Resumo
Twenty Nile tilapia (Oreochromis niloticus) parasitised by Epistylis sp. were collected for haematological and histopathological analysis. Fish with >400 zooids showed increase in lymphocyte and decrease in neutrophil population (p<0.05), compared to the less parasitised group (<400). Histopathologic analysis showed that Epistylis sp. induces a chronic inflammatory response in the host, possibly provoked by constant contact with the fish skin.
