“…Two different species from the family Falconidae were sampled: the lesser kestrel Falco naumanni Fleischer, 1818 and the common kestrel Falco tinnunculus Linnaeus, 1758. Only the common kestrels were positive for a coccidian species, which was identified as Avispora peneireiroi (Cardozo, Berto, Caetano, Maniero, Fonseca, Lopes, 2016). Its oocysts ( Figure 1A) were described by Cardozo et al (2016) as ellipsoidal with a bilayered wall.…”

“…Sporozoites without striations discernible, but with one spherical refractile body and a nucleus. This species was originally described in the genus Caryospora Leger, 1904(CARDOZO et al, 2016. However, after the work of Schuster et al (2016), all species of Caryospora that had been recorded in raptors were taxonomically transferred to the genus Avispora, based on the morphological, biological and molecular differences in Caryospora spp.…”

“…Portugal is a potentially favorable country for a study model in this regard, since it has birds that have previously been described as hosts of several coccidian species, both in the wild and in captivity/breeding (BERTO et al, 2014b;CARDOZO et al, 2015CARDOZO et al, , 2016CARDOZO et al, , 2017. In this context, the aim of the current study was to identify coccidian species that were recovered from wild birds at two rehabilitation centers for wild animals located in two municipalities of Portugal.…”

Portugal has some rehabilitation centers for wild animals, which are responsible for the rehabilitation and reintroduction of birds, among other animals, into the wild. Coccidian parasites of these wild birds in rehabilitation centers are especially important because these centers can introduce coccidian species into new environments through the reintroduction of their respective hosts. In this context, the current study aimed to identify intestinal coccidia from wild birds at two rehabilitation centers for wild animals located in two municipalities of Portugal. Eighty-nine wild birds of 9 orders and 11 families were sampled, of which 22 (25%) were positive for Coccidia. Avispora spp. were found in raptors. Sporocysts of Sarcocystinae subfamily were recovered from owls. An Isospora sp. was found in Turdus merula Linnaeus, 1758, and an Eimeria sp. was found in Fulica atra Linnaeus, 1758. Among the coccidian species, Avispora bubonis (Cawthorn, Stockdale, 1981) can be highlighted. The finding of this species indicates that transmission of coccidians from the New World to the Old World may be occurring, potentially through dispersion by Bubo scandiacus (Linnaeus, 1758) through Arctic regions or by means of anthropic activities, and/or through other unknown mechanisms.

The genus Eumonospora Allen, 1933 (Apicomplexa: Sarcocystidae), an avian coccidia, is characterized by monosporocystic and octasporozoic oocysts without Stieda and substieda bodies. Some members of Eumonospora , which infect several raptor species, exhibit high levels of pathogenicity, making eumonosporiosis the leading cause of death in captive-bred raptors. The host specificity of these species appears to be mesostenoxenous, as evidenced by unsuccessful transmission between different orders of avian hosts. However, several studies have detected Eumonospora spp. in taxonomically distant avian hosts, indicating that some of these species may be euryxenous. In the current study, diarrheic fecal examination of a captive-bred juvenile merlin (Falconiformes: Aves) in Tokyo, Japan, was conducted, and a large number of oocysts were morphologically and molecularly identified as E. henryae (Yakimoff and Matschulsky, 1932), a coccidia species reported only in Strigiformes. This is a new recorded host for this coccidia. Phylogenetic analyses via Bayesian inference and maximum likelihood methods using concatenated genomic datasets consisting of nuclear 18S rDNA, nuclear 28S rDNA and mitochondrial cytochrome C oxidase subunit 1 gene, revealed a well-supported monophyletic clade of Eumonospora spp. belonging to the family Sarcocystidae Poche 1913, which largely corresponded to the avian host phylogram. Therefore, based on distinguishable oocyst morphology, a new subfamily, Eumonosporinae, within the family Sarcocystidae, is proposed, and a reconsideration of the definition of Sarcocystidae is suggested. Further molecular characterization of this emerging pathogen, as well as clarification of its complete life cycle, including cyst-forming ability, is required for more appropriate generic assessment.
