We have examined the expression of CDR1 ( Candida drug resistance gene) in different stress conditions. There was a significant but transient enhancement of CDR1 expression associated with elevated temperatures. Most noteworthy transcriptional activation was observed with miconazole and vinblastine. Interestingly, β‐estradiol and progesterone were also able to enhance CDR1 expression. Elevated levels of CDR1 and CDR2 (a homologue of CDR1 ) mRNA were found in some azole‐resistant clinical isolates of C. albicans . CaMDR1 (benomyl‐resistant) expression, however, did not differ among all the resistant isolates. Our results confirm the existence of multiple mechanisms of azole resistance in C. albicans .
