Results of culture and detection of 360 bile samples and drug sensitivity test

To survey the main pathogenic bacteria and their resistance to antibiotics. Methods The 360 samples collected in the five years from patients with biliary tract infections were cultured and tested. Results Bacteria were cultured from 201 samples with a positive rate of 55.8%. Totally 220 strains were identified including 142 gram negative strains (64.5%) and 58 gram positive strains (26.4%), 20 fungal strains (9.1%). Resistance rates of E. coli and Kelbsiella to ampicillin, gentamycin, carbenicillin, and sulfanilamide were over 90%, while sensitive to other antibiotics. Multidrug resistance was observed in mucorracemosus, non-zymogen, enterococcus, staphylococcus etc. Fungus was still sensitive to antibiotics. Conclusion The main pathogens are E. coli, enterococcus, klebsiella, intestinal bacilli and other streptococcus that are resistant antibiotics with varied degrees. Thus monitoring work be strengthened and reasonable of drugs is indicated.
