Objective. - Determine the place of vulvo-vaginal candidiasis (WC) in the lower genital infections and seek risk factors among women in Benin. Patients and methods. - The study was conducted in the laboratory of mycology of Hopital de la Mere et de I'Enfant Lagune (Homel) from 1st March to 31st July, 2013. It involved all the women who were asked a vaginal swab and gave their consent in written form.

Results. - One hundred and thirty-one women were included in the study period. Clinical signs were dominated by vaginal discharge (74.8 %), followed by vulvar pruritus (51.9 %) and dyspareunia (36.6 %). Culture on Sabouraud was positive in 51 cases or 38.9 %. Candida albicans was isolated in 96.1 % of cases, against 3.9 % of Candida glabrata. The risk factors involved were: pregnancy, antibiotics, synthetic underclothing and frequent wearing tight pants. In addition of Candida, Gardnerella vaginalis was found in 36.6 % of samples with an association with C. albicans in 28.2 % of cases. Conclusion. - This study showed that vulvovaginal candidiasis is the leading cause of lower genital tract infections in women in Benin with involvement of several risk factors which research is needed to develop appropriate preventive measures.
