[THE IDENTIFICATION AND DIFFERENTIATION OF BACTERIOPHAGES OF HUMAN PATHOGENIC VIBRIO].

The issue of identification and differentiation of large group of bacteriophages of human pathogenic vibrio is still unresolved. In research and practical applied purposes it is important to consider characteristics of bacteriophages for establishing similarity and differences between them. The actual study was carried out to analyze specimens of DNA-containing bacteriophages of pathogenic vibrio.

[O3:K6 serogroup vibrio parahaemolyticus - the causative agent of food toxic infection outbreaks in Primorsky region of Russian federation].

Aim: Comparative evaluation of biological properties of parahemolytic vibrios that had determined outbreaks and sporadic cases of food toxic infection in Primorsky Region in 2012 and previous years. Materials AND METHODS: 40 clinical strains of Vibrio parahaemolyticus isolated in 2012 were studied in comparison with 62 strains from this region that had been characterized by us previously. Virulence was evaluated by a complex method: hemolytic activitywas determined in Kanagawa test (KT), urease - in Kristensen medium.

[The bacteriophages Yersinia pseudotuberculosis: the detection in strains of different O-serovars and their identification].

The sample included five indicator pseudotuberculosis strains. The application of these strains permitted to isolate out of 161 strains of Y. pseudotuberculosis 9 bacteriophages identical by their morphologic and serologic characteristics but having individual particularities in their lytic activity.

[Identification of Vibrio mimicus bacteriophages].

Lysogeny was studied in Vibrio mimicus; the indicator V. cholerae El Tor strain was selected to identify phages. New V.
