Fig. 5. Average frequencies (mean ± standard error) that isolates from Red Run–Bear Creek (Sites 9 and 10), lower Clinton River (Sites 3, 4, 5, and 6), and Metro and Memorial beaches (Sites 1 and 2) were assigned to host categories of human, birds, pets, or farm animals on seven sampling dates. Indicated percentages are out of the isolates that could be assigned by reference to known source isolates, leaving out isolates of uidA1 and alleles not observed in reference fecal isolates. Two-way analysis of variance (ANOVA), hosts, p < 0.001; sites within hosts, p < 0.02; *, significantly different from beaches within a particular host; and #, significantly different from humans within that collection site (Student–Newman–Keuls pairwise comparisons, p < 0.05).
