Abstract: 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 Tocant… Show more

“…This is a typical histopathological finding of Calyptospora and has been described in several studies (Békési & Molnár, 1991;Ramos et al, 2018;Velasco et al, 2012;Santiago et al, 2012). However, minor variations occur, with some species showing tropism only in blood vessels, as observed in C. gonzaguensis, or only in the liver parenchyma, such as C. paranaidji (Silva et al, 2020;Da Silva et al, 2019).…”

“…However, the morphometric comparisons showed greater proximity to Calyptospora sp. 4 found in Arapaima gigas (Bonar et al, 2006) and C. gonzaguensis described in Triportheus angulatus (Silva et al, 2020), which were particularly congruent with the diameter of the oocysts, of 19 µm and 19.6 µm, respectively (Table 1).…”

“…Apenas um trabalho foi publicado recentemente sobre protozoários no estado, onde Silva et al (2020a) Para identificação dos parasitas, foram utilizados protocolos de histologia (Casal et al, 2007) e análises moleculares como a PCR (Whipps et al, 2012;Dogga et al, 2015;Matos et al, 2018).…”
