The opportunistic fungal pathogen Candida glabrata
is the second most common isolate from bloodstream infections worldwide and is naturally less susceptible to the antifungal drug fluconazole than other Candida species.
is a haploid yeast that contains three mating-type like loci (MTL), although no sexual cycle has been described. Strains containing both types of mating information at the MTL1
locus are found in clinical isolates, but it is thought that strains containing type a information are more common. Here we investigated if a particular combination of mating type information at each MTL
locus is more prevalent in clinical isolates from hospitalized patients in Mexico and if there is a correlation between mating information and resistance to fluconazole and 5-fluorocytosine. We found that while both types of information at MTL1
are equally represented in a collection of 64 clinical isolates, the vast majority of isolates contain a-type information at MTL2
and α-type at MTL3
. We also found no correlation of the particular combination of mating type information at the three MTL loci and resistance to fluconazole.
