A total of 986 isolates of Haemophilus influenzae from patients with respiratory tract infections in 45 United States medical centers were characterized during the winter of 2002-2003. beta-Lactamase production was noted with 26.2% of isolates; 14.6% were resistant to trimethoprim-sulfamethoxazole. Resistance to other relevant antimicrobial agents was extremely uncommon. In comparison to the results of four previous national surveys conducted since 1994, the prevalence of beta-lactamase production with this pathogen appears to be decreasing.
2002年至2003年冬季,对美国45个医疗中心呼吸道感染患者的986株流感嗜血杆菌进行了特征分析。26.2%的分离株产生β-内酰胺酶;14.6%对甲氧苄啶-磺胺甲恶唑耐药。对其他相关抗菌药物的耐药情况极为罕见。与1994年以来进行的四项全国性调查结果相比,该病原体产生β-内酰胺酶的患病率似乎在下降。
