“…Therefore, the present study corroborates with those described above, since the Leptodactylidae includes species with a semi-aquatic lifestyle. Moreover, although there are only a few reports on Hepatozoon prevalence among Brazilian frogs, individuals of Leptodactylidae are commonly reported to be parasitised by species of Hepatozoon ( Cunha and Muniz, 1927 ; Da Costa, et al 1973 ; Leal et al, 2015 ; Ferreira et al, 2020 ).…”

The Amphibia are considered the most threatened vertebrate class globally, yet in Brazil they are also one of the more diverse and species rich groups. Although, in recent years there has been strong focus on amphibian related research, their parasites have not received the same attention. In Brazil, only a single species of Hepatozoon , namely H. leptodactyli (Lesage, 1908) Pessoa, 1970, has been described from anuran hosts. The present study aimed to describe three new species of Hepatozoon parasitising Leptodactylus labyrinthicus and Leptodactylus latrans from Mato Grosso State, Brazil. From 66 anurans screened for haemogregarines, four belonging to the Leptodactylidae were found positive for species of Hepatozoon . Based on the morphological analysis of peripheral blood gamonts and spleen and liver tissue meronts, three different morphotypes of Hepatozoon spp. were identified. Morphotype 1 (M1) and morphotype 2 (M2) in L. labyrinthicus and morphotype 3 (M3) in L. latrans. Molecular data based on partial 18S rDNA sequences revealed an interspecific divergence, between the species ranging from 0.43% to 1.16%. Phylogenetic analysis recovered isolates from the present study monophyletic with other isolates from Brazilian reptile and anuran hosts, sister to a clade comprising species isolated from African, North American and European reptile and anuran host species. Thus, using morphological and molecular analysis three new species infecting Brazilian Leptodactylidae anurans were identified and described. This study increases the knowledge of Brazilian anurans blood parasites and demonstrates the importance of using integrative approaches for diagnosis of hemoparasites.

“… Cunha and Muniz (1927) reported in detail the schizogony in the liver, lung, and intestine of a haemogregarine infecting Leptodactylus latrans from Brazil. Another study, by Da Costa et al (1973) used morphological and morphometric data, to formally described H. leptodactyli, infecting individuals of Leptodactylidae.…”

“…Ademais, nas hemácias de Bufo paracnemis nunca foram vistas formas com as extremidades dobradas como descritas em outros hospedeiros por outros autores (v. g. Cunha & Muniz 1928) Os eritrócitos não manifestavam alterações morfológi -cas, salvo naqueles casos contendo duas cápsulas ou quando a única forma capsulada era de dimensões hipertrofiadas.…”

Foram examinadas cem preparações de sangue de Bufo paracnemis, coletados em João Pessoa, Estado da Paraíba, Brasil. Oito exemplares destes anuros mostraram-se portadores de formas parasitas de uma espécie de Haemogregarina "sensu lato". As hemácias habitualmente continham parasitos alongados ou encapsulados. Duplo parasitismo foi diversas vezes observado. Deformação do eritrócito era rara e ocorria guando havia duas cápsulas ou apenas uma hipertrofiada. Duas fêmeas partenogenéticas do carrapato Amblyomma rotundatum Koch, 1844, encontradas sobre a pele de um dos sapos, seriam vetores deste hemoparasito.
