E. coli OP50 and S. epidermidis avoidance behavior in N2 and CB4856 isolates. A Bacterial lawn avoidance assay. L4 worms were washed and then placed at the periphery of a bacterial lawn. At 1-hr and 24-hr timepoints the percentage of worms occupying the lawn was calculated. B-C Percentage of N2 and CB4856 animals on a lawn of E. coli OP50 (B) or. S. epidermidis (C). In each experiment, 20 worms were placed on NGM plates and the number of worms on the bacterial lawn was recorded at regular intervals. Data presented as mean and standard deviation of five independent experiments.***, p < 0.001; NS, p > 0.05
