This study revealed gram-positive bacteria in the three sub-tropical marine fish: Pseudocaranx Dentex (silver mackerel), Pagrus fish (perch) and Mugil Tsefal (sea mullet). He also highlighted the role of living fish part of fish body and the environment from the storage of gram-positive bacteria. A total of 266 strains of gram-positive bacteria were found conventional biochemical methods, VITEK, PCR with genus-and species specific primers and / or 16S rRNA gene sequence. Isolates were found to fall by 13 genera and 30 species. In fresh fish, epidermal staphylococci and Micrococcus Sheiz were the most frequent isolates. After storage in the surrounding, epidermal S., S. xylosus and Bacillus megaterium is not true, while S. warned, B. sphaericus, Brevibacillus borstelensis, Enterococcus faecium and Streptococcus uberis increased in frequency. Micrococcus Sheiz and S. warned were strattera 10mg the most common isolates of P. Dentex, and E. faecium and streptococci. uberis were the most frequent isolates P. fish and M. Tsefal. As for the different body parts of fish. E. faecium, streptococci. uberis and B. sphaericus were the most frequent isolates from the muscles, E. faecium, streptococci. uberis with gills and M. Sheiz from the intestine. This study found a variety of gram-positive bacteria in the subtropical marine fishes, but their abundance affected host fish, some fish body and the environment storage. .
