Determining the frequency of Candida species in women with candidal vaginal infection frequency of Candida species in women with candida vaginal infection

Candidiasis vaginitis is an opportunistic and common mucosal infection. Although Candida albicans is the most common isolated species, other species of Candida such as Candida glabrata, Candida krusei, Candida parapsilosis, and Candida tropicalis have also increased significantly in recent years. The aim of this study was to identify Candida species in women with candidal vaginal infection in order to promote health in women.

This cross‑sectional descriptive study was performed on nonpregnant women of childbearing age who referred to health centers in Neyshabur in 2018. At the beginning of the study, 163 people entered the study and the culture results were positive in 68 of them. In vitro, culture was performed in subduxtrose agar medium containing chloramphenicol and gentamicin. Species identification was performed using Candida specific culture medium (Saburo dextrose agar and chloramphenicol). After culture, 15% of the residual wet slide with potash (KOH) was prepared and observed with a lens. Finally, the data were analyzed with SPSS software version 24.

The participants in the study were women with a mean age of 35.55 ± 5.47 and the average number of deliveries was 1.38 ± 1.15. In this study, the prevalence of C. albicans was 59.7%, C. tropicalis was 14.8%, C. krusei was 15%, and C. glabrata was 7.61% and also krusei and tropicalis were 3% simultaneously. Therefore, C. albicans was the most common species isolated from clinical specimens.

In this study, the most common species after albicans were C. tropicalis and cruciferous. Considering the role of C. glabrata in the development of resistance to antifungal drugs, the lower prevalence of this species in the present study can be associated with improved treatment outcomes in patients.
