INTRODUCTION
Staphylococcus pettenkoferi was originally isolated and described by Trülzsch et al (2002). In this study, we characterized two isolates of this newly described species.
METHODS
Blood cultures were initially processed using the BacT/ALERT(R) device, and the isolates were initially characterized using the Vitek2 identification system.
RESULTS
The initial characterization revealed slow-growing Gram-positive cocci that formed opaque colonies on sheep blood agar. Other phenotypic/genotypic tests were performed.
CONCLUSIONS
We would like to emphasize that this new staphylococcus species is phenotypically similar to other CoNS, especially S. auricularis. This could potentially lead to misidentification of these uncommon species.
简介
葡萄球菌 pettenkoferi 最初由 Trülzsch 等人（2002 年）分离并描述。在这项研究中，我们对这一新描述的物种的两个分离物进行了特征描述。
方法
血液培养最初使用 BacT/ALERT（R）设备进行处理，分离物最初使用 Vitek2 鉴定系统进行鉴定。
结果
初始特征显示缓慢生长的革兰阳性球菌，在绵羊血琼脂上形成不透明的菌落。进行了其他表型/基因型测试。
结论
我们想强调的是，这种新的葡萄球菌在表型上与其他凝固酶阴性葡萄球菌相似，尤其是 S. auricularis。这可能导致这些不常见的物种被错误鉴定。
