For one year (August 2010 to July 2011), microbial contamination of the indoor air in the Transplant Unit of the Haemato-Oncology Clinic, Olomouc University Hospital was monitored monthly. Twenty sampling sites were singled out and a total of 240 indoor air samples were collected. An MAS-100 air sampler (Merck, GER) was used, air flow rate of 100 liters per minute, 1 minute. The measured values of indoor air temperature were stable. The relative air humidity ranged from 17% to 68%. The highest average value of microbial air contamination was found in the "staff entry room" (1170 CFU/m3). The lowest microbial air contamination (150-250 CFU/m3) was measured in the patient isolation units. The most frequently isolated bacterial strains were coagulase-negative staphylococci (94.3%), followed by Micrococcus spp. (67%) and Bacillus subtilis (11%). It can be assumed that the -source of these airborne bacterial strains are both patients and medical staff. They are classified as -opportunistic pathogens and as such can cause hospital infections among haemato-oncology patients.
