Comparison of the total number of Cryptosporidium present in Cryptosporidium- exposed biofilms and biofilm-free control systems. Graph showing the total number (mean ± standard error) of Cryptosporidium (retained in biofilm + effluent) determined at the end of each experiment (one, three and six day) for Cryptosporidium- exposed biofilms (black bar) (n = 3) and Cryptosporidium only (biofilm-free) control systems (white bar) (n = 3), as determined using a DNA-based qPCR approach. Significance was determined by a two-way ANOVA analysis with a post hoc test of significance (* P < 0.001).
