*The frequencies in columns sharing the same upper case letter are not significantly different at P<0.00091 (multiple comparisons with Bonferroni corrections). The expected (exp) and observed (obs) co-infection frequencies that share the same lower case letter are not significantly different at P<0.05 (nonparametric tests χ2).
