“…Remark: Isospora automoli oöcysts present similar dimensions to those of I. scleruri; however, they can be distinguished based on the morphology of the substieda body (McQuistion et al, 1999) (Table 2). Doležalová et al (2004) recovered oöcysts of this species from the faeces of barethroated bellbirds in Spain. The birds had been recently imported from Brazil by The Barcelona City Zoo and were examined because they were in quarantine.…”

Coccidia of New World passerine birds (Aves: Passeriformes): a review of Eimeria Schneider, 1875 and Isospora Schneider, 1881 (Apicomplexa: Eimeriidae)

In the New World, the avian order Passeriformes comprises 47 families and 2,453 species, yet to date only 21 (45%) of the families and 58 (2%) of the species have been examined for coccidia, and from these only two species of Eimeria Schneider, 1875 and 81 species of Isospora Schneider, 1881 have been described. This review contributes to our understanding of the morphology and systematics of coccidian parasites of passeriforms, providing a scientific basis for the identification of sporulated oöcysts recovered from the faeces of passerine birds from North, Central and South America. To this end, the coccidia were organised and grouped according to the family of the host, following the widely recognised concept of family-specificity and the updated systematics of the class Aves. Details of 83 eimeriid species are presented along with an illustration and tabulated data.

“…The parvorder Tyrannida brings together the family Pipridae and the superfamilies Cotingoidea (Oxyruncidae, Onychorhynchidae, Tityridae and Cotingidae) and Tyrannoidea (Pipritidae, Platyrinchidae, Tachurisidae, Rhynchocyclidae and Tyrannidae) [23]. Only four of these ten families of Tyrannida has coccidian species recorded: ( 1 4) I. lopesi in Platyrinchidae [24][25][26][27][28]. As shown in Table 1, I. oliveirai is easily differentiated from these coccidian species by several characteristic features, such as: roughness of the outer layer of the oocyst wall, number and arrangement of polar granules, shape of the Stieda and sub-Stieda bodies, in addition to that the oocysts of I. oliveirai are larger than all species recorded from the parvorder Tyrannida.…”

Isospora oliveirai n. sp. (Chromista: Miozoa: Eimeriidae) from the Greenish Schiffornis Schiffornis virescens (Lafresnaye, 1838) (Passeriformes: Tyranni: Tityridae) in South America

Background Coccidia are obligatory intracellular parasites with at least one intestinal phase in their life cycles, being Isospora Schneider, 1881 the main coccidian genus related to the order Passeriformes. However, there is no record of isosporans from the passerine family Tityridae, which is the family of the greenish schiffornis Schiffornis virescens (Lafresnaye, 1838). Purpose This study aimed to examine the faeces from a greenish schiffornis S. virescens captured in the Itatiaia National Park, State of Rio de Janeiro, Southeastern Brazil, to determine what coccidian parasites were present. Methods Only one specimen of Schiffornis virescens was captured with mist nets. Coccidian oocysts were recovered from the fecal samples by flotation in Sheather's saturated solution. Morphological observations, line drawings, photomicrographs and measurements were made in optical microscopy and digitally edited. The molecular analysis included the study of the sequence of the mitochondrial cytochrome c oxidase subunit 1 (COI) gene, with phylogenetic reconstructions based on the Neighbor-Joining and Maximum Likelihood analysis. Results An Isospora sp. considered as new to science is described and identified from Schiffornis virescens (Lafresnaye, 1838). Isospora oliveirai n. sp. has oocysts that are subspheroidal, 26.0 × 24.8 μm, with rough, bilayered wall, c.2.5 μm thick. Micropyle and oocyst residuum absent, but one to six polar granules are present. Sporocysts lemon-shaped, 18.1 × 10.9 μm. The Stieda body is knob-like to half-moon-shaped and sub-Stieda is rounded. Sporocyst residuum is present, composed of scattered spherules of different sizes. Sporozoites are vermiform, with refractile bodies and nucleus. Molecular analysis at the COI gene exhibited similarity of 97% with Isospora serinuse Yang, Brice, Elliot et Ryan, 2015 from island canaries Serinus canaria (Linnaeus, 1758), and Isospora spp. from great tits Parus major (Linnaeus, 1758) and European robins Erithacus rubecula (Linnaeus, 1758). Conclusion Based on the morphological and molecular features, I. oliveirai is considered as new to science and the first coccidian species recorded from Tityridae.

“…From these families, only a single isosporoid coccidium has been described, i.e. I. araponga Doležalová, Torres Fernán-dez & Modrý, 2004, as parasitising a bare-throated bellbird Procnias nudicollis (Vieillot) (see Doležalová et al, 2004). I. araponga can easily be differentiated from I. feroxis because it presents ellipsoidal oöcysts, asymmetrical sporocysts and an indistinguishable SSB.…”

In the current study, two new coccidian species (Protozoa: Apicomplexa: Eimeriidae) obtained from short-crested flycatcher Myiarchus ferox (Gmelin) are reported from Brazil. Isospora feroxis n. sp. has oöcysts which are spheroidal to sub-spheroidal, 18.7 x 18.0 microm, with a smooth and bi-layered wall, c. 1.2 microm. The micropyle and oöcyst residuum are absent, but two polar granules are present. Its sporocysts are broadly ellipsoidal and 11.7 x 8.5 microm. Stieda and substieda bodies are present. A sporocyst residuum is present and the sporozoites have a refractile body and nucleus. Oöcysts of Eimeria sicki n. sp. are spheroidal to sub-spheroidal, 30.3 x 28.5 microm, with a smooth and bi-layered wall, c. 1.3 microm. The micropyle, oöcyst residuum and polar granule are absent. Its sporocysts are ellipsoidal, 18.4 x 10.0 microm. Stieda and substieda bodies are present. A sporocyst residuum is present and sporozoites have a refractile body and nucleus.

Abstract: Faecal samples from a couple of bare-throated bellbirds Procnias nudicollis imported from Brazil to BarcelonaZoo contained oocysts of Isospora araponga n. sp. Sporulated oocysts were subspherical to broadly ellipsoidal, 19.5 (17-22) × 15.5 (14-16.5)
