Calyptospora sp. in Brachyplatystoma vaillantii trapped at the Vigia, State of Pará, Brazil

Abstract

The article describes the first occurrence of hepatic coccidiosis in catfish of the species Brachyplatystoma vaillantii, captured in the coastal region of the Vigia city , state of Pará, Brazil, caused by species of the genus Calyptospora, family Calyptosporidae. Thirty specimens of piramutabas were examined where 60% were infected with liver location, featuring numerous mature and immature oocysts, grouped or isolated, with four sporocysts in pyriform shape. They were described on their morphology and dimensions of the oocysts and sporocysts, obtained from light microscopy and differential interference contrast.

“…The high prevalence of infection (47%) of Cichla piquiti by the hepatic coccidian Calyptospora paranaidji is consistent with the pattern of Calyptospora parasites observed in other fish species (Azevedo et al 1993;Fournie and Overstreet 1993;Silva et al 2012;Videira et al 2013). B ek esi and Moln ar (1991) recorded a 100% prevalence of liver infection by Calyptospora parasites in the butterfly peacock bass, Cichla ocellaris, introduced into natural and artificial environments (reservoirs) in the Brazilian Northeast.…”

“…The parasite prevalence rate found in this study is lower than other infections by Calyptospora, which were reported in Cichla temensis Heckel, 1840 (56.0%) (Santiago et al, 2012), Brachyplatystoma vaillantii Valenciennes, 1940 (60.0%) (Silva et al, 2012), Crenicichla lepidota Heckel, 1840 (63.0%) (Azevedo et al, 1993), Cichla ocellaris Bloch & Schneider, 1801 (100%) (Békési & Molnár, 1991) and 100% in carnivorous species collected by Negrão et al (2019).…”
