X‐cell gill disease obliterates the lamellar blood supply in the Antarctic teleost, Pagothenia borchgreviniki (Boulenger 1902)

Vascular corrosion casting methods were used to elucidate the pathological effects of X-cell disease on the blood supply to the gills of the Antarctic teleost, Pagothenia borchgrevinki (Boulenger, 1902). Afferent and efferent branchial arteries were patent in X-cell diseased fish; however, the blood...

Description
Summary:Vascular corrosion casting methods were used to elucidate the pathological effects of X-cell disease on the blood supply to the gills of the Antarctic teleost, Pagothenia borchgrevinki (Boulenger, 1902). Afferent and efferent branchial arteries were patent in X-cell diseased fish; however, the blood supply to the lamellae was markedly reduced or obliterated in areas in which there was a predominance of X-cells. The present authors believe that the tissue hyperplasia associated with X-cell disease results in the compression of the lamellar vascular bed which leads eventually to the occlusion of vessels.
