The prevalence of antibiotic resistance among bacteria responsible for severe infections in childhood is increasing. In H. influenzae, clinically relevant resistance to ampicillin and chloramphenicol is caused by plasmid mediated enzymatic drug inactivation whereas penicillin resistant pneumococci emerge as the result of alterations in their penicillin binding proteins. In N. meningitidis both mechanisms have recently been implicated in penicillin resistance. Although antibiotic resistant H. influenzae, S. pneumoniae and, to much less extent, N. meningitidis have a widespread distribution, marked geographical variations exist in their prevalence. In areas where these drug resistant bacteria are reported, cefotaxime or ceftriaxone should be used for the empiric treatment of suspected severe bacterial infections in childhood.
导致儿童严重感染的细菌中抗生素耐药性的发生率正在上升。在流感嗜血杆菌中,对氨苄西林和氯霉素的临床相关耐药性是由质粒介导的酶促药物失活引起的,而青霉素耐药肺炎球菌则是由于其青霉素结合蛋白发生改变所致。在脑膜炎奈瑟菌中,这两种机制最近都与青霉素耐药性有关。尽管抗生素耐药的流感嗜血杆菌、肺炎链球菌以及程度较轻的脑膜炎奈瑟菌分布广泛,但它们的发生率存在显著的地理差异。在报告有这些耐药菌的地区,应使用头孢噻肟或头孢曲松对疑似儿童严重细菌感染进行经验性治疗。
