tuberculosis

applied generally to diseases caused by tuberculous group of bacteria in the genus Mycobacteria, which includes Mycobacteria tuberculosis, M. bovis and M. avium. See also fish tuberculosis, mycobacteriosis.

atypical mycobacterial tuberculosis

avian tuberculosis

bovine tuberculosis

cutaneous tuberculosis
infection with Mycobacterium tuberculosis uncommonly involves the skin; in dogs and cats it can occur as cutaneous ulcers, abscesses, plaques and nodules. More often, the term is used to describe infection with atypical mycobacteria.
fish tuberculosis
see fish tuberculosis.
Mycobacterium avium tuberculosis
causes a significant disease only in birds. In birds it is a chronic disease characterized by loss of body weight, poor egg production and eventual death. There are characteristic large gray, yellow or white tubercles in liver, spleen and intestinal wall. The disease is very persistent in a flock. In mammals it causes nonprogressive lesions, especially in lymph nodes, causing the animals to be positive to the tuberculin test.
Mycobacterium bovis tuberculosis
a chronic disease characterized by the development of tubercles or discrete nodular lesions in any organ. These may develop a necrotic center containing yellow-orange pus, often caseous. Diffuse involvement of lungs causing bronchopneumonia, and of uterus causing metritis, and of the udder also occur. The common clinical syndrome is wasting with localizing signs dependent on the organs involved. A common lesion in horses is osteomyelitis of a cervical vertebra.
Mycobacterium tuberculosis tuberculosis
infection with the human mycobacteria causes transient, usually lesionless infections in animals.
open tuberculosis
1. that in which there are lesions from which tubercle bacilli are being discharged out of the body.
2. tuberculosis of the lungs with cavitation.
skin tuberculosis
is characterized by chronic indurated lesions on the skin of the lower limbs of cattle. There are nodules on the path of corded lymphatics. Nonpathogenic acid-fast bacteria are present in the lesions and affected cattle are positive to the tuberculin test. Also occurs uncommonly in dogs and cats as single or multiple nodules, ulcers, abscesses or plaques in the skin. See also mycobacteriosis.
tuberculosis testing
tuberculin testing.
