Oral candidosis and associated Candida species in HIV-infected Cambodians exposed to antimycotics.

Although human immundeficiency virus (HIV) infection is endemic in Southeast Asia, data on oral mycotic flora in this disease in Asians are sparse. The aim of this study was to determine the prevalence of Candida species in HIV-infected Cambodians with oral candidosis, unexposed (group 1) and exposed to antimycotics (group 2) and a healthy population (group 3). In 161 HIV patients with oral candidosis (group 1: 121 pts; group 2: 40 pts) and in 81 controls (group 3) swab samples of tongue and palate were obtained. Oral candidosis was detected in 100 and 70% of groups 1 and 2 respectively. Candida spp. were isolated from 91 and 100% of groups 1 and 2, respectively, and from 79% of controls. Candida albicans was the most common, with non-albicans species such as C. tropicalis and C. krusei being notable. Our data indicate that variants of oral candidal infections in HIV disease are similar to those seen in the pre-HAART era. The particularly high rate of C. krusei isolation in all groups is noteworthy.
