[Antagonistic action of Pseudomonas aeruginosa against Staphylococci, coliform bacilli and various types of Proteus].
Antagonistic activity of 2 fresh isolates and 3 collection strains of Pseudomonas aeruginosa against 177 microbial strains was determined with the method of late antagonism. Among the microbial strains there were 56 staphylococcal strains isolated from patents and carriers. 38 nontypable colon bacilli isolated from healthy persons, 59 enteropathogenic colon bacilli of various serogroups, 12 strains of Proteus and 12 colon bacilli, carriers of multiple drug resistance factors (R factors). All the cultures were sensitive to the antagonistic action of 5 or at least 3 strains of Pseudomonas used in the study. The most active antagonists were the fresh isolates of Pseudomonas as compared to the collection strains. Among the staphylococci S. aureus proved to be the most resistant to the antagonistic action of Pseudomonas as compared to S. epidermidis, the same as the strains isolated from carriers as compared to the strains isolated from patients. As for the enteric bacilli the most resistant were the strains of Proteus. Acquiring of transmissive R factors by the colon bacilli markedly increased their sensitivity to the antagonistic action of Pseudomonas.
