A comparative analysis of the performance of the new selective chromogenic CHROMagar™-Serratia culture medium for detection and isolation of Serratia marcescens was undertaken. A total of 134 clinical isolates (95 S. marcescens with and without carbapenemase production and 39 non-S. marcescens isolates) and 96 epidemiological samples (46 rectal swabs and 50 from environmental surfaces) were studied. Diagnostic values when compared with CHROMagar™-Orientation medium were 96.8% sensitivity, 100% specificity, 100% positive predictive value and 88.5% negative predictive value. In conclusion, CHROMagar™-Serratia shows an excellent ability for differentiation of S. marcescens among clinical isolates and in environmental samples.
对新型选择性显色 CHROMagar™-Serratia 培养基用于检测和分离粘质沙雷氏菌的性能进行了比较分析。共研究了 134 株临床分离株（95 株产碳青霉烯酶和不产碳青霉烯酶的粘质沙雷氏菌和 39 株非粘质沙雷氏菌分离株）和 96 份流行病学样本（46 份直肠拭子和 50 份环境表面样本）。与 CHROMagar™-Orientation 培养基相比，其诊断值的灵敏度为 96.8%，特异性为 100%，阳性预测值为 100%，阴性预测值为 88.5%。总之，CHROMagar™-Serratia 培养基在临床分离株和环境样本中对粘质沙雷氏菌的分离具有极好的区分能力。
