Serovar D induced significantly higher plasma (p < 0.05) and vaginal (p < 0.05) IgG levels as compared to serovar H. Although no quantitative differences between the IgA responses following infection with either serovar D and H were observed in the vaginal secretions of animals with detectable levels of antibody, a significant difference was observed in the frequency of IgA positive vaginal secretions from serovar H and D infected animals prior to reinfection (11/24 for H vs 21/24 for D, p < 0.01, data not shown). Here, CD79A is linked to infection.
