Infection proxies. Plasma antibody titres against A Ascarids, and B Histomonas meleagridis, as well as C the plasma concentration of the acute-phase protein AGP, and D the PCR quantification of histomonads per total daily faeces (HPD) were measured. Each dot in the boxplot represents an individual bird, with uninfected birds represented by orange dots and infected birds represented by blue dots. The lower and upper ends of the box represent the 25th and 75th quantiles, respectively. Statistical analyses are based on log-transformed data [log(y + 1)], while visualisation is based on untransformed data. (n infected birds = 18, n birds in control = 12).
