Abstract

A semicomatose 34-year-old man had fever, heart murmur, and multiple gangrenous lesions. Several blood cultures were negative. Cultures of the heart valve grew beta-haemolytic streptococcus group B. The organism was seen in buffy-coat examination of the venous blood. The gas-liquid chromatogram of the serum was different from those of normal controls and of patients with invasive candida infection; it closely mimicked the one obtained from the organism itself. These studies promise to be valuable diagnostic adjuncts.

摘要

一名34岁的半昏迷男子出现发热、心脏杂音和多处坏疽性病变。多次血培养均为阴性。心脏瓣膜培养物中生长出B组β溶血性链球菌。在静脉血的血沉棕黄层检查中发现了该病原体。血清的气液色谱图与正常对照以及侵袭性念珠菌感染患者的不同;它与从病原体本身获得的色谱图极为相似。这些研究有望成为有价值的诊断辅助手段。
