| 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. Synonym: hepatitis contagiosa canis, Rubarth's disease. (05 Mar 2000) |
| infectious conjunctivitis | <ophthalmology> Inflammation of the conjunctiva of the eye that results from infection with a virus. Adenovirus is a common cause of viral conjunctivitis. Occasionally referred to as pink eye. (13 Nov 1997) |
| infectious coryza | An acute respiratory disease of chickens caused by the bacterium Haemophilus paragallinarum and characterised by nasal discharge, sneezing, and swelling of the face under the eyes; also occurs in pheasants, guinea fowl, and turkeys. (05 Mar 2000) |
| 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. (05 Mar 2000) |
| infectious granuloma | Any granulomatous lesion known to be caused by a living agent; e.g., bacteria, fungi, helminths. (05 Mar 2000) |
| infectious hepatitis | <virology> A form of viral hepatitis, known as infectious hepatitis, due to its ability to be spread through personal contact with oral secretions or stool. Virus will be shed in the stools of an infected individual 2-3 weeks prior to the onset of any symptoms. Hepatitis A may also be transmitted sexually. Symptoms are similar to those of influenza, but the skin and eyes may become yellow. Recent travel to a third world country is a risk factor. There is no specific treatment but infected individuals should avoid potentially hepatotoxic substances. The virus is a small (27nm diameter) single stranded RNA virus with some resemblance to enteroviruses such as polio. (27 Sep 1997) |
| infectious hepatitis immunization | See Immunization, hepatitis a. (12 Dec 1998) |
| 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 icterus | A severe form of leptospirosis caused by leptospira interrogans serogroup icterohaemorrhagica and transmitted to man by the rat. (12 Dec 1998) |
| infectious jaundice | Sometimes used in referring to viral hepatitis type A. See: Weil's disease (05 Mar 2000) |
