摘要 目的探讨流感嗜血杆菌在儿童患者中的耐药情况和β-内酰胺酶基因分型。方法收集2016年上海市儿童医院临床分离流感嗜血杆菌316株;纸片扩散法检测细菌对抗菌药物的耐药性,头孢硝噻吩纸片法检测细菌β-内酰胺酶表型,PCR方法对细菌β-内酰胺酶进行基因分型。结果 316株流感嗜血杆菌对甲氧苄啶/磺胺甲噁唑、氨苄西林、阿奇霉素、头孢呋辛和氨苄西林/舒巴坦耐药率分别为67.7%、52.2%、28.5%、26.9%和10.8%,对头孢噻肟、阿莫西林/克拉维酸敏感率均> 90%。41.1%(130/316)菌株检测到β-内酰胺酶基因,与表型一致,基因分型均为TEM-1型,未检测到ROB-1型。结论三代头孢和加酶抑制剂抗菌药物(头孢噻肟和氨苄西林/舒巴坦、阿莫西林/克拉维酸)对儿童感染流感嗜血杆菌有较好的抗菌活性;流感嗜血杆菌β-内酰胺酶基因分型均为TEM-1型。
