ABSTRACT
This paper reports the results of environmental surveillance of yeasts in specific areas of two tertiary local hospitals. From March 2007 to February 2008, samples from the air of two public hospitals were collected on a monthly basis. The samples were collected through passive sedimentation method (day and night exposure) of Petri dishes. A total of 240 air samples from 10 hospital environments were analyzed. These environments presented similar contamination levels, from which 80 fungi isolates were isolated Candida parapsilosis (n = 34), Rhodotorula spp. (19), Trichosporon asahii (11), C. tropicalis (8), C. albicans (4), C. glabrata (1), C. guilliermondii (1), C. krusei (1) and Saccharomyces spp. (1). Regarding the presence of yeasts and climatic conditions, there were 40 strains (50 percent) in semi-critical areas (natural ventilation) and critical areas (air conditioned). Considering the presence of microorganisms with pathogenic potential, environmental monitoring is necessary to prevent possible hospital infections.
