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. Quantitative differences in the response to the killer action of the mycelial and yeast forms in individual strains were also observed. To avoid retroconversion of the dimorphic forms, we used a modification of the conventional killer system.
比较评估了四种选定的酵母杀伤毒素对双态真菌申克孢子丝菌四个分离株的菌丝体和酵母形式的差异作用。结果证实,酵母杀伤现象存在于丝孢菌和酵母中,并且申克孢子丝菌的两种形态形式均对相同的酵母杀伤毒素敏感。还观察到个别菌株的菌丝体和酵母形式对杀伤作用的反应存在定量差异。为避免双态形式的逆向转化,我们对传统的杀伤系统进行了改良。
