Incidence of Candida species isolated from human skin and nails: a survey.

Distribution of Candida species was investigated by examining 245 samples from skin lesions and nails. The isolates were identified using standard laboratory methods including germ tube test, micromorphology of colonies on rice agar, the commercial kit, saccharide assimilation and fermentation tests. Eight species of Candida were identified: C. albicans accounted for 56.4% of the isolates, C. parapsilosis 29.1, C. tropicalis 7.8, C. pulcherrima 2.9, C. guilliermondii 1.5, C. krusei and C. zeylanoides for 0.9% each, and C. robusta for 0.5%. The factors significantly associated with colonization were prolonged antibiotic therapy, parenteral nutrition, low birth body mass of infants, intubation, duration of stay in hospital, indwelling intravenous catheter, malignancies, diabetes, surgery, and obesity.
