We aimed at analyzing the seroprevalence of cytomegalovirus infection (CMV) and to assess particular aspects of the related immunological profile among blood donors in the State of Bahia, Brazil. Immunoassays were performed to detect anti-CMV IgG and IgM antibodies and the anti-CMV IgG avidity was evaluated. The methodology used was Enzyme Linked Immuno Sorbent Assay (ELISA) with results being confirmed by chemiluminescence. Reactivity to CMV was compared between genders and age groups. Among the 636 healthy blood donors tested, 428 (67.3%) were men and 208 (32.7%) were women. The overall seroprevalence of CMV was 87.9%; seroprevalence was statistically higher in women (94.7%) than in men (84.6% - p
