[Serological studies of Pseudomonas aeruginosa bacteriophages]

Investigated were 11 phages isolated from lysogenic strains of Pseudomonas aeruginosa. Based on the results of the neutralization test the phages were divided into 3 clearly distinguished groups. The first group embraced phages P28 and C18, the second one--phages 5118, 05, 14, and 141, and the third one--phages 159 and 32. Bacteriophages 10, 12, and 149 produced slightly manifested (23 to 43 per cent) neutralization with P28 and 5118 sera. High-titer and specific antiphage sera were obtained.
