Percentage of bacteria recovered following a 30-min exposure to either wild-type E. ictaluri or the EsaU mutant 65ST and a 60-min exposure to a killing dose of gentamicin. Values are the means ± standard errors of the results of three experiments. There were no significant differences between the results for the mutant and wild-type strains. ND, not determined.
