Abstract
Matched perianal swabs, rectal swabs, and faecal samples from a group of male homosexual patients attending a clinic for sexually transmitted disease were examined for the presence of group B streptococci (GBS). GBS recovery rates were as follows: perianal skin 31/115 (27%), rectal mucosa 18/72 (25%) and faeces 7/115 (6%). The recovery of GBS from faeces was similar to that obtained from faecal samples sent to the laboratory for routine investigation (5%). Although there was no difference in GBS recovery rates from rectal and perianal swabs, the latter did show heavier colonisation. These results suggest that gastrointestinal GBS carriage is mainly limited to the rectum and anal canal and that this may represent contamination from perianal skin.
摘要
对一组到性传播疾病诊所就诊的男性同性恋患者的配对肛周拭子、直肠拭子和粪便样本进行了B组链球菌（GBS）检测。GBS的检出率如下：肛周皮肤31/115（27%），直肠黏膜18/72（25%），粪便7/115（6%）。从粪便中检出GBS的情况与送至实验室进行常规检测的粪便样本相似（5%）。虽然直肠拭子和肛周拭子的GBS检出率没有差异，但后者的定植情况更严重。这些结果表明，胃肠道GBS携带主要局限于直肠和肛管，这可能是肛周皮肤污染所致。
