临床分离的醋酸钙鲍曼复合不动杆菌耐药性分析

目的:研究无锡市第四人民医院和无锡市第三人民医院临床分离的醋酸钙鲍曼复合不动杆菌的耐药情况及其临床分布特点.方法:收集并分离临床来源的35株醋酸钙鲍曼复合不动杆菌,观察并记录临床分布,并用琼脂二倍稀释法测定抗菌药物对醋酸钙鲍曼复合不动杆菌的MIC值.结果:临床分离的35株醋酸钙鲍曼复合不动杆菌ICU感染居多,占42.86%,老年男性居多,主要来源于痰,占88.57%.醋酸钙鲍曼复合不动杆菌对氨苄西林、哌拉西林、头孢唑林、呋喃妥因的耐药率均为100%;对氨苄西林/舒巴坦、阿莫西林/克拉维酸、头孢米诺、头孢匹胺、氨曲南和庆大霉素的耐药率＞90%;对替卡西林/克拉维酸、头孢曲松、头孢吡肟、环丙沙星、左氧氟沙星、复方磺胺甲噁唑的耐药率≥80%;对哌拉西林/他唑巴坦、头孢他啶、阿米卡星、妥布霉素、加替沙星的耐药率＞50%;对亚胺培南、美罗培南、头孢哌酮/舒巴坦的耐药率相对较低,分别为23.53%、11.43%、11.43%.结论:醋酸钙鲍曼复合不动杆菌对美罗培南、亚胺培南、头孢哌酮/舒巴坦较敏感,临床医生应根据药敏结果和患者自身情况合理用药.
