The in vitro activity of minocycline against 1,028 bacterial strains was determined in parallel in Mueller Hinton Agar and Trypticase Soy Agar. The broad antibacterial effect of minocycline against gram-positive cocci and gram-negative bacilli is confirmed. Minimal inhibitory concentrations for gram-positive bacteria in Mueller Hinton Agar were at least twofold less than in Trypticase Soy Agar. Minimal inhibitory concentrations for gram-negative bacilli in Mueller Hinton Agar were usually fourfold less than in Trypticase Soy Agar.
在穆勒-欣顿琼脂和胰蛋白胨大豆琼脂中同时测定了米诺环素对1028株细菌的体外活性。证实了米诺环素对革兰氏阳性球菌和革兰氏阴性杆菌具有广泛的抗菌作用。在穆勒-欣顿琼脂中革兰氏阳性菌的最低抑菌浓度比在胰蛋白胨大豆琼脂中至少低两倍。在穆勒-欣顿琼脂中革兰氏阴性杆菌的最低抑菌浓度通常比在胰蛋白胨大豆琼脂中低四倍。
