Respiratory and systemic mycoses are globally emerging as problems of increasing importance in infectious diseases. Among the various opportunistic infections, respiratory infections account for up to 70% of AIDS defining illnesses 65 (43.3%) samples were positive for fungal elements on culture. Of 65 isolates, 33 (50.7%) were yeasts and 32 (49.2%) were molds. Amongst the yeast isolates, 21 (63.6%) and 12 (36.3%) were collected from immunocompromised and immunocompetent patients respectively. 14 (42.4%) isolates were of C. albicans; 64.3% from the immunocompromised and 35.7% from the immunocompetent. The remaining 19 (57.5%) isolates of Candida were non albicans candida (NAC). Amongst the 32 (49.2%) mold isolates, 30 (93.7%) were found to be Aspergillus species. A. fumigatus was the most common (53.1%) followed by A. flavus (31.2%) and A. niger (9.3%). Candida isolated from the respiratory secretions does not always indicate invasive candidiasis nor does it indicate the need for antifungal therapy.
