Fig. 1From: Antibody response of definitive hosts against antigens of two life stages of the neuropathogenic schistosome Trichobilharzia regenti The course of specific IgY response against T. regenti cercarial antigens in ELISA. SD - domestic ducks exposed to single dose of 1500 of cercariae; RD - domestic ducks exposed repeatedly to 1500 cercariae; SM - mallards infected by single dose of 1500 cercariae at the age of maturity of antibody response; RM - mallards exposed repeatedly to 1500 cercariae; Ctrls - control non-infected animals. Cutoff calculated for 95 % confidence level is drawn by a dot-and-dash line for each time point. Data are the mean ± SEM for at least five individuals. Statistical significances (***P < 0.001) were confirmed by random effects ANOVABack to article page
