Killer phenomenon in pathogenic yeast.
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...
متن کاملReevaluation of the yeast killer phenomenon.
The killer effect of 36 Hansenula, Pichia, Saccharomyces, and Candida species on 26 hyphomycetes isolates, 1 isolate of the achlorophyllous microorganism Prototheca, 4 isolates of the lipophilic yeast Malassezia, 1 isolate of the aerobic actinomycete Nocardia, and 19 isolates of bacteria was studied. The killer phenomenon, which was previously considered to be restricted to yeasts, was found to...
متن کاملYeast killer systems.
The killer phenomenon in yeasts has been revealed to be a multicentric model for molecular biologists, virologists, phytopathologists, epidemiologists, industrial and medical microbiologists, mycologists, and pharmacologists. The surprisingly widespread occurrence of the killer phenomenon among taxonomically unrelated microorganisms, including prokaryotic and eukaryotic pathogens, has engendere...
متن کاملYeast killer toxins and dimorphism.
The differential action of four selected yeast killer toxins on the mycelial and yeast forms of four isolates of the dimorphic fungus Sporothrix schenckii was comparatively evaluated. The results confirmed that the yeast killer phenomenon is present among hyphomycetes and yeasts and that both morphological forms of S. schenckii are susceptible to the action of the same yeast killer toxin. Quant...
متن کاملInduction of yeast killer factor mutations.
Two related killer strains of Saccharomyces cerevisiae were mutagenized and screened for nonkiller variants. About 20% of the mutants derived from one strain lacked all detectable double-straned ribonucleic acid (dsRNA). About 70% of the mutants from the other strain lacked one of the dsRNA species normally associated with the killer factor and had in its place another species of dsRNA with a l...
