The genus Citrobacter was recently determined to contain 11 genetically distinct species. In addition, the International Committee on Systematic Bacteriology no longer recognizes C. diversus and has, instead, validated the name C. koseri in its place. The 11 species are C. freundii, C. koseri, C. amalonaticus, C. farmeri, C. youngae, C. braakii, C. werkmanii, C. sedlakii, and three unnamed groups, genomospecies 9, 10, and 11. To determine the ease with which some identification systems could respond to these changes, we evaluated five systems for their potential ability to recognize current species in the genus Citrobacter. A simple dichotomous key using conventional biochemicals is presented that may be helpful to presumptively identify Citrobacter strains.
柠檬酸杆菌属最近被确定包含11个基因不同的种。此外，国际系统细菌学委员会不再认可异型柠檬酸杆菌，而是确认了科氏柠檬酸杆菌这一名称取而代之。这11个种分别是弗氏柠檬酸杆菌、科氏柠檬酸杆菌、无丙二酸柠檬酸杆菌、法氏柠檬酸杆菌、杨氏柠檬酸杆菌、布拉氏柠檬酸杆菌、韦氏柠檬酸杆菌、塞氏柠檬酸杆菌以及三个未命名的菌群，即基因种9、10和11。为了确定某些鉴定系统适应这些变化的难易程度，我们评估了五种系统识别柠檬酸杆菌属当前菌种的潜在能力。本文提供了一个使用传统生化指标的简单双歧检索表，可能有助于初步鉴定柠檬酸杆菌菌株。
