Fig. 1From: Expression of free radicals by peritoneal cells of sheep during the early stages of Fasciola hepatica infectionPlasma levels of specific rFhCL1 IgG1 (a) and IgG2 (b). Each point represents mean values of antibody titre - log10 - (IgG1) and of optical density (IgG2) measured at 450 nm. Bars at each point represents tandard error. Immunisation with rFhCL1 developed a significant rise in the level of IgG1 isotype; dynamics of IgG1 in uninfected and infected sheep (Groups 1 and 2) shows a similar pattern, hence it is overlapped in the figure. Significant IgG2 production was detected only at 1 day post-infection (dpi) during the trialBack to article page
