In vitro susceptibility tests were performed on 84 strains of Clostridium difficile to 11 antimicrobial agents. All isolates were from the stools of patients with antibiotic-associated diarrhea or colitis in which there was a cytopathic toxin that was neutralized by Clostridium sordellii antitoxin. Over 95% of the strains were susceptible to vancomycin, penicillin G, ampicillin, and metronidazole at concentrations of 4 microgram/ml. Susceptibility to clindamycin was variable; 60% of the strains were susceptible at 1 microgram/ml, and 9% were resistant at 128 microgram/ml. Studies of individual isolates showed that a major portion of the strains were relatively susceptible to the antimicrobial agent implicated in causing the disease.
对84株艰难梭菌进行了11种抗菌药物的体外药敏试验。所有分离株均来自抗生素相关性腹泻或结肠炎患者的粪便,这些患者的粪便中存在一种被索氏梭菌抗毒素中和的细胞病变毒素。超过95%的菌株对浓度为4微克/毫升的万古霉素、青霉素G、氨苄西林和甲硝唑敏感。对克林霉素的敏感性存在差异;60%的菌株在1微克/毫升时敏感,9%的菌株在128微克/毫升时耐药。对单个分离株的研究表明,大部分菌株对与疾病发生有关的抗菌药物相对敏感。
