Increasing the detection rate of group B streptococcal carriers by non-selective cervico-vaginal culture accompanied with the selective vagino-anorectal one.

摘要

It has been previously well defined that selective vagino-anorectal culture is required for detection of group B streptococcal (GBS) carriage. We interestingly observed that in 5.74% of carriers, GBS were recovered only from cervico-vaginal samples inoculated onto nonselective human blood agar, without recovery from vagino-anorectal samples inoculated to four selective media.
