Objective:Candida is the most common cause of fungal infections. The aim of this study was to fill the gaps in the current knowledge on the frequencies of micronuclei and nuclear anomalies, and the nucleus/cytoplasmic ratio in genital candidiasis. Study Design: A total of 88 Papanicolaou- stained cervical smears, which comprised Candida spp. (n = 44) and control cases with no infectious agent (n = 44), were studied. In each smear, cells with micronuclei and nuclear anomalies were counted in 1,000 epithelial cells and also nuclear and cellular areas were evaluated using image analysis software at a magnification of ×400. Results: The frequencies of micronucleated and binucleated cells and cells with perinuclear halos, and the nucleus/cytoplasmic ratio of epithelial cells were higher in the Candida-infected group compared with the control group (p < 0.05). Conclusions: Genital candidiasis is able to induce changes in the size and shape of epithelial cells. The nuclear/cytoplasmic ratio and the frequency of micronuclei may reflect the DNA damage in the cervical epithelium. Micronucleus scoring could be used to screen the genomic damage profile of epithelial cells in candidiasis.
