Fig. 4.

Multiple serotype colonisation of GBS from 96 rectovaginal/breastmilk/nasopharyngeal/rectal swabs originating from 21 mothers and 23 infants where serotype information was extrapolated from WGS. The circles represent the number of different serotypes cultured from each swab. The grey background represents maternal swabs, and the white background represent infant swabs. The swabs were taken at three different timepoints at day 0 (birth), day 6–9 and day 60–89 post-delivery of the infant. * = swab where there was at least one RAPD pattern that was not analysable by WGS. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
