Vulvovaginal candidiasis (VVC) is a common fungal infection among reproductive-age women and is increasingly challenged by the emergence of non-albicans Candida species and reduced azole susceptibility. This prospective cross-sectional study investigated 235 symptomatic reproductive-age women attending two healthcare facilities in Ho Chi Minh City, Vietnam, to determine VVC prevalence, Candida species distribution, pregnancy-associated patterns, antifungal susceptibility, and diagnostic performance. Vaginal swabs were cultured on Sabouraud Dextrose Agar and CHROMagar™ Candida, while species identification was confirmed by PCR-RFLP targeting the ITS region. Susceptibility to fluconazole and clotrimazole was assessed using the disk diffusion method. Candida spp. was detected in 55.7% of participants. C. albicans accounted for 50.3% of isolates, whereas non-albicans Candida species represented 49.7%, indicating a substantial species shift. VVC was more frequent among pregnant women, particularly in the third trimester. Most C. albicans, C. tropicalis, and C. parapsilosis isolates remained susceptible to azoles; however, C. glabrata showed markedly reduced susceptibility to fluconazole and clotrimazole. CHROMagar™ Candida reliably identified C. albicans but misclassified several non-albicans Candida isolates compared with PCR-RFLP. These findings highlight the need for routine species-level diagnosis, antifungal susceptibility testing, and strengthened VVC surveillance in reproductive and antenatal healthcare settings in Vietnam.
