the history, clinical signs and post mortem lesions are suggestive of the diagnosis. Confirmation of the species of acid fast bacteria should be undertaken by culture or genetic identification. The tuberculin test is available for poultry with avian tuberculin (0.05 - 0.1ml) being injected into one wattle (use a 1cm, 25g needle) and 48 hours later the prescence of swelling and heat being compared with the uninocculated wattle. This test will detect about 80% of positive birds and can miss birds with severe lesions. A stained antigen, whole blood agglutination test and an ELISA test are also available. As none of these tests will detect 100% of infected birds they will need to be used in planned monitoring programme. ...

Bacteria of the Mycobacterium avium-intracellulare complex causing Avian Tuberculosis in birds are organisms of the air-freshwater interface, and are found most commonly in temperate regions, surviving best out of sunlight. Shady conditions and completely enclosed houses, by protecting the bacteria from sunlight, may enhance survival and thereby increase contamination (J7.32.w1, J44.72.w1, P3.1990-1991.w1).. Bacteria of the Mycobacterium avium-intracellulare complex causing Avian Tuberculosis in birds can usually survive for at least four years and possibly up to seven years in the environment. Sites on which waterfowl have been maintained for many years may have high levels of contamination, due to excretion of bacilli by infected birds over time (B32.7.w43, B14, P3.1990-1991.w1, P11.1993.w1).. The types commonly recognized as Mycobacterium avium (serotypes 1, 2 and 3) are the major causes of disease in birds (B15 ...

In veterinary dermatology, domestic carnivores sporadically are found with ulcerated lesions characterized by a prolonged course of evolution and by relative unresponsiveness to the usual drug therapy; this condition can be due to infections caused by microorganisms of the Genus Mycobacterium. Due to the scarcity of its description in Brazilian literature, and due to the inusitate lesions and response to preconized therapy, two cases of canine mycobacteriosis attended at the University Veterinary Teaching Hospital of the FMVZ/USP are then described. The adult bitches (German Shepherd and Doberman Pinscher) were found with ulcerated lesions at the posterior side of the pinna w ith granulomatous aspect and with exudation and covered by hemorrhagic crusts without showing any detectable satellite lymphadenomegalia or any symptoms in other systemic organs. Physical, hematologic and radiographic examinations were performed and lesions have been curetted and biopsied through punching technique, and ...

TY - JOUR. T1 - Mycobacteriosis in cultured striped bass from California.. AU - Hedrick, Ronald. AU - McDowell, T.. AU - Groff, J.. PY - 1987/1/1. Y1 - 1987/1/1. N2 - Striped bass (Morone saxatilis) juveniles raised in an intensive culture system had chronic mortality resulting from infections with Mycobacterium marinum. Approximately one-half of a population of 900 yearlings succumbed to the disease and 80% of those remaining were infected. The bacteria were isolated on Petrignanis medium after 7 days at 25 C and subcultures grew at temperatures from 20 to 37 C. The disease was characterized by systemic nodular lesions in all major organs. Older tubercles contained numerous acid-fast bacilli. Chemotherapy by feeding rifampin (6 mg/100 g of food for 60 days) was not an effective treatment. Subclinical mycobacteriosis in adult striped bass may be the source for vertical transmission to their progeny.. AB - Striped bass (Morone saxatilis) juveniles raised in an intensive culture system had ...

Annual striped bass tag-recapture studies in Maryland and Virginia waters indicate that since the late 1990s and concurrent with the first reports of this disease, natural mortality (e.g. mortality other than that attributable to fishing) has gone up significantly in the Bay. This has generated concern among scientists, fishermen, and resource managers that the disease is having significant adverse impacts on the stock.. One of our recent studies provides first evidence that disease-associated mortality is occurring in Bay striped bass. However, we do not yet know the extent of this mortality, nor do we understand the ecology of the mycobacteria (e.g. where in the environment they are found), the routes of transmission for the infection or the environmental stress (e.g. temperature, hypoxia etc.) that modulates disease expression. We believe this infectious disease is a grave concern and that additional research is desperately needed to find answers to the many remaining scientific ...

We wish to point out that in this case, no actual tuberculosis was present; rather, the patient had non-tuberculous mycobacteriosis (NTM), caused by Mycobacterium avium intracellulare. The infection was finally successfully treated over a period of 2...
