Streptococci have been isolated which may be identified in serological tests as belonging to Lancefield group G, but in fact belong to group D. Twenty-two cultures with this property were obtained from four countries; they included Streptococcus bovis and Streptococcus durans as well as Streptococcus faecalis. Selected strains were studied in serological tests and cross-absorption procedures, in which it was found that the group G reaction given by these isolates is due to an epitope with at least partial identity with reference group G antigen. Identification of an enterococcus as a group G streptococcus could lead to erroneous and ineffective chemotherapy. Antibiotic sensitivity testing of streptococcus group G isolates should be a routine procedure, and bile-aesculin and salt-tolerance testing of these isolates would be a wise precaution.
已分离出一些链球菌，这些链球菌在血清学检测中可能被鉴定为属于兰斯菲尔德G组，但实际上属于D组。从四个国家获得了22株具有这种特性的培养物；它们包括牛链球菌、耐久链球菌以及粪肠球菌。对选定的菌株进行了血清学检测和交叉吸收程序研究，结果发现这些分离株产生的G组反应是由于一个与参考G组抗原有至少部分相同性的表位。将肠球菌鉴定为G组链球菌可能会导致错误且无效的化疗。对G组链球菌分离株进行抗生素敏感性测试应作为常规程序，对这些分离株进行胆汁七叶苷和耐盐性测试将是一项明智的预防措施。
