Broth dilution MICs of metronidazole against 38 strains of Clostridium difficile (0.13 microgram/ml) and 11 strains of Peptostreptococcus anaerobius (0.11 microgram/ml) were lower than those of tinidazole (0.16 and 0.17 microgram/ml, respectively). As molar concentrations the nitroimidazoles were equally active. The MICs of the two drugs correlated positively, and the relative activity of tinidazole increased with decreasing susceptibility of both species.
甲硝唑对38株艰难梭菌的肉汤稀释最低抑菌浓度(0.13微克/毫升)和对11株厌氧消化链球菌的肉汤稀释最低抑菌浓度(0.11微克/毫升)低于替硝唑(分别为0.16和0.17微克/毫升)。以摩尔浓度计,硝基咪唑类药物具有同等活性。两种药物的最低抑菌浓度呈正相关,且替硝唑的相对活性随两种菌敏感性降低而增加。
