Pathogenic Bacteria of Abdominal Infection:A Clinical Analysis / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate pathogenic bacteria and prognosis of abdominal infection and take measures to prevent and control it.METHODS We analyzed the clinical material and prognosis of 31 patients with abdominal infection retrospectively according to the culture results of puncture and drain liquid from abdominal cavity from Nov 2007 to Nov 2008.RESULTS In 31 patients,5 were complicated with pulmonary infectionwhich the infection rate was 16.13%,and 7(22.58%) died.Totally 48 pathogenic strains were isolated from ascitic fluid culture,20 strains(41.67%) were Escherichia coli,11 strains(22.92%) were Enterococus.Some of coagulase-negative Staphylococcus,Streptococcus,Candida,Klebsiella pneumoniae,and Staphylococcus aureus were also isolated.The resistance rates of E.coli to cephalosporins were above 50.00%,to quinolones were above 65.00%.The susceptibility rates of E.coli to some ?-lactamases inhibitors and carbapenem were very high.The resistance rate of Enterococus to rifampicin was 63.64%,to piperacillin/tazobactam and piperacillin was 81.82%,to erythromycin was 100.00%.The susceptibility rates of Enterococus to teicoplanin,vancomycin,and linezolid were 100.00%.CONCLUSIONS The predominant pathogenic bacteria of abdominal infection are E.coli and Enterococcus.Abdominal infection tends to combine with pulmonary infection.The patients who got into multiple organ dysfunction syndrome have high mortality.
