Usual concentrations of antimycin A, rotenone and EDTA, individually or in combination, reduced aerobic growth rate and cell yield of Candida albicans to about half its normal level and to about the levels of previously-described acetate-negative, cytochrome-complete and aaa-deficient variants which

β¦ Synopsis
Candida albicans contains a cryptic cyanide a n d a n t i m y c i n A insensitive respiratory system. This alternate oxidase was f o u n d (i) at all growth rates from # = 0.05 to 0.26 in a chemostat culture and (ii) in both mycelial and yeast forms of the organism. Neither chloramphenicol nor cycloheximide prevented the expression of the alternate oxidase. Salicylh y d r o x a m i c acid was a potent inhibitor of the cyanide insensitive respiration. The respiration of m i t o c h o ndria grown in the presence of a n t i m y c i n A was n o t inhibited by cyanide or a n t i m y c i n A b u t was inhibited by salicylhydroxamic acid.

The initial clearance of Candida albicans in situ by hepatic tissue was investigated using the isolated perfused mouse liver model in combination with various monosaccharides. When 10(6) yeasts were infused into untreated ICR mouse livers, approximately 61 +/- 2% (mean + SEM) were recovered from the
We have developed a method for the isolation of a broad range of conditional lethal mutants of the pathogenic fungus Candida albicans. The method substantially alleviates the problems posed by the diploid nature, and the biased mutant spectrum, exhibited by most strains of this organism. We have use
