| infectious bovine keratitis | A highly contagious keratoconjunctivitis that occurs in range or pastured cattle during the summer months, is transmitted most commonly by contact with infectious discharges, and is caused by Moraxella bovis. (05 Mar 2000) |
|---|---|
| infectious bovine keratoconjunctivitis | A disease of cattle caused by the bacterium Moraxella bovis and characterised by blepharospasm, conjunctivitis, lacrimation, and corneal opacity and ulceration. Synonym: infectious ophthalmia, pinkeye. (05 Mar 2000) |
| infectious bovine rhinotracheitis | A herpes virus infection of cattle characterised by inflammation and necrosis of the mucous membranes of the upper respiratory tract. (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 bulbar paralysis | A highly contagious herpes virus infection affecting the central nervous system of swine, cattle, dogs, cats, rats, and other animals. (12 Dec 1998) |
| infectious bursal disease | A highly contagious acute disease of chickens caused by the infectious bursal disease virus and characterised by whitish diarrhoea, dehydration, prostration, and destruction of the bursa of Fabricius, compromising the bird's immune system. Synonym: Gumboro disease. (05 Mar 2000) |
| 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 canine hepatitis | A disease of dogs, caused by canine adenovirus 1, and characterised by fever, depression, loss of appetite, vomiting, bloody diarrhoea, petechial haemorrhages in the gums, pale mucous membranes, and jaundice.

| infectious disease | A disease resulting from the presence and activity of a microbial agent. (05 Mar 2000) |
| 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 eczematoid dermatitis | An inflammatory reaction of skin adjacent to the site of a pyogenic infection; e.g., purulent otitis, the area around a colostomy, or intranasal infection; thought to be due to a local sensitization to the resident organisms. (05 Mar 2000) |
| infectious enterohepatitis | A disease chiefly affecting turkeys, caused by Histomonas meleagridis and characterised by ulcerative and necrotic lesions of the liver and caecum, acute onset, and a high mortality rate. It is transmitted inside the eggs of the nematode Heterakis gallinae, which is primarily responsible for maintaining and spreading the infection. Synonym: blackhead, infectious enterohepatitis.
