Figure 2. – Histological section in Pagellus erythrinus gonads and intestine. A: Female normal gonads; B, C, E, F: Total replacement of the gonadal parenchyma by nematodes; relatively few and displaced oocytes (white arrows); B: Intense inflammation in direct contact with the worm (white asterisk); F: Gonad with haemorrhagic lesions and necrosis induced by P. filifomis (P); B, E: Secretion of melanin (white circles); D: Detail view of a parasite showing the nematode wall; G: Intestine of P. filiformis containing numerous erythrocytes. h: haemor- ragic lesion, i: intestine, n: necrosis), o: oocytes, p: parasite; w: parasite wall. Scale bars: A, B, C, E = 200 μm; F = 300 μm; D = 50 μm; G = 30 μm.
