“…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 coccidians of the family Calyptosporidae are parasites of the tissue and organs of fish and aquatic invertebrates, in particular in the tropical region. In contrast with other apicomplexans of the suborder Eimeriorina, the diversity and ecology of the species of the genus Calyptospora have been poorly investigated, resulting in a lacuna that restricts the understanding of the distribution and prevalence of this group of eukaryote microparasites in the Amazon region. In the present study, the integrated comparative analysis of morphological characteristics, histological and structural traits, and the sequences of a fragment of the 18S rRNA gene, provides support for the identification of a new species of Calyptospora, found parasitizing the hepatic tissue of the piscivorous blue peacock bass, Cichla piquiti, captured in the reservoir of the Estreito hydroelectric dam on the middle Tocantins River in northern Brazil. This new species was named Calyptospora paranaidji n. sp.

Hepatic infection involving a parasite of the family Calyptosporidae was recorded in characiform fish from the Tocantins river in the Brazilian Amazon region. In the present study, an integrated comparative analysis of morphological characteristics, histological and structural traits, and the sequence of a partial fragment of the SSUrRNA gene provides support for the identification of a new calyptosporid species, found parasitising the hepatic tissue of the fish Triportheus angulatus, collected from the Tocantins River. This new species was named Calyptospora gonzaguensis n. sp. and had ovoid oocysts with a diameter of 19.6 AE 1.4 lm and four peripheral sporocysts, 9.2 AE 0.6 lm long and 3.9 AE 0.2 lm wide, enveloped individually in fine adhesive membrane, composed of an ellipsoid body and posterior extension, with a mean length of 2.2 AE 0.4 lm.

“…In more intense infections, the liver changes to a visibly lighter color (Videira et al, 2013;Velasco et al, 2012), resulting from the degeneration of liver tissue. As the oocysts proliferate, they cause inflammation and formation of granulomas coated with fibrous tissue (Ramos et al, 2018;Fournie & Overstreet, 1993;Solangi & Overstreet, 1980).…”

Calyptospora species are coccids that commonly cause liver infections in fish all around the world. This paper describes the morphology and histopathological characteristics of liver infection caused by Calyptospora sp. in black piranha Serrasalmus rhombeus, from the Capim River, in the municipality of Ipixuna do Pará, state of Pará (Brazil). Specimens were collected, analyzed and necropsied and tissue fragments containing parasites were prepared for histology and scanning electron microscopy. Parasitism was detected in 33.0% of the analyzed specimens, which had spherical oocysts in the liver, with four pyriform sporocysts presenting sporozoites internally. A histological examination revealed oocysts positioned close to blood vessels, causing necrosis and degeneration of hepatic parenchyma, while the presence of mononuclear cell infiltrate and melanomacrophages indicated the onset of an inflammatory process. This is the first record of the genus Calyptospora in fish from the Capim River.
