[The incidence of nonfermentative gram-negative bacilli in the environment of the transplant unit, department of hemato-oncology, university hospital Olomouc].

: A study entitled "Surveillance of Infectious Complications in Hemato-oncological Patients" was conducted at the Department of Hemato-Oncology, University Hospital Olomouc from 1 July 2010 to 31 August 2011. During the study period, a total of 63 patients were hospitalized at that department and 33 stem cell transplants were performed, 21 autologous and 12 allogeneic. Microbial contamination was monitored in indoor air, on selected surfaces, and in health care providers (right hand smear, left and right nostril swabs and scalp hair smear). Gram-negative bacteria detected by culture were identified biochemically. Special attention was paid to nonfermentative Gram-negative bacilli which, based on the recent literature, should be considered as emerging causative agents of hospital infections.
