Surveillance of nosocomial fungal infections in a burn care unit

Abstract

A survey was conducted to trace the source of nosocomial fungal infections in the burn care unit of Nehru Hospital, Chandigarh, India, by collection of samples from wounds of 25 severely burnt patients and their surroundings. The environmental sampling revealed predominant fungal contamination by dematiceous hyphomycetes, aspergilli, Penicillium, Fusarium and yeasts (Candida albicans, Candida tropicalis, Candida krusei, Candida parapsilosis), whereas the colonising or invading fungi from the patients were Aspergillus flavus and yeasts of the genus Candida (C. albicans, C. tropicalis, C. krusei, C. parapsilosis, Torulopsis glabrata). This study thus corroborates the more pathogenic potential of some of the environmental fungal isolates located in the vicinity of the immunocompromised patients and stresses the need for decontamination of the environment of the burn care unit.
