Analysis of the Mycoplasma genitalium MgpB Adhesin to Predict Membrane Topology, Investigate Antibody Accessibility, Characterize Amino Acid Diversity, and Identify Functional and Immunogenic Epitopes.

ABSTRACT: Mycoplasma genitalium is a sexually transmitted pathogen and is associated with reproductive tract disease that can be chronic in nature despite the induction of a strong antibody response. Persistent infection exacerbates the likelihood of transmission, increases the risk of ascension to the upper tract, and suggests that M. genitalium may possess immune evasion mechanism(s). Antibodies from infected patients predominantly target the MgpB adhesin, which is encoded by a gene that recombines with homologous donor sequences, thereby generating sequence variation within and among strains. We have previously characterized mgpB heterogeneity over the course of persistent infection and have correlated the induction of variant-specific antibodies with the loss of that particular variant from the
