Histological changes in gills, kidney and liver were used to evaluate the health of the Neotropical fish species Prochilodus lineatus, subjected to in situ tests for 7 days in a disturbed urban stream and in a reference site, during winter and summer. In fish caged in the urban stream the most common lesions were epithelial lifting, hyperplasia and hypertrophy of the respiratory epithelium, lamellar fusion, and aneurysms in the gills; enlargement of the glomerulus, reduction of Bowman's space, occlusion of the tubular lumen, cloudy swelling and hyaline droplet degeneration in the kidneys; hepatocytes with hypertrophy, cytoplasmic and nuclear degeneration, melanomacrophage aggregates, bile stagnation and one case of focal necrosis in the liver. The lesions were comparatively most severe in the liver. Histopathology showed to be a very suitable biomarker for use in conjugation with the in situ test, because the seasonal variation did not interfere in the results and it was possible to differentiate the sites in the urban stream from the reference site.

- Enzymatic and histopathologic biomarkers as indicators of aquatic pollution in fishes (2010, background): “Alterations like fusion of some secondary lamellae are examples of defense mechanisms, since; in general, these result in the increase of the distance between the external environment and the blood and thus serve as a barrier to the entrance of contaminants [63,64].”
- Histopathological indicators: a useful fish health monitoring tool in common carp (Cyprinus carpio Linnaeus, 1758) culture (2013, unknown): “They are usually applied in research of polluted aquatic ecosystems, since they are good indicators of altered or polluted environments [5-9].”
