Introduction: Patients treated at intensive care unitsare seriously exposed to fungal infections throug hair borne or haematogenic route because of their severe condition and/or invasive treatment.
Objective: The objective of the study was evaluation of fungal presence in the environment of an air conditioned intensive care unit at an infectious diseases
Material and methods: The fungi wereisolated, using a MAS-100 devicefrom the indoor air and using a Count-Tact imprint method from the walls, the floor and nurses' console in eleven rooms of the intensive care unit at the Gastroenterology, Hepatology and Infectious Diseases Clinic in the University Hospital CM UJ in Kraków.The
numbers of the fungi were measured twice daily, in the morning and in the evening in all of the rooms at ward under study. The fungal colonies cultured on the media
were counted and the fungi were identified according to accepted mycological procedures.
Results: A total of 120 air samples were collected, and fungal growth was observed in 114 of them.The mean numbers of fungi varied from 5 to 170 colony forming units
in one cubic metre (c.f.u./m3). Out of sixty imprints taken from the walls, the floor and nurses'console, fungal growth was observed in forty eight and the mean values varied from 0.04 to 3.45 colony forming units on one square centimetre (c.f.u./cm2). The mould genera Penicillium, Cladosporium and Aspergillus were present in all of the
rooms under study.
Conclusions: The numbers of fungal colonies in the indoor air did not exceed the class II of room cleanness according to Polish standards (the number of c.f.u./m3 <300).
