Strong Correspondence of the Vaginal and Rectal Load of Group B Streptococci in Pregnant Women

Figures

Figure 1. GBS bacterial load, determined by qPCR, for the vaginal, rectal and vaginorectal swabs respectively, for each woman positive for at least one swab. RVS: Rectal vaginal study.

Figure 2. Log 10 (cells/mL) concentration of Group B streptococci in the vagina (V) versus the rectum (R). RV D pos: vaginorectal swab is positive for GBS by means of qPCR; RV D neg: vaginorectal swab is negative for GBS by means of qPCR. Blue lines indicate Cq cut off values. Samples with values below these lines are considered qPCR negative. For these samples, reliable quantification was not possible and values indicated are presumptive. Samples with identical values are represented by only one dot.
