Distribution and drug resistance analysis of clinical isolated pathogenic bacteria in a hospital during 2013

Objective To understand the distribution and drug resistance of clinical isolated pathogenic bacteria in one hospital during 2013,so as to provide evidence for clinical rational use of drugs. Methods The clinical specimens were detected and analyzed by pathogenic detecting and drug sensitivity test in the hospital during 2013. Results A total of 3 324 strains were identified from clinical specimens during 2013 in this hospital. The constituent ratio of Gram positive strains was27. 8% and Gram negative strains was 72. 2%. Leading the first 3 places were Escherichia coli,Klebsiella pneumonia and Staphylococcus aureus. The detection rate of producing ESBLs stains in Escherichia coli and Klebsiella pneumonia were55. 8% and 25. 4% respectively. Acinetobacter baumanii and Pseudomonas aeruginosa had produced resistance to imipenem. There were no vancomycin- resistant staphylococci and enterococcus detected. Conclusion The infection of Gram-negative bacteria is prominent in clinical isolated pathogenic bacteria. The drug resistance situation of pathogenic bacteria is very serious. We should enhance resistance surveillance.
