Fig. 3From: Combined genetic variants of human cytomegalovirus envelope glycoproteins as congenital infection markersGlycoprotein B, N and O genotype distributions in congenitally and post-natally infected children. The overall distributions of gB, gN and gO genotypes are shown in the pie charts of panels a, b and c, respectively; the subdivision of gB, gN and gO variants among congenitally and post-natally infected children is displayed in the adjacent bar charts. The number of subjects infected with the specific genotypes and the related percentages are indicated at the top of each barBack to article page
