Figure 1.

Distribution of bat groups according to sex, age class and reproductive stages, and temporal infection dynamics in two maternity colonies of (a) M. natalensis and (b) R. aegyptiacus. Sampling sessions are denoted by a star on the x-axis. The continuous lines represent the prevalence of infections modelled by GLM and the shaded area the 95% confidence interval. Curves were produced using a loess smoother. Observed prevalence rates at each sampling session are represented by dots with the 95% confidence interval and the number of tested samples indicated. Elements have been moved slightly on the x-axis to avoid superimposition.
