FIG 5.

ESR1 competitive colonization defect is not observed in ES114-L. Squid competition experiments in which ES114 and the indicated strain were coinoculated with newly hatched E. scolopes squid for 3 h, with a total colonization time of 48 h. Shown are animals from two replicates for each experiment. Single-sample t tests were conducted to identify significant deviations from neutral. The ES114-L results were nonsignificant (n.s.) (P = 0.36), whereas ESR1 exhibited significant results (P = 0.001 [***]).
