 2002) |
| infectious pancreatic necrosis virus | The type species of aquabirnavirus, causing infectious pancreatic necrosis in salmonid fish and other freshwater and marine animals including mollusks. (12 Dec 1998) |
| infectious papilloma virus | <virology> A disease caused by the human papilloma virus characterised by a soft wart-like growth on the genitalia (for example penis, vulva). In adults this infection is most commonly transmitted sexually. Genital warts are very common and are increasing in incidence. Safe sex practices, such as using condoms can help decrease the risk of infection. Treatment includes several topical agents to eradicate the lesions, cryosurgery, laser therapy, electrocauterisation or surgical removal. See: alternate name condyloma acuminata. Acronym: HPV (27 Sep 1997) |
| infectious peritonitis virus, feline | A species of coronavirus infecting cats of all ages and commonly found in catteries and zoos. Cats are often found carrying the virus but only a small proportion develop disease. (12 Dec 1998) |
