title: [Bactericidal spectrum of pyocins on strains collected at Region IX and X hospitals in Chile].
abstract: The inhibitory effect of 5 pyocins produced by wildstrains of Ps aeruginosa was tested by qualitative and quantitative techniques. 313 strains of 4 species: E coli, P vulgaris, Ps aeruginosa and St aureus were assayed. It was shown that the most active pyocin was P37, which inhibited 276 out of 313 strains tested. About 80% of E coli and 90% of St aureus strains were inhibited by the pyocins under being tested. It was established that sensitivity to pyocin was not restricted to close-related species but extends to unrelated families also.
