Protective effect of P. parvulus 2.6p and 2.6NRp strains against V. anguillarum NB10[pOT11] zebrafish infection. (A) The experimental procedure. Before infection with V. angillarum, 4-days-old larvae were colonized during 18 h either by 2.6p with (2.6p^∗) or without β-glucan removal or by 2.6NRp strains. Also, as a control, a group of larvae was incubated in the absence of bacteria during 18 h prior infection. (B) Cumulative mortality due to Vibrio infection was analyzed at 24, 48, and 72 h after addition of the pathogen (hours post infection, hpi). Differences between conditions were evaluated at each point time. Statistical significances are represented by different letters that mean P ≤ 0.05.
