The incidence of and average time to detection for Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, and Kingella (HACEK) bacteria in blood cultures with standard incubation and the utility of extended incubation of blood culture bottles were reviewed at four tertiary care microbiology laboratories. HACEK organisms were isolated from 35 (<0.005%) of 59,203 positive blood cultures. None of 407 blood cultures with extended incubation grew HACEK or other bacteria. Bacteremia from HACEK bacteria is rare, and extended incubation of blood cultures to recover HACEK bacteria is unnecessary.
在四个三级医疗微生物实验室,对采用标准培养法的血培养中嗜血杆菌属、放线杆菌属、心杆菌属、艾肯菌属和金氏杆菌属(HACEK)细菌的发生率及平均检测时间,以及血培养瓶延长培养的效用进行了回顾性研究。在59203份阳性血培养中,有35份(<0.005%)分离出HACEK微生物。407份进行延长培养的血培养中,没有一份培养出HACEK或其他细菌。由HACEK细菌引起的菌血症很罕见,延长血培养时间以分离出HACEK细菌并无必要。
