Number of isolates determined to be greater than 49.6% Bd-inhibitory are given out of total number of isolates within each genus. Mean level of Bd-inhibition displayed by genus and level of urbanization (U = urban, S = suburban, E = exurban).
†
Denotes significant difference (p < 0.05) from Bacillus (non-inhibitory).
