Abstract:
OBJECTIVE To understand epidemiologic situation of pathogens causing nosocomial infection,their resistance and changing pattern.METHODS A retrospective analysis was made upon the pathogens data from 2002 to 2006.The identification of bacteria was evaluated by VITEK32 and susceptibility test by K-B method.RESULTS The prevalence rate was 6.4%,and main infection sites were lower respiratory tract and urinary tract.Gram-negative bacteria(38.11%) stood first,followed by Gram-positive bacteria(25.25%) and fungi(22.54%).The mean resistance of Gram-negative bacteria was very high,from them Stenotrophomonas maltophilia(72.71%) and Chryseobacterium meningosepticum(68.13%) stood the highest.Besides Enterococcus faecalis,the mean resistance of Gram-positive bacteria exceeded 55.00%.Candida albicans stood first on the list of fungi.CONCLUSIONS The composition of pathogens is changing and showing serious resistances.It is important to strengthen nosocomial infection management and utilize drug rationally.
