ABSTRACT
Objective To statistically analyze the bacterial flora change and drug resistance situation in the patients with bacteri‐al infection to provide reference for clinical rational drug use and the management of nosocomial infection .Methods The clinical samples were conventionally isolated and cultured .The bacteria identification and drug sensitivity test were performed by using the bioMerieux company VITEK2 automatic microorganism analyzer .The confirmation test of drug susceptibility adopted the disk dif‐fusion method recommended by the American Clinical and Laboratory Standardization Committee (CLSI) .Results The sample sources in the hospital infection during 2011-2013 were main sputum ,secretions and midstream urine ;the main infectious bacteria showed the increasing trend ,the top 5 of bacteria wereEscherichia coli (ECO) ,Klebsiella pneumoniae (KPN) ,Acinetobacter bau‐manii (ABA) ,Pseudomonas aeruginosa (PAE) ,Staphylococcus aureus (SAU);the top three of common multi‐drug resistant bacte‐ria were ABA ,PAE and ECO ,their constituent ratio during these three years had a small amplitude increase ;the antibiotics for Gram negative bacilli (G -) resistance rate of more than 70% during these 3 years wereampicillin ,cefuroxime sodium and cefu‐roxime axetil;the antibiotics for Gram positive cocci (G+ ) resistance rate of more than 70% during these 3 years were penicillin and erythromycin ..Except for 4 cases of Enterococcus faecalis ,no other vancomycin‐resistant strains were found .Conclusion The sam‐ple source of bacterial infection is dominated by sputum ,the gram negative bacteria are the main force of hospital infection ,showing a increasing trend every year ,multi- drug resistant strains are also continuously rising ,penicillin is unsuitable to the clinical treat‐ment of bacterial infection ;imipenem has very high sensitivity to ECO and KPN .The hospital should attach great importance to the infection management ,strengthen the application and management of antibiotics ,decrease the outbreak and prevalence of bacterial infection and reduce the increase of drug resistant strains .
