An adult female eastern box turtle, Terrapene carolina carolina, presented with a proliferative soft tissue mass adjacent to the tail. Initial blood work revealed a moderate leukocytosis. Over the next five months, the lesion progressed despite treatment with a combination of surgical debridement and antibiotic therapy. Ultimately, Mycobacterium terrae was isolated from the locally extensive cu...

Mycobacterium triplex, a recently described slowly growing nontuberculous mycobacterium, was isolated from a Finnish patient with pulmonary mycobacteriosis. The disease was successfully treated with antimycobacterial drugs. The strain isolated, which was similar to the type strain but differed slightly from the species description, was regarded as a variant of M. triplex sensu stricto. Accordin...

The evolution between Mycobacterium tuberculosis infection and active tuberculosis is multifactorial and involves different biological scales. The synthesis of ESAT-6 or the induction of alveolar macrophage necrosis are key, but to understand it, it is necessary to consider the dynamics of endogenous and exogenous reinfection, drainage of lung parenchyma and respiratory mechanics, local fibrosi...

Although mycobacterial infections are more frequent in lung transplant recipients than in other solid organ recipients only occasional reports of infection from atypical Mycobacteria have been reported in patients receiving lung transplantation. We present a case of pleural and cutaneous infection due to Mycobacterium fortuitum in a double-lung transplant recipient. The infection was rapidly re...

Striped bass Morone saxatilis were infected intraperitoneally with approximately 10(5) Mycobacterium marinum, M. shottsii sp. nov., or M. gordonae. Infected fish were maintained in a flow-through freshwater system at 18 to 21 degrees C, and were examined histologically and bacteriologically at 2, 4, 6, 8, 17, 26, 36 and 45 wk post-infection (p.i.). M. marinum caused acute peritonitis, followed ...

The nontuberculous mycobacteria are typically environmental organisms residing in soil and water. These microorganisms can cause a wide range of clinical diseases; pulmonary disease is most frequent, followed by lymphadenitis in children, skin and soft tissue disease, and rare extra pulmonary or disseminated infections. Mycobacterium avium complex is the second most common cause of pulmonary my...
