Introduction: The vaginal flora is a dynamic ecosystem that can be easily altered. Although, there are four causes of vaginal discharges which cover almost 95% of vaginaitis. Candidal Vaginaitis is an infection of the vagina’s mucous membranes by Candida albicans (CA). Present study attempted to Candidal Vaginitis in women referred to health centers in Yazd and the role of innate & cell-mediated immunity against Candidal Vaginitis.
 Materials and Methods: A cross-sectional study conducted from September 2011 to September 2012 in Yazd city. A total of 360 women were recruited. The collection of material for diagnosis is ideally performed during a comprehensive pelvic examination using a speculum for diagnosis of CA with identify vaginal pH smear preparing and staining and culturing.
 Results: Finally all of 360 women that observed and tested, 120 (33.33%) of them have involved and 240 (66.67%) have not involved. from 120 infected women, 55paitents had Bacterial vaginosis (15.6%) 40 patients had Ca (10.8%) and 25 patients had Trichomonas vaginalis (5.9%). Despite the role for cell-mediated immunity in host protection against the majority of mucosal CA infections, studied has been in women with recurrent vaginitis, in HIV-infected women. Thus, current investigations have been focused specifically on innate and acquired immune responses against CA at the vaginal mucosa instead of Vulvovaginal Candidiasis being caused by defective or dysfunctional CD4+ T helper 1-type cell-mediated immune reactivity.
Conclusion: Strongly suggest that distinct vaginal lymphocyte subsets participate in the adaptive anti-Candida immunity at the vaginal level, with the vaginal CD4_ T cells probably playing a major role.
