Abstract：Objectives To analyze the distribution and drug resistance of pathogenic bacteria in neonatal department,and to provide criteria for rational clinical use of antibiotics. Methods Totally 15,796 specimens ob-tained from neonates were cultured according to the operation specification. The isolated pure strains were identified and their drug susceptibility was tested by VITEK-2 automated microorganism identification system. Results A to-tal of 1,125 strains of bacteria were isolated and the total detection rate was 7.1%. Of the total,742(66.0%)were gram-negative bacteria ,355(31.6%)gram-positive bacteria and 28(2.4%)fungi. K pneumonia was the most fre-quently isolated pathogen in gram-negative bacteria ,and staphylococcus the most frequently isolated pathogen in gram-positive bacteria. G-bacteria were highly resistant to ampicillin ,1st and 2nd generation cephalosporin. The re-sistant rates of K pneumonia,P aeruginosa and A baumannii to imipenem were>24.0%.Among the staphylococ-cus,35.7%were MRSA and 73.3%MRSCN. The antibiotic sensitivities of staphylococcusto vancomycin,Rina thia-zole alkanes and Tigecycline were 100.0%,but those to penicillin,cephalosporin and erythromycin low. Conclu-sion The dominant bacteria isolated from specimens obtained from neonates are gram-negativebacteria ,and they present extensive antibiotic resistance.
