[The isolation and characteristics of cloned strains of Pseudomonas pseudomallei phages].

On the basis of museum strains of the melioidosis agent Pseudomonas pseudomallei, 14 pure lines of bacteriophages were isolated belonging to morphological groups IV and V according to the classification by A. S. Tikhonenko. These phages show a broad bacteriolytic range as far as museum P. pseudomallei cultures are concerned. It was determined that some phages isolated from the same melioidosis culture and belonging to the same morphological type display different bacteriolytic activity. It is demonstrated that some strains of melioidosis agent are characterized by polylysogeny.
