[Phagovars of halophilic vibrios]

The results of the phage typing of 164 halophilic vibrios revealed the most frequent combinations of lysing monophages, denoted by numbers: 1 (A, B, C, D), 2 (B, C, D), 3 (B, C) and 4 (C). In accordance with the proposed scheme, the phage typing of 398 cultures from different ecosystems was carried out. Phagovar was determined in 77.1% of the cultures. Most frequently occurred phagovars 1 (31.9%), 4 (15.8%), 3 (6%), and 2 (3.7%). Their proportion was 61%. 11 other phage combination causing the lysis of the cultures constituted 16.1%; 22.9% of the cultures could not be types. The use of the proposed scheme of phage typing permitted the determination of the temporal, regional, ecosystemic features of the circulation of halophilic vibrios in different ecosystems and regions, which was important for epidemiological analysis.
