凝固酶阴性葡萄球菌（CoNS）被认为是医院内血流感染的最常见原因;然而，在没有全身感染体征和症状的情况下，这些菌种经常被指定为污染物。免疫功能低下的患者或植入假体的患者发生临床显著菌血症的风险增加。随着基质辅助激光解吸电离飞行时间质谱（MALDI-TOF MS）在临床实践中的出现，CoNS分离株鉴定的特异性得到了提高，并进一步阐明了未被识别的致病物种。培腾科费葡萄球菌是2002年首次发现的一种新的CoNS，由于生化鉴定的局限性，被认为是误诊为其他CoNS。S. pettenkoferi分离株;然而，有临床意义的S. Pettenkoferi菌血症，美国境内没有报告病例。我们提出了第一个已知的S。美国重症监护室的佩腾科费里
Coagulase-negative staphylococci (CoNS) are considered the most common cause of nosocomial bloodstream infections; yet, these species are frequently designated as contaminants in the absence of systemic signs and symptoms of infection. Immunocompromised patients or those with prosthetic devices are at increased risk for clinically significant bacteremia. With the advent of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) in clinical practice, there has been improved specificity of CoNS isolate identification and further elucidation of underrecognized pathogenic species. Staphylococcus pettenkoferi was a novel CoNS species first identified in 2002 and thought to be misdiagnosed as other CoNS due to limitations in biochemical identification. There is increasing identification of S. pettenkoferi isolates; however, there are limited case reports of clinically significant S. pettenkoferi bacteremia and no reported cases within the United States. We present the first known case of S. pettenkoferi from an American intensive care unit.
