| Resumo: |
The purpose of the study was to evaluate the susceptibility of 4 important cultivated fishes to sporozoan parasites. Fishes were collected bimonthly from a pond for a period of 1 year. Myxobolus colossomatis and Henneguya piaractus were found in the internal organs and gills, respectively. The combined incidence of parasitism by both myxozoa was 97.3% in pacu (Piaractus mesopotamicus), 33.3% in hybrid tambacu (Piaractus mesopotamicus x Colossoma macropomum), 5.6% in tambaqui (Colossoma macropomum) and 0% in carp (Cyprinus carpio). Pacu was the most susceptible fish and was parasitized 79.2% in the gills, 66.7% in the kidney and 50% in the spleen. Histopathological evaluation of the gills showed hemorrhages, inflammatory reaction with mononuclear cells and fibroblasts and hyperplasia of basal and goblet cells.
