Pairwise antagonism counts

Matrix of raw data collected during pairwise antagonism tests. Counts of positive antagonistic interaction of test isolate against sensitive isolate out of six total replicates performed per pair.

Schematic of antagonism methodology and photo

Flowchart of experimental methodology used to generate antagonism counts. Any size clearing of indicator isolate was interpreted as antagonism. Isolates were replicated twice on each plate, and each plate was replicated three times, for a total of six replicates. The location of isolates on the left half of the plate were randomized for placement on the right side of the plate in an attempt to control for local environmental effects on phenotype expression.
