Fig. 2From: Phenotypic changes in group B streptococci grown in the presence of the polyols, erythritol, sorbitol and mannitolExpression of PGK on the surface of GBS grown in the presence of polyols. GBS-S19 was grown for 20 h in TH broth supplemented with polyols indicated. The quantity of GBS-PGK expressed on the bacterial surface was assayed using polyclonal antibodies against GBS-PGK. Each experiment was performed in triplicate. The bars represent the average A450 values compared with GBS grown in THB without addition of polyols (0%). The A450 values were compared with the value obtained from (0%) to determine statistical significance; an asterisk (*) indicates statistical significance (p < 0.05)Back to article page
