Taxonomic structure of bacterial community for mussel Crenomytilus grayanus digestive system from coastal waters of Vladivostok city, which is characterized by considerable anthropogenic impact was studied. Specimens of Micrococcaceae family predominated in the mollusc microscopic flora by the quantity of selected strains (62%). The order of Actinomycetales (namely genera of Actinomyces and Pimelobacter) were large (11%). In addition, there were numerous representatives of Enterobacteriaceae family (9%), Vibrio genus (9%), and Paracoccus genus (9%) selected. There were found such pathogenic and opportunistic microorganisms, as Escherichia coli, Listeria monocytogenes, and Klebsiella spp in microbial communities of mussels. Even though pathogenic microflora does not predominate in the biotic community, it nevertheless shifts the balance to increase extrinsic microflora within the hydrobiont. Detection of such potentially harmful bacteria indicates the insufficient sanitary and epidemiological state of the water area researched, the bay persistently polluted with municipal domestic drain waters.
