医疗机构消毒监测样品马红球菌的分离鉴定及分布

Separated identification and distribution of medical institutions′ disinfection monitor sample horse-rhodococcus

目的:探讨医疗机构消毒监测中马红球菌的分离鉴定与分布。方法:将常规监测样品培养72 h产生色素的菌落分纯后进行生化鉴定。结果:马红球菌的鉴别要点是不发酵任何糖醇、CAMP和触酶阳性、H2S和动力阴性、菌落呈黏液状、产生色素、生长缓慢。结论:细胞介导免疫受损病人病房相关消毒监测应将马红球菌纳入必检项目,只要熟练掌握该菌的生物学性状则分离鉴定并不困难。

Objective： To investigate the separated identification and distribution of medical institutions′ disinfection monitor sample Horse-Rhodococcus rhodococcus.Methods：Cultivate samples of conventional monitoring within 72 hrs of the colony produce pigment after hours of pure,then processes biochemical identification.Results：The main points of Horse-Rhodococcus rhodococcus Identification are non ferment any suger alcohols,CAMP andcatalase-positive,H2S and power negative,the mucus-like colony,produce pigment and glow slowly.Conclusion：The cell-mediated immune damage patients′ wards should be related with the disinfection monitor.Detected items must be included Horse-Rhodococcus rhodococcus.just master the biological characteristics of bacteria,then it is not difficult about the separated identification.
