“…In contrast, A. bubonis and A. henryae have scattered sporocyst residuum. In fact, as emphasized by Upton et al (1986), A. henryae was described from several hosts of different forms and, therefore, it is possible that more than one species may be involved; however, in any case, none of these descriptions of A. henryae contain sub-spherical sporocysts with an irregular-subspherical body consisting of numerous granules that appear to be membrane-bounded (UPTON et al, 1986;1990).…”

“…However, Upton et al (1986) contested this transmission between different orders of Aves, taking the view that these subsequent reports should be of other coccidian species. Bubo bubo is sympatric with A. noctua in the Russian region (KONTORSHIKOV et al, 1996); therefore, it would be possible for these owls to share the same coccidian species, but as mentioned above, the morphology identified in the oocysts of the current work is incompatible with all descriptions of A. henryae.…”

“…In fact, previous studies had already highlighted the evident morphological and biological differences of Caryospora spp. found in raptors and reptiles, such as the presence of a Stieda body and developmental details in the intermediate host, especially regarding caryocysts, along with the evident host specificity (CAWTHORN & STOCKDALE, 1981;WACHA & CHRISTIANSEN, 1982;UPTON et al, 1986;BERTO et al, 2014).…”

The little owl Athene noctua (Scopoli, 1769) is a small raptor that is widely distributed from northern to southern Portugal and several other countries in Europe, Asia and North Africa, and which has been introduced into New Zealand. In the current study, 18 fecal samples were collected from little owls kept at the Lisbon Center for Wild Animal Recovery, which is located in Monsanto Forest Park, Lisbon, Portugal. Twelve (67%) of them were found to be passing an undescribed species of Avispora in their feces. The oocysts of Avispora mochogalegoi n. sp. were ellipsoidal with a bilayered wall and measured 38.9 × 32.9 µm, with a shape index of 1.18. No micropyle, oocyst residuum or polar granule was present. The sporocysts were subspherical, measuring 21.1 × 20.1 µm. Stieda, sub-Stieda and para-Stieda bodies were absent. The sporocyst residuum was composed of a compact subspherical mass of granules. This is the fourth species of Avispora reported in Strigiformes.

“…However, since falconids are close to accipitrids, and because earlier studies on Caryospora spp. in raptors compared coccidians through descriptions from these two families (UPTON et al, 1986(UPTON et al, , 1990, C. peneireiroi was also compared in the current work with Caryospora spp. described from Accipitridae.…”

The common kestrel Falco tinnunculus Linnaeus, 1758, is a widespread raptor, native in Europe, Asia and Africa, and vagrant in the Americas. In the current work, 27 fecal samples were collected from common kestrels kept in the Lisbon Center for Wild Animal Recovery, located at Monsanto Forest Park, Lisbon, Portugal. Five (19%) of them were found to be passing an undescribed species of Caryospora in their feces. The oocysts of Caryospora peneireiroi n. sp. were ellipsoidal with a bilayered wall and measured 47.1 × 37.6 µm with a shape index of 1.25. No micropyle, oocyst residuum or polar granule was present. The sporocysts were subspherical, measuring 25.1 × 24.3 µm. Stieda, sub-Stieda and para-Stieda bodies were absent. The sporocyst residuum was composed of many homogenous globules scattered throughout the periphery of the sporocyst. This is the fourth caryosporan species reported from F. tinnunculus.

“…Caryosporan coccidia represent relatively common parasites of snakes and raptorial birds from which more than 70 species have been described to date (Upton et al 1986, 1990, Modrý 1999. However, the presence of parasites of this genus in saurian hosts is exceptional.…”

Abstract. Parasitological examination of two ornate Nile monitors Varanus ornatus (Daudin, 1803) imported from Benin revealed the presence of a new species of Caryospora. Oocysts of Caryospora varaniornati sp. n. are spherical to slightly subspherical, 12.0 (11-12.5) × 11.5 (11-12) µm, without a micropyle and oocyst residuum, and occasionally possessing one small polar granule. Sporocysts are broadly ellipsoidal, 8.8 (8.5-9.5) × 6.7 (6.5-7) µm; a lentil-like Stieda body is present, ca. 0.5 × 1 µm; substieda body not visible. Experimental infection of a closely related host, Varanus niloticus (L.), did not lead to the oocyst excretion despite the fact that one of the experimentally inoculated monitors was immunosuppressed by dexamethasone. Histological examination did not reveal stages of coccidian development. Therefore, it is possible that C. varaniornati is strictly host specific.Coccidia of the genus Caryospora Léger, 1904 (Apicomplexa: Eimeriidae) are widely distributed among snakes and raptorial birds and only a few species have been described from other hosts. Only two species have been described to date from saurian hosts in contrast to the diversity of these coccidia in snakes, from which 46 caryosporan species are listed (Modrý 1999). In this paper we describe a new Caryospora species from the African monitor lizard Varanus ornatus (Daudin, 1803) (Sauria: Varanidae), a member of the poorly understood Varanus niloticus (L.) species complex. MATERIALS AND METHODSAn adult specimen of the ornate Nile monitor, Varanus (Polydaedalus) ornatus from ZOO Brno, at that time hospitalised at the University of Veterinary and Pharmaceutical Sciences, Brno due to a fracture of the hind limb, was parasitologically examined. Based on data provided by the owner (ZOO Brno), the animal originated from a group of wild-caught Nile monitors recently imported by a pet-trader from Benin in West Africa. The hospitalised animal was kept in quarantine in a glass terrarium and fed on day-old chicks and adult laboratory mice. Faecal samples were collected repeatedly from the floor of the cage and submitted for parasitological examination. Later, faecal samples of a cagemate ornate Nile monitor of the same origin were also provided for parasitological examination by ZOO staff. The faecal samples were examined microscopically after concentration by flotation with modified Sheather's sugar solution (s.g. 1.30). Fresh samples containing unsporulated coccidian oocysts were allowed to sporulate in Petri dishes at room temperature (20-23°C) and examined daily to determine the stage of sporulation. Sporulated oocysts were measured and photographed using Nomarski interference contrast (NIC) optics. Measurements were made using a calibrated ocular micrometer and are reported in micrometres, as means, followed by the ranges in parentheses. Sporulated oocysts were purified by flotation in Sheather's sugar solution and stored in 2.5% aqueous solution (w/v) of potassium dichromate at 4°C for one month before further use.Two juvenile, ca. 6 months...
