Abstract： Objective To analyze the distribution of pathogenic bacteria and the drug resistance of main pathogen in pus and wound secretion specimens , and to provide the basis of reliable control infection for clinic .Meth-ods Specimens of 1 111 pus and 3 348 wound secretion were used for bacterial culture in Guangxi people′s hospital from January 2010 to December 2012 , and the isolated pathogen were used for identification and drug susceptibility a-nalysis.Results One thousand four hundred and forty-two pathogenic bacteria were isolated , the distribution of bac-teria was as follows: Gram positive cocci accounted for 33.9%( 489/1442 ) , Gram-negative bacteria accounted for 58.3%(840/1442), Fungi accounted for 6.2%(322/1442).The top of pathogenic bacteria checked out were as follows:Staphylococcus aureus accounted for 22.3%(322/1442), E.coli accounted for 18.0 %(259/1442), ver-digris accounted for 12.8%( 185/1442 ) , proteus accounted for 6.0%( 87/1442 ) , Acinetobacter accounted for 6.6%(95/1442), coagulase negative staphylococcus accounted for 4.9%(70/1442).Conclusion The wound pu-rulent infections of the patients in Guangxi people′s hospital are mainly caused by negative bacillus , but Staphylococ-cus aureus is the primary pathogen of infection , followed by E.coli bacteria , Pseudomonas aeruginosa .Rare bacteria as noka, aiken and actinobacillus are also isolated .Our results show that pathogenic bacteria of wound purulent infec-tion festering present diversification .Pathogens should be timely identified while treatment .And drug should be ra-tionally used according to the results of drug susceptibility .
