Abstract:
Objective To study the antimicrobial resistance changes of common pathogenic bacterial isolates in Guangzhou. Methods Disc diffusion test was used to measure the antibiotic susceptibility of 5063 strains collected from 13 hospitals in Guangzhou from 1998 to 2000 (Fastidious bacteria were detected by E test). Results From 1998 to 2000, the percentage of methicillin resistant Staphylococcus aureus was 45.3%,53.0%, and 50.8%, respectively, and that of methicillin resistant coagulase negative Staphylococcus was 64.1%, 86.0%, and 79.0% accordingly. There was no resistance to vancomycin in the strains of Staphyloccocas and there were 40.7%, 31.8% and 36.4% in E.coli and 43.1%, 42.7%, and 31.5% in Klebsiella found to be extended spectrum lactamases producing in the 3 years. Resistant rates of Enterobacter spp against the third generation cephalosporins increased. Resistant rates of P.aeruginosa against cefoperazone/sulbactam, ceftazidime,amikacin were changed unmarkedly in recent years. Conclusions The antimicrobial resistance of common pathogenic bacteria is serious in Guangzhou area. The surveillance of antimicrobial susceptibility is of great significance.
