FIG 2 .

(A) Optical densities (OD₆₀₀) of cultures of V. anguillarum wild-type (wt) and QS mutant (ΔvanT and ΔvanO) strains in the presence or absence of phage KVP40 at an API of 1 were measured at 1-h intervals over a 10-h period of incubation. (B) Corresponding abundances of PFU per milliliter were quantified by plaque assay over a 10-h period of incubation in wild-type + KVP40, ΔvanT + KVP40, and ΔvanO + KVP40 cultures, respectively. Error bars represent standard deviations from all experiments carried out in duplicate.
