To obtain information on the epidemiology of mycobacteriosis, water and air samples collected along the East Coast of the United States were examined for mycobacteria. Mycobacterium avium-intracellulare-scrofulaceum (MAIS) were isolated from 25% of the water, samples, mostly those from South Carolina, Georgia, and the Gulf states. Mycobacterium kansasii and Mycobacterium marinum were not found,...

Ichthyozoonotic Mycobacterium spp. poses health risks both to fish and humans. In this study, the presence of ichthyozoonotic Mycobacterium spp. was investigated in red mullet (Mullus barbatus barbatus) and surmullet (Mullus surmuletus), widely caught species in the Mediterranean and the Aegean Sea. A total of 208 fish samples, provided from fishermen of Mersin province (Turkey) were studied. U...

PE are peculiar exported mycobacterial proteins over-represented in pathogenic mycobacterial species. They are characterized by an N-terminal domain of about 110 amino acids (PE domain) which has been demonstrated to be responsible for their export and localization. In this paper, we characterize the PE domain of PE_PGRS33 (PE(Rv1818c)), one of the best characterized PE proteins. We constructed...

Mycobacteriosis, caused by numerous Mycobacterium spp., can be a devastating disease of both wild and cultured fishes. As no efficacious treatment exists, a vaccine against fish mycobacteriosis is essential for prevention and control of this disease. Thus, a DNA vaccine was constructed using the Mycobacterium marinum Ag85A gene that encodes one of the major secreted fibronectin-binding proteins...
