Objective To investigate the distribution and antibiotic resistance of bacteria isolated from clinical samples and to guide reasonable clinical treatment of antibiotics. Methods 3 598 strains of bacteria with their drug sensitivity test results during May 2010 to Apr. 2012 were reviewed retrospectively. Results In 3 598 strains of pathogenic bacte- ria, 2895 (80.5%) strains were gram-negative bacilli which containedd 784 ( 21.9% ) strains of Escherichia coli, 703 ( 19.6% ) strains of Pseudomonas aeruginosa, 462 ( 12.8% ) strains of Klebsiella pneumoniae, 399 ( 11. 1% ) strains of Acinetobacter baumannii. The positive rate of extended-spectrum [3-1actamases from Escherichia coli and KlebsieUa pneumoniae were 55.5% and 31.0%, respectively. Both of them were 100% sensitive to imipenem and meropenem, highly sensitive to cefoperazone/sulbactam and amikacin. The sensitivity of Escherichia coli were 99.23% and 91.96%, and the sensitivity of Klebsiella pneumoniae were 98.92% and 92.21%. The sensitivity ofpseudomonas aeruginosa to cefoperazone/sulbactam, amikacin and cefepime were 91.75%, 90. 18% and 89.47%, respectively. The sensitivity of Acinetobacter baumannii to cefoperazone/sulbactam, minocycline and ampicillin/snlbactam were 97.99%, 93.48% and 84.71%, respectively. There were 556 strains of gram-positive cocci( 15.5% ) which contained 139 strains of Staphylococcus aureus(3.9% ), 116 strains of coagulase-negative Staphylococci (3.2%), 141 strains of Enterococcusfaecalis (4.0%) and 101 strains of Enterococcus faecium (2.8%). The detection rate of MRSA andMRCNS were 21.6% and 56.0%, respectively. No strains of Staphylococcus and Enterococcus with resistance to van- comycin were detected. There were 147 (4.1% ) strains of fungi. Conclusion To understand the distribution of patho- gen bacteria and monitor its drug resistance dynamically can guide the reasonable use of antibiotics as well as control and delay the emergence of drug resistant strains.
