Abstract

In a 4 year prospective study of "viridans" or non-groupable streptococci 100 clinically significant strains were isolated. Strains were defined as significant when found in two or more samples of blood cultures, or when seen on Gram staining together with inflammatory reaction. Fifty-two strains were speciated by 10 physiological characteristics. In 42 cases additional tests were performed. Only 16 isolates were unidentifiable by the techniques used. Sources of isolates included purulent lesions (53%) (mainly S. milleri and S. mitior); endocarditis (27%) (S. bovis I, S. sanguis, S. mutans, S. bovis II) and urinary tract infections (10%) (S. bovis II, S. milleri).

摘要

在一项针对“草绿色”或不可分组链球菌的4年前瞻性研究中，分离出了100株具有临床意义的菌株。当在两份或更多份血培养样本中发现菌株，或在革兰氏染色中与炎症反应同时出现时，这些菌株被定义为具有临床意义。通过10种生理特征对52株菌株进行了分类。在42例病例中进行了额外检测。使用现有技术仅16株分离菌无法鉴定。分离菌的来源包括化脓性病变（53%）（主要是米勒链球菌和缓症链球菌）；心内膜炎（27%）（牛链球菌I、血链球菌、变形链球菌、牛链球菌II）和尿路感染（10%）（牛链球菌II、米勒链球菌）。
