Abstract The study of the nosocomial infections of fungic origin has attained importance in the last years, due to the rise in the number of patients that are inmunocompromised and susceptible to suffer this kind of infection. The objective of the present study was to evaluate the frequency of filamentous fungi and yeast, present in the environment of the Intensive Care Unit, operating and newborn children rooms of the Hospital Universitario "Antonio Patricio de Alcalá" (HUAPA) from the city of Cumaná, Sucre State, Venezuela. The recount of colony forming units/plate (UCF/plate) of the filamentous fungi and yeast was done in Petri plates with Sabouraud dextrose agar, which were exposed in the different studied areas. Eventually, the fungus colonies found were isolated and identified. The area that presented the highest average of UCF/plate was the Intensive Care Unit (9 UCF/plate). The isolated genus of filamentous fungus in higher proportion were Aspergillus (46,80%), Penicillium (19,19%) and Fusarium (11,06%). The isolated species with more frequency were Aspergillus niger (24,80%), Aspergillus flavus (10,54%) and Fusarium solani (9,52%). Rhodotorula glutinis was the isolated yeast with most frequency and different species of the genus Candida and the genus Criptococcus were isolated as well.
