Abstract:
OBJECTIVE To estimate the distribution of pathogens of nosocomial infection in intensive care units,the sites where infections often taken place and the related antibiotic-resistance of bacteria.METHODS Various samples of bacteria from intensive care units have been examined by applying half-automatic analyzer ATB Expression,with bacteria inspecting cards and drug-sensitivity cards,all from Bio-Merieux,France.RESULTS Totally 153 strains of nosocomial pathogens have been found,where Acinebacter baumannii,fungi and Pseudomonas aeruginosa ranked top three,with rates of 32.0%,16.3%,and 15.0%,respectively.About 45.8% of pathogens were found in samples from the lower respiratory tract.Approximately 4.3% of A.baumannii showed drug-resistance to imipenem.However,more than 50.0% of A.baumannii presented its strong drug-resistance to rest of eight regular antibiotics.CONCLUSIONS A.baumannii is a dominating pathogen to cause nosocomial infection in intensive care units,and has shown strong multi-drug-resistance,which should incur high clinical attention.It comes to be crucial to highlight sanitization and sterilization operation,applying proper antibiotics in order to reduce appearance of bacteria with drug-resistance.
