Six of 36 strains of Streptococcus pneumoniae isolated in our laboratory during 1977 showed relative resistance to penicillin G. This level of resistance was detectable only by the broth dilution method. Using the disk diffusion method, all six strains appeared susceptible (zone size > 29 mm).
1977年在我们实验室分离出的36株肺炎链球菌中,有6株对青霉素G表现出相对耐药性。这种耐药水平只能通过肉汤稀释法检测到。使用纸片扩散法时,所有6株菌看起来都是敏感的(抑菌圈直径>29毫米)。
