Seasonality of Angiostrongylus vasorum and Crenosoma vulpis infections. Each bar represents the mean monthly prevalence (calculated for 2003–2015) of A. vasorum (red bars) and C. vulpis (blue bars). Whiskers show 95% confidence intervals. Different letters above the whiskers indicate statistically significant differences between the proportions of positive and negative results (pairwise Fisher’s test). The horizontal bars represent stages of the life-cycle refer to a hypothesis to explain the seasonal pattern of diagnosed A. vasorum and C. vulpis infections in domestic dogs
