Abstract
Potentially pathogenic yeast strains from four genera,
Candida, Cryptococcus, Torulopsis
, and
Trichosporon
, were examined for killer activity and sensitivity using
Saccharomyces
and
Torulopsis
strains of known killer status. Tests were performed by using a streak method and by concentration of culture fluid by lyophilization. Of 236 strains examined, killers were found with low prevalence among
Torulopsis
and
Cryptococcus
strains;
Candida
and
Trichosporon
isolates showed no killing activity. Different specificities of killing activity were observed among strains of a single species. Sensitive strains were found with varying frequencies in all genera but
Trichosporon
.
