Genetic Factors Influence Serological Measures of Common Infections

"Our results demonstrate, for the first time for many of these pathogens (Chlamydophila pneumoniae, Helicobacter pylori, Toxoplasma gondii, hepatitis A virus, influenza A and B, cytomegalovirus, Epstein-Barr virus, herpes simplex virus (HSV)-1 and -2, human herpesvirus-6, and varicella zoster virus ), that individual genetic differences of the human host contribute substantially to antibody levels to many common infectious agents, providing impetus for the identification of underlying genetic variants, which may be of clinical importance."
