Ninety-five cultures of group JK bacteria isolated from clinical specimens were characterized morphologically and biochemically. The microorganisms were isolated primarily from blood cultures. The bacterial cultures produced positive reactions when tested for catalase, Tween hydrolysis, and carbohydrate fermentation. Glucose and galactose were fermented by more than 90% of the organisms. Gas-liquid chromatography of trimethylsilyl derivatives of whole-cell hydrolysates of some of the group JK cultures yielded nearly identical elution profiles. The group JK microorganisms were susceptible to vancomycin but were resistant to most of the other 17 antimicrobial agents tested. A method is presented for differentiating the group JK microorganisms from other similar bacteria encountered in clinical specimens. Although these bacteria rarely occur in clinical specimens, they are capable of producing fatal infections (endocarditis and sepsis) in humans.
对从临床标本中分离出的95株JK菌群细菌进行了形态学和生物化学特征分析。这些微生物主要从血培养物中分离得到。对这些细菌培养物进行过氧化氢酶、吐温水解和碳水化合物发酵检测时，均产生阳性反应。超过90%的菌株能发酵葡萄糖和半乳糖。对部分JK菌群培养物的全细胞水解产物的三甲基硅烷基衍生物进行气液色谱分析，得到了几乎相同的洗脱图谱。JK菌群微生物对万古霉素敏感，但对其他17种受试抗菌药物大多耐药。本文介绍了一种将JK菌群微生物与临床标本中遇到的其他类似细菌区分开来的方法。尽管这些细菌在临床标本中很少出现，但它们能够在人类中引发致命感染（心内膜炎和败血症）。
