Analysis of Bacteria Culture of Clinical Specimens and Their Drug Sensitivity Test in 2003

Objective To investigate the species of bacteria which isolated from 1504 clinical specimens and their drug resistance, so as to guide the clinical usage of antibiotic. Methods The bacterial classification and drug sensitivity tests of 1504 strains of bacteria isolated from the in-patient cases from Jan to Dec in 2003 were analyzed retrospectively. Results Among those strains, 26.1% were Gram-positive bacteria, 49.7% were Gram-negative bacteria, and 24.2% were fungi. The main pathogens were Candida albicans, Escherichia coli, Staphylococcus aureus, Klebsiella Pneumoniae, and Pseudomonas aeruginosa. The infection appeared at respiratory tract, urinary tract and skin frequently. The drug resistance rate was increasing and some bacteria were multi drug resistance strains. Conclusions In order to reduce drug resistance strains, it is important that bacterial culture should be carry out actively and antibiotics must be based on the drug sensitivity test. of clinical significance to administer antibiotics based on drug sensitivity test.
