Neutralizing titers of maternal and infant sera. CMV neutralizing capacity of maternal third trimester sera and infant cord sera were tested using an in-vitro neutralizing assay, without or with guinea pig complement, and the IC50 titer was calculated for each sample. The IC50 titers without complement (dotted lines) and with complement (solid lines) were compared to anti-gB and anti-gM/gN titers in maternal (A,C) and infant (B,D) sera. (A,B) The x-axis range reflects anti-gB titers ranging from 1:200-1:12800. (C,D) The x-axis range reflects anti-gM/gN titers ranging from 0–1:800 (A–D). For each correlation plot, a single circle/square may represent more than one sample with the antibody titer/neutralizing IC50 titer shown in each graph.
