Kinetics of histamine in intestinal fluids from small intestine during early T. spiralis infection. Histamine concentrations were determined using a commercial ELISA kit. Results are expressed as the concentration mean ± SD from 5 rats/dpi and 5 control rats. Data were analysed by one-way ANOVA followed by Tukey’s multiple comparisons test (nlme and multcomp packages, respectively; α = 0.05). Asterisks (*) represent significant differences between infected and non-infected animals: *P < 0.05, **P < 0.01, ***P < 0.001. Bars indicate significant differences among days. Numerals (#) above bars indicate significant differences between days: ^##P < 0.01
