ABSTRACT
Objective To investigate the distribution and antimicrobial resistance of pathogens causing bacterial peritonitis,provide laboratorial guidance for rational use of antimicrobial agents.Methods Pathogenic strains iso-lated from peritoneal fluid specimen of patients with peritonitis in the Affiliated Hospital of Xuzhou Medical Univer-sity in 2011-2015 were collected,performed bacterial identification and antimicrobial susceptibility testing,distri-bution of pathogens and antimicrobial resistance were analyzed.Results A total of 491 strains were collected,in-cluding 291(59.26%)strains of gram-negative bacilli,196(39.92%)of gram-positive cocci,and 4 (0.82%)of fun-gi.The top 5 pathogens were Escherichia coli (30.14%),coagulase negative staphylococcus(12.22%),Staphylo-coccus aureus (10.39%),Klebsiella pneumoniae (8.55%),and Enterococcus faecium(6.52%).Antimicrobial re-sistance rates of Escherichia coli ,Klebsiella pneumoniae ,Acinetobacter baumannii ,and Pseudomonas aeruginosa to imipenem were 4.90%,31.04%,77.28% and 26.27% respectively.Methicillin-resistant Staphylococcus aureus (MRSA)and methicillin-resistant coagulase negative staphylococcus(MRNCS)accounted for 56.02% and 70.02%respectively.Conclusion The main pathogens causing bacterial peritonitis are gram-negative bacilli,Escherichia co-li ranks first;resistance of pathogens is serious,standard use of antimicrobial agents should be strengthened to re-duce the emergence of drug-resistant strains.
