克雷白氏菌在导致医院内感染的革兰氏阴性杆菌中占有显著的地位。1965年Maiz-tegui等发现在波士顿医院里,克雷白氏菌是引起革兰氏阴性杆菌菌血症的第二个大菌群。本文是在一个综合医院内对克雷白氏菌血症的临床和流行病学的调研报告。材料收集自1972年7月至1973年10月期间在Harbor综合医院的41名克雷白氏菌血症患者。除2例初生婴儿和1例成人为尸检取心血培养证实外,所有阳性血标本均在生前取得。取得的克雷白氏菌在临床微生物实验室按Edward和Ewing系统方法进行鉴定,并按Bauer等方法作了药敏试验。菌株在亚 Klebsiella plays a prominent role in gram-negative bacilli that cause nosocomial infections. In 1965, Maiz-tegui et al. Found that in Boston Hospital, Klebsiella was the second largest group of bacteria causing gram-negative bacteremia. This article is a clinical and epidemiological investigation of Klebsiella bacteremia in a general hospital. Materials were collected from 41 Klebsiella bacteremia patients at the Harbor General Hospital from July 1972 to October 1973. Except for 2 newborn infants and 1 adult confirmed by autopsy for blood culture, all positive blood samples were obtained before their birth. The obtained Klebsiella was identified in the clinical microbiology laboratory by the method of Edward and Ewing system, and drug susceptibility testing was made according to Bauer et al.
