INTRODUCTION Fish mycobacteriosis is caused by the non-tuberculous mycobacteria. Infected fish are normally the primary source of infection, although non-tuberculous Mycobacteria can be found in the environment. The present study was designed to investigate the few recently found suspected cases of mycobacteriosis in Iranian ornamental fish tanks. MATERIALS AND METHODS Pathological specimens ...

Background: Epithelioid cell granulomas (ECG) are evident in the histology of various pulmonary diseases, including pulmonary tuberculosis (PTB); however, the diagnostic value of ECG in sputum cytology for patients with granulomatous lung diseases is unclear. Methods: To evaluate the value of identifying ECG in the sputum of patients with PTB and other respiratory diseases, we retrospectively r...

Mycobacterium ulcerans is an emerging environmental pathogen that causes debilitating, ulcerative disease in humans and other vertebrates. The majority of human cases occur in tropical and temperate regions of Africa and Australia, and outbreaks of piscine mycobacteriosis caused by M. ulcerans have been reported in disparate geographic locations spanning the globe. While exposure to a natural b...
