[Microbiological characterization of Listeria monocytogenes isolated from different sources in the Primorsky Territory].

The results of the bacteriological study of material, taken from humans, rodents, hydro-bios and environmental objects (including foodstuffs) in the Primorsky Territory, for the presence of L. monocytogenes bacteria are given. 83 bacterial strains of the genus Listeria were isolated. As revealed in this study, 25 of these strains belonged to L. monocytogenes (30.12%), 8 strains--to L. innocua (9.6%), 6 strains--to L. seeligeri (7.2%) and 2 strains--to L. ivanovii (2.4%). The greatest number of L. monocytogenes was isolated from foodstuffs and environmental objects. Some biological properties of L. monocytogenes were studied, the degree of their pathogenicity and sensitivity to antimicrobial preparations were determined.
