Serological profiles of serum antibody reactivity to Merkel cell polyomavirus (MCPyV) VP1 S (A, D), VP2 F (B, E) peptides and for combined S and F peptides (C, F) in age- and gender-stratified elderly subjects (ES). Immunologic data are from age- and gender-stratified ES, and results are reported as optical density (OD) value readings at λ 405 nm for serum samples assayed in indirect ELISA. In the scatter dot plot, each dot represents the dispersion of ODs for each sample. The median is indicated by the line inside the scatter plot with the interquartile range (IQR) in age-stratified ES, i.e., 66–70 (n = 40), 71–75 (n = 46), 76–80 (n = 57), 81–85 (n = 47), and 86–100 (n = 36) years and in gender-stratified ES, i.e., males (n = 106) and females (n = 120). No statistically significant differences in MCPyV seroreactivity were determined among age-/gender-stratified groups (p > 0.05).
