Regression lines were calculated for cephalothin, cephalexin, and cephaloridine by relating zone diameters of inhibition to minimal inhibitory concentrations (MIC) obtained in Mueller-Hinton agar and in Trypticase Soy Agar. A regression line was calculated for cephaloglycin by obtaining MIC values in Trypticase Soy Agar at pH 6.6. Regression lines calculated from MIC values in Mueller-Hinton agar were practically superimposable on those based on MIC values in Trypticase Soy Agar. Organisms susceptible by disc testing to cephalothin were usually susceptible to cephalexin and cephaloridine.
通过将在穆勒-欣顿琼脂和胰蛋白胨大豆琼脂中获得的抑菌圈直径与最低抑菌浓度(MIC)相关联,计算了头孢噻吩、头孢氨苄和头孢啶的回归线。通过在pH 6.6的胰蛋白胨大豆琼脂中获得MIC值,计算了头孢甘氨酸的回归线。从穆勒-欣顿琼脂中的MIC值计算出的回归线实际上与基于胰蛋白胨大豆琼脂中的MIC值的回归线重叠。通过纸片法检测对头孢噻吩敏感的菌株通常对头孢氨苄和头孢啶敏感。
