High diversity of Candida glabrata in a tertiary hospital-Mwanza, Tanzania.

Candida glabrata is a genetically diverse human pathogenic yeast, whose subpopulations have been documented to vary geographically. Here, we report MLST genotypes and antifungal drug susceptibility of C. glabrata isolates from Africa. Among 47 mostly urogenital isolates, we found 13 sequence types, amounting to a 27% genetic population difference. More than half of the isolates were of novel sequence types. ST18 was most predominant and had reduced susceptibility to fluconazole. There was clear segregation of STs between urine and vaginal specimen. In Tanzania, the C. glabrata population is genetically diverse, and divergent from those seen in other countries.
