Figure Lengend Snippet: Marker expression and morphological analysis of the central cornea region of ISAV‐infected Atlantic salmon. Immunohistochemistry for IgM expression showing the presence of IgM (red colour) in the central corneal epithelium (brackets) of non‐infected (A) and ISAV‐infected Atlantic salmon (B). Increased levels of IgM staining in the central corneal stroma of ISAV‐infected animals are shown in the boxed area. The characteristic morphological cellular layering of the central corneal epithelium indicated with black arrows in non‐infected Atlantic salmon (A) does not appear as prominant in the ISAV‐infected animals (B). A negative control for anti‐IgY‐AP is shown in the inset in (B). Immunohistochemistry for Sox6 showing negative results in non‐infected Atlantic salmon (C). Cells in the central corneal epithelium of ISAV‐infected Atlantic salmon were positive for Sox6 (D), with the highest signal being detected near Bowman's membrane (Bm). A negative control for anti‐IgG2b‐AP is shown in the inset in (D). Sox9 was negative within non‐infected Atlantic salmon (E) but positive in some cells in ISAV‐infected Atlantic salmon (F) and was localized near the outer central corneal epithelium (arrows in F). The upper right inset in (F) shows a magnified view of the cell boxed in black in (F). The bottom left inset in (F) shows a negative control on the same tissue for anti‐rabbit IgG‐AP. Immunohistochemistry for CD10 showed central corneal stromal staining in what appeared to be keratocytes in both non‐infected (G) and ISAV‐infected (H) salmon. A negative control on the same tissue for anti‐rabbit IgG‐AP is shown in the inset in (H). Giemsa and Herovichi histological stains highlighted the change in organization of the central corneal epithelium in healthy (I and K, bracket) versus ISAV‐infected (J, L) salmon. 400X. Scale bar subdivisions equal 10 μm.
