C. elegans prefers prey patches not containing M. xanthus. Here we show worm locations relative to two circular prey patches after 25 h on plates where either (A) the patches contained either buffer or M. xanthus, (B) one patch contained E. coli or F. johnsoniae and the other patch contained the same with or without pre-mixed M. xanthus, or (C) one patch contained E. coli or F. johnsoniae and the other patch contained the other prey species with or without pre-mixed M. xanthus. Worms found on the plate but not in a patch are indicated in yellow, and worms that had left the plate by 25 h are indicated in grey. Bars are mean worm counts from three biological replicates. Raw data are shown in Figure S2. ‘F. john’ = F. johnsoniae, ‘M.xan_N’, ‘M.xan_S’ = M. xanthus strains N and S, respectively.
