Bacterial suscep-tibility testing was carried out using Kirby-Bauer method. Fourteen different antibiotic discs and a cefinase disc(BBL Sensi disc)were used. Among 2050 isolates 540(26.3%)were Gram(+) cocci,77(3.8%)Gram(-)cocci,1433 Gram(-)bacilli.

• 为了解医院细菌耐药性，采用16种抗菌药纸片、Kirby－Bauer琼脂扩散法监测了上海6家医院临床分离细菌的耐药性，结果共2050株细菌中540株（26.；3%25）革兰阳性球菌，77株（3
