“…Moreover, Schellackia has been described parasitizing frogs before (i.e. Paperna & Lainson 1995). The case of E. arnyi is surprising as its host is the prairie ringneck snake (Upton & Oppert 1991), and no Schellackia species is known to infect ophidians.…”

Molecular characterization of haemococcidia genus Schellackia (Apicomplexa) reveals the polyphyletic origin of the family Lankesterellidae

The current taxonomy on the haemococcidia establishes that the two genera of protozoan parasites that integrate the family Lankesterellidae are Lankesterella and Schellackia. However, the phylogeny of these genera, as well as the other coccidia, remains unresolved. In this sense, the use of type and described species is essential for the resolution of systematic conflicts. In this study, we molecularly characterize the type species of the genus Schellackia, that is, S. bolivari from Europe and also a described species of the same genus from Asia. At the same time, we contribute with the molecular characterization of another species of the genus Lankesterella. All this put together supports the polyphyly of the family Lankesterellidae. Therefore, we propose the resurrection of the zoological family, Schellackiidae Grassé , to include species within the genus Schellackia.

“…Eight species have been reported from the Old World, two from North America and one in Brazil (Table 1). Additionally, two species from South America are reported infecting frogs: Schellackia balli Le Bail and Landau, 1974 from the Cane toad ( Rhinella marina ) and an unnamed Schellackia from a Brazilian tree-frog ( Phrynohyas venulosa ) (Le Bail and Landau, 1974; Paperna and Lainson, 1995). Furthermore, two Lainsonia Landau, 1973 species ( Lainsonia iguana Landau, 1973 and Lainsonia legeri Landau et al ., 1974), described also from Brazil (Landau, 1973; Landau et al ., 1974) are considered by some authors to be Schellackia (Levine, 1980; Upton, 2000).…”

Apicomplexan haemoparasites of the genera Schellackia Reichenow, 1919, and Karyolysus Labbé, 1894, seem to be common in lizards and widespread across the world. For decades, their identification has been based on morphological descriptions and life cycle patterns, with molecular characterizations, applied only recently. We used molecular characterization to confirm the identification of haemoparasites detected by microscopy in blood smears of Lacerta schreiberi Bedriaga, 1878, a lizard of the Iberian Peninsula. Since blood samples other than blood smears were not available from the studied lizards, 264 engorged ticks Ixodes ricinus (Linneaus, 1758) collected from them were used as an alternative non-invasive source of haemoparasite DNA for molecular genetic analyses. Of the 48 blood smears microscopically examined, 31 were positive for blood parasites (64.6% prevalence). We identified trophozoites and gamonts similar to Karyolysus lacazei (Labbé, 1894) (24/48; 50%) and Schellackia-like sporozoites (20/48; 41.7%). Mixed infections with both species occurred in 13 blood smears (27.1%). Sequence data were obtained for both parasites from engorged ticks. Phylogenetic analyses placed our unique haemogregarine sequence within the Karyolysus clade, nevertheless, within substantial polytomy. Thus, according to its morphology and effect on the host cell, we refer to this haemogregarine as Karyolysus cf. lacazei. Besides the Schellackia sequences being identical to a previously identified haplotype, we also obtained sequences of three new closely related haplotypes.

Schellackia (Apicomplexa: Eimeriidae) of the brazilian tree-frog, Phrynohyas venulosa (Amphibia: Anura) from Amazonian Brazil

Abstract: Endogenous stages of a Schellackia species are described in histological sections of the intestine of the tree-frog, Phrynohyas venulosa, from North Brazil. Most oocysts sporulate within the epithelial cells of the gut, but a few were detected in the lamina propria
