A large diversity of Mycobacterium spp. has been isolated from striped bass Morone saxatilis in Chesapeake Bay, USA. The new species M. shottsii and M. pseudoshottsii are the dominant isolates, while the classical fish pathogen M. marinum is found much less frequently. M. fortuitum and M. chelonae, other Mycobacterium spp. known to commonly infect fishes, have not yet been aseptically isolated from striped bass within Chesapeake Bay. While M. pseudoshottsii and M. shottsii have been phenotypically and genotypically characterized, other less common mycobacterial isolates have not. In the present study, we describe 17 photochromogenic isolates from Chesapeake Bay striped bass using phenotypic characterization and multilocus sequencing of 16S rRNA, hsp65 and rpoB genes. Genetic characterization reveals that these isolates are related to widely divergent portions of the mycobacterial phylogeny; however, some interesting trends are observed, such as a majority of isolates (10/17) belonging to the M. simiae-related grouping. Five additional isolates were assigned to the slow-growing mycobacteria (including 2 identified as M. marinum), while 2 are clearly shown to belong genetically to the fast-growing mycobacteria.

“…At the present, Mycobacterium marinum, M. fortuitum and M. chelonae (Sneath et al, 1986;Frerichs, 1993) in the genus Mycobacterium are known as fish pathogens (Chen et al, 1997;Heckert et al, 2001) and M. marinum sometimes causes skin disease in human (Lim et al, 2000). In addition, Heckert et al (2001), Rhodes et al (2003) and Rhodes et al (2005) reported new species, M. chesapeaki, M. shottii, and M. pseudoshottii, respectively, from striped bass Morone saxatilis in Chesapeake Bay. Levi et al (2003) also reported a new species, M. montefiorense from captive moray eels Gymnothorax funebris and G. moringa.…”

Mycobacterium marinum Infection in Cultured Yellowtail Seriola quinqueradiata in Japan

et al. 2007

ABSTRACT-Recently, Mycobacterium infection has been observed in cultured yellowtail Seriola quinqueradiata in Japan but not studied in detail. Diseased fish were lethargic, anorexic and emaciated, and showed hemorrhagic cutaneous ulceration and ascites. The necropsy and histopathological features showed that disseminated necrosis and numerous white nodules were found in the kidney, spleen, liver and heart. Numerous acid-fast bacteria were detected in the above tissues and granulomas. Myositis, hepatitis, splenitis and nephritis due to granulomas and gill inflammation were histologically observed. Almost all granulomas were classified into soft tubercletype. All bacteria isolated from the diseased fish were Gram-positive, acid-fast, rod and non-motile. As a result, they were classified into the genus Mycobacterium. The isolates were identified as Mycobacterium marinum on the basis of biological and biochemical characteristics and the analysis of a partial 16S rRNA gene sequence. An experimental infection test showed that a representative isolate had pathogenicity to yellowtail with disease signs similar to those of naturally affected fish. This is the first report on M. marinum infection in cultured yellowtail.

“…Ucko et al (16) used sequences of almost the entire 16S rRNA gene to characterize and seek heterogeneity of M. marinum strains isolated in Israel and other geographical regions. Furthermore, sequence analysis of this gene has been used to analyse several novel aquatic mycobacteria species (21)(22)(23). However, in these studies only a few species were included.…”
