ABSTRACT
Objective To understand the infectious pathogens distribution and drug resistance in the surgical departments of our hospital from 2007 to 2011 to provide the basis for the anti-infective therapy in the surgical patients.Methods TheVitek automatic microbial identification system was used to identify bacteria and fungi.The Kirby-bauer (KB)method was used to study the antibi-otic resistance in the pathogens isolated from the patients in the surgical departments.Results 1218 strains of pathogens were iso-lated,including 669 strains(55%)of Gram-negative bacteria,440 strains(36%)of Gram-positive bacteria and 109 strains (9%)of fungi.The top five of bacteria in turn were Escherichia coli in 182 strains(15%),Pseudomonas aeruginosa in 171 strains (14%), Staphylococcus aureus in 105 strains (9%),Klebsiella pneumoniae in 86 strains (7%)and Enterococcus faecalis in 61 strains(5%). Among 283 strains of Escherichia coli,Klebsiella pneumoniae and proteus mirabilis,the detection rate of ESBLs producing strains was 29.7%.Methicillin-resistant Staphylococcus aureus(MRSA)accounted for 63% of Staphylococcus aureus.The resistance rates of Staphylococcus and Enterococcus to multiple antibacterial drugs were above 50%.Enterobacteriaceae bacteria were more sensi-tive to carbapenems as well as compound antibacterial drugs containing enzyme inhibitor.The lowest resistance rate of Acinetobact-er to cefoperazone/sulbactam was 21.1%.Pseudomonas aeruginosa showed the most sensitive to compound antibacterial drugs con-taining enzyme inhibitor and its lowest resistance rate to cefoperazone/sulbactam was 17.4%.Conclusion The drug resistance phe-nomenon in the pathogens isolated from the surgical patients are relatively serious,this study provides some basis for the preventive antimicrobial drugs use in the perioperative period and the empirical medication in the infection therapy.
