Abstract INTRODUCTION We describe the clinical and laboratorial features of oral candidiasis in 66 HIV-positive patients.

METHODS:

Polymerase chain reaction-based techniques were performed for differentiation of Candida spp. isolated from patients at a public teaching hospital in Midwest Brazil.

RESULTS:

Oral lesions, mainly pseudomembranous, were significantly related to higher levels of immunosuppression. Of 45 Candida isolates, 66.7% were C. albicans. Most of the isolates were susceptible to the antifungal drugs tested.

CONCLUSIONS:

Oral lesions were associated with higher immunosuppression levels. Lower susceptibility to antifungals by non-albicans isolates supports the importance of surveillance studies using susceptibility tests to aid in the treatment.
