Figure 2

(A) Section of the head of a 21 dph larva with cysts (arrows) in gills and skin. (B) A typical large cyst in the gills of a 21 dph infected larva with particulate appearance, and a small one below it, are visible. (C) Section of the head of an infected larva 28 dph, with extensive and multiple cysts in the epithelium of the skin, mouth and gills. (D) Higher magnification of the gill lamellae from (C) showing bacterial-sized particles within cysts. (E) An empty inclusion from a 21 dph larva with freed bacteria (*) attaching to the next filament. There is also a newly formed small inclusion (arrow) at the base of the lamella. Scale bars represent: (A,C) 200 μm, (B) 10 μm, (D,E) 20 μm.
