Abstract

An ongoing survey of the susceptibility of the Bacteroides fragilis group of bacteria was continued at New England Medical Center in 1984 and 1985. A total of 1,229 strains were obtained from eight centers in the United States. These results were compared with those for 1,847 isolates tested in 1981 through 1983. The most active beta-lactam drugs were imipenem and ticarcillin-clavulanic acid (Timentin), which had a less than 1% resistance rate. No metronidazole- or chloramphenicol-resistant isolates were found during the 5 years of the study. Isolates obtained from blood, perinatal, and bone sites of infection were more resistant to a variety of antimicrobial agents. Susceptibility patterns of the members of the B. fragilis group varied at the eight hospitals and among species. These data indicate the need for determining the susceptibility patterns for the B. fragilis group of organisms at each hospital.

摘要

1984年和1985年,新英格兰医学中心继续对脆弱拟杆菌菌群的药敏情况进行一项持续调查。共从美国八个中心获取了1229株菌株。这些结果与1981年至1983年检测的1847株分离株的结果进行了比较。活性最强的β-内酰胺类药物是亚胺培南和替卡西林-克拉维酸(特美汀),耐药率低于1%。在该研究的5年期间未发现耐甲硝唑或耐氯霉素的分离株。从血液、围产期和骨感染部位获得的分离株对多种抗菌药物更具耐药性。脆弱拟杆菌菌群各成员的药敏模式在八家医院以及不同菌种之间存在差异。这些数据表明有必要在每家医院确定脆弱拟杆菌菌群生物体的药敏模式。
