Group B beta-hemolytic streptococci (GBS) were isolated from 242 patients at Howard University Hospital during a seven-month period. The source of the majority, 236, was the genital tract of women. In six instances, the organism was cultured from various sites in neonates born of mothers harboring GBS in their birth canals. All of the patients were black. The study indicates that the frequency of colonization of the genital tract by GBS in black females is higher than that reported for white women. Although the sample is small, there appears to be a correlation between genital tract colonization of GBS in mothers and colonization in their affected newborns.
在七个月的时间里，从霍华德大学医院的242名患者中分离出了B组β溶血性链球菌（GBS）。其中大多数（236例）的感染源是女性生殖道。有6例是从出生时母亲产道中携带GBS的新生儿的不同部位培养出这种病菌的。所有患者均为黑人。该研究表明，黑人女性生殖道被GBS定植的频率高于报道的白人女性。尽管样本量较小，但母亲生殖道GBS定植与其受影响新生儿的定植之间似乎存在关联。
