医院外科术后感染的细菌分布及耐药性分析

目的了解我院外科术后感染病原菌的分布及耐药性.方法肉汤稀释法,应用英国先德微生物分析系统对本院外科感染标本进行细菌鉴定及药敏分析.结果肠杆菌属细菌为主要的创面感染菌,占总数的51.5%.环丙沙星、氨曲南、亚胺培南对肠杆菌科细菌呈现高度的敏感性;阳性珠菌感染26.3%,其中凝固酶阴性葡萄球菌(CNS)的感染明显增多,说明CNS已成为重要的机会致病菌.结论本组资料对外科术后感染的治疗和抗菌药物的选用具有一定的参考价值.

The bacterial distribution and resistance analysis of postoperative infection in hospital

Objective To investigate the bacterial distribution and analyze the resistance of postoperative infection in hospital. Methods Broth dilution method is employed to identify bacteria and test antimicrobial susceptibility of the infective samples from surgical infective patients by the Sensititre microbic analytical system. Results The main pathogenic bacterium of the raw surface is Cedecea, which is of 51.5%, and most of them are sensitive to ciprofloxacin, aztreonam, imipenem. 26.3% of the total is G+ coccobacteria. What's more, the infection of coagulase-negative staphylococci(CNS) is increasing obviously. This indicates that the CNS is an important opportunity pathogenic bacteria. Conclusions The data will be useful for reasonably choosing antimicrobial agents in the treatments of postoperative infections caused by pathogenic bacteria.
