Figure 1: TEM demonstrating localised bacterial populations in close proximity and association with the epithelial brush border in the anterior intestine of rainbow trout. Scale bars 2 μm (except B inset: 5μm). TEM showing V. anguillarum-like cells (A; probiotic fed fish exposed to V. anguillarum) and P. acidilactici-like cells (B; probiotic fed fish exposed to P. acidilactici) in the lumen and in close association with microvilli. Inset figures show respective cell morphologies of known samples of the bacterial strains used within the assays.
