Abstract

Streptococci of Lancefield group D were isolated from 52.2% of pharyngeal, 55.5% of urethral, 56.6% of endocervical, and 75.4% of ano-rectal specimens. Seventeen phages isolated from sewage and urogenital specimens were selected for phage typing. Four of these lysed only the strains of Streptococcus faecalis and its variety liquefaciens. Another six phages lysed only the strains of Streptococcus faecium and its variety durans. With the help of seven bacteriophages, 346 of 384 (90.1%) strains of S. faecalis and its variety liquefaciens could be classified into 27 types. Similarly, with the help of 10 other bacteriophages, 97 of 117 (82.9%) strains of S. faecium and its variety durans could be grouped into 22 types. In 72 of 87 (82.7%) cases, similar phage types were obtained at different culture sites of the same individual.

摘要

从52.2%的咽拭子标本、55.5%的尿道标本、56.6%的宫颈内膜标本和75.4%的肛门直肠标本中分离出兰斯菲尔德D群链球菌。从污水和泌尿生殖系统标本中分离出17种噬菌体用于噬菌体分型。其中4种仅能裂解粪链球菌及其液化变种菌株。另外6种噬菌体仅能裂解屎肠球菌及其耐久变种菌株。借助7种噬菌体,384株粪链球菌及其液化变种中的346株(90.1%)可分为27个型别。同样,借助另外10种噬菌体,117株屎肠球菌及其耐久变种中的97株(82.9%)可分为22个型别。在87例中的72例(82.7%)中,同一个体不同培养部位获得了相似的噬菌体型别。
