目的：了解武汉地区儿童分离鲍曼不动杆菌对常见抗生素的耐药性变迁。方法：使用K-B法对2006~2008年期间武汉市儿童医院分离的非重复的679株鲍曼不动杆菌株进行抗菌药物敏感试验，参照美国临床实验室标准化委员会(CLSI)2008年版规则判断结果。结果：与2006年相比，2007年分离的鲍曼不动杆菌对哌拉西林/他唑巴坦、头孢吡肟、头孢他啶的非敏感率显著增加（P<0.05）。而与2007年相比，2008年分离菌对哌拉西林/他唑巴坦、头孢吡肟、头孢哌酮/舒巴坦、头孢他啶、亚胺培南、美洛培南的耐药率均显著增加，差异有统计学意义（P<0.05）。结论：武汉地区儿童分离鲍曼不动杆菌对β-内酰胺类抗生素的非敏感率2006~2008年期间逐年增加。［中国当代儿科杂志，2010，12（8）：613-615］

OBJECTIVE: To investigate the variance of antibiotic resistance of Acinetobacter Baumanii isolated from children in Wuhan between 2006 and 2008. METHODS: Bacterial susceptibility testing was carried out by the Kirby-Bauer method in 679 strains of Acinetobacter Baumanii isolated in Wuhan Children’s Hospital between 2006 and 2008. The results were assessed according to the guidelines of the Clinical and Laboratory Standards Institute (2008). RESULTS: The nonsusceptible rates of Acinetobacter Baumanii to ceftazidime, cefepime and piperacillin/sulbactam increased significantly in 2007 compared with those in 2006 (P<0.05). By comparing the results of 2007, it was suggested that the nonsusceptible rates of Acinetobacter Baumanii to ceftazidime, cefepime, piperacillin/sulbactam, cefoperazone/sulbactam, imipenem and meropenem increased significantly in 2008 (P<0.05). CONCLUSIONS: The nonsusceptible rates of Acinetobacter Baumanii to β-lactam antibiotics in children from Wuhan increased significantly year by year between 2006 and 2008.［Chin J Contemp Pediatr, 2010, 12 (8):613-615］
