Abstract:
OBJECTIVE To analyze the pathogenic results and drug resistance of bacteria isolated from serous effusion specimens from Jan 2006 to Feb 2008 so as to provide evidence for clinical pathogenic analysis and selection of antibiotic. METHODS The bacteria identification and the antimicrobial susceptibility were assayed by routine methods. RESULTS The positive rate of pathogens was 6.80% from 721 serous effusion specimens.There were 49 strains of pathogens which included 15 of Gram-positive bacteria and 28 of Gram-negative bacteria and 6 fungi strains.The most frequently isolated pathogens were Enterobacteriaceae(32.65%) followed by Enterococcus(18.37%),and Pseudomonas aeruginosa(12.25%).The most active compounds against Enterococcus were vanconmycin and linezolid(100.00%),nitrofurantoin and tetracycline(66.67%);the most active compounds against Staphylococcus were vancomycin,linezolid and nitrofurantoin(100.00%),tetracycline and rifampin(75.00%);The most active compounds against Gram-negative bacilli were piperacillin/tazobactam(67.86%),imipenem(64.29%),tobramycin(60.71%),gentamicin(53.57%) and levofloxacin(46.43%). CONCLUSIONS The prevailing pathogens in serous effusion are Gram-negative bacilli,especially Enterobacteriaceae.Data collected in present study provide a valuable information for prophylactic and empirical antibiotic use for serous infection.
