SANT'ANA, Fabiano J.F. de et al. Outbreaks of Piscinoodinium pillulare and Henneguya spp. infection in intensively raised Piaractus mesopotamicus in Southwestern Goiás, Brazil. Pesq. Vet. Bras. [online]. 2012, vol.32, n.2, pp.121-125. ISSN 0100-736X.

Three outbreaks of infection by Piscinoodinium pillulare and Henneguya spp. in Piarac tus mesopotamicus intensively raised in Southwestern Goiás, Brazil, are described. Two outbreaks occurred in the winter and another one in summer. Morbidity (58.57%-90%) and mortality (100%) rates were determined. Stress episodes occurred previously in all cases. Clinical signs included behavior changes and erratic movements with loss of equilibrium. Main gross findings were swelling of the gills with white mucus exudate. Microscopically, gills had mild to moderate multifocal necrotizing and lympho-plasmocytic inflammation with hypertrophy and fusion of secondary lamellae. In addition, numerous intralesional trophonts of P. pillulare and cysts of Henneguya spp. were noted. According to our knowledge, this seems to be the first description of Piscinoodinium pillulare e Henneguya spp. infection in fishes reared in Southwestern Goiás, Brazil.
