Bacterial dissemination in the fish tissues. Tilapia were infected with the same dose of TX01, TX01ΔcadA, TX01ΔcadB, TX01ΔcadBA, TX01ΔcadAC, and TX01ΔcadBC. The recoveries of bacteria in spleen (A) and kidney (B) were determined by plate counting at 24 and 48 h post-infection. Data are presented as means ± SEM (N = 3). N, the number of times the experiment was performed. **, P < 0.01.
