A microdilution broth method was used to test 77 clinical isolates of Haemophilus influenzae and Haemophilus parainfluenzae, including beta-lactamase-positive and -negative strains, for susceptibility to ampicillin, chloramphenicol, and imipenem. Except for ampicillin against beta-lactamase-producing strains (MIC for 90% of strains [MIC90], greater than or equal to 128 micrograms/ml), all three antimicrobial agents had comparable in vitro activity (MIC90, less than or equal to 1 microgram/ml) against these bacterial strains.
采用微量稀释肉汤法检测了77株流感嗜血杆菌和副流感嗜血杆菌临床分离株,包括β-内酰胺酶阳性和阴性菌株,以测定它们对氨苄西林、氯霉素和亚胺培南的敏感性。除氨苄西林对产β-内酰胺酶菌株(90%菌株的最低抑菌浓度[MIC90],大于或等于128微克/毫升)外,这三种抗菌药物对这些细菌菌株具有相当的体外活性(MIC90,小于或等于1微克/毫升)。
