Abstract

Forty-four yeasts belonging to the genera Pichia, Candida, Saccharomyces and Kluyveromyces were tested for their potential killer effect on 13 aerobic actinomycetes (6 Nocardia asteroides, 1 N. brasiliensis, 1 N. caviae and 5 Actinomadura madurae). Only a few yeast strains did not display any killer activity against the aerobic actinomycetes studied, thus confirming that the killer phenomenon is widespread among microorganisms. For epidemiological purposes, a killer system was developed. According to their susceptibility to the 9 killer yeasts chosen, it was possible to differentiate the Nocardia and Actinomadura isolates into biotypes. Fitting conditions of the killer system to potential sensitive microorganisms with different characteristics of growth are also discussed.
