Abstract:
Objective To understand the main pathogenic bacteria distribution and drug susceptibility in the common bile duct calculi with infection ,so as to provide the basis for rational use of antimicrobial agents .Methods Data′s of 296 cases of bile specimens treated from January 2011 to December 2013 were retrospectively surveyed and drug resistance of bacteria culture results were analyzed .Results Among all the 296 cases ,there were 199 cases of pathogenic bacteria in bile specimens ,the positive rate was 67 .23% ;among them ,there were 21 cases of two kinds of bacteria ,a total of 220 strains of pathogenic bacteria were detected ,and among them there were 158 strains of gram negative bacteria ,accounting for 71 .82% ;there were 46 strains of gram positive bacte‐ria ,accounting for 20 .91% ;there were 16 strains of fungi ,accounting for 7 .27% ;the lowest resistance of gram negative bacilli lies in amikacin ,followed by tazobactam ,aztreonam ,three to four generations of cephalosporins and quinolone .Gram negative bacilli has the highest drug resistance to pseudomonas aeruginosa and e .coli ,and it has a drug resistant rate higher than 50 .00% to most anti‐microbial drugs .Gram positive cocci has 0 drug resistance rate to add ring element ,has a drug resistance rate lower than 30 .00% to vancomycin and rina thiazole amine ,and has highest drug resistance rate (70 .00% -100 .00% ) to erythromycin ,clindamycin and chlorine lincomycin .Conclusion Among all the 296 cases of common bile duct calculi bile with biliary tract infection ,the main path‐ogenic bacteria were e .coli ,klebsiella pneumoniae ,eosinophilic malt narrow and excrement enterococcus bacterium ;and the drug re‐sistance to penicillin is highest .
