An injured juvenile sharp-shinned hawk, Accipiter striatus Vieillot, 1807 (Aves: Accipitriformes), housed and treated at the College of Veterinary Medicine Teaching Hospital at Kansas State University, Manhattan, Kansas, USA, was found to be passing oocysts of an undescribed species of Caryospora in its feces. Sporulated oocysts of Caryospora petersoni n. sp. were subspherical, with a bilayered wall, and they measured 43.1 × 39.8 μm; micropyle, oocyst residuum, and polar granule were absent. Sporocysts were subspherical to spherical, 23.4 × 23.3 μm; Stieda, substieda, and parastieda bodies were absent, but a spherical sporocyst residuum was present as a compact mass, ∼15.1 μm wide, composed of many homogeneous globules. The new species represents the first caryosporan documented from this species of hawk. © 2013 American Society of Parasitologists. Source

Isospora jaracimrmani Modr and Koudela is reported for the second time from the Yemen chameleon, Chamaeleo calyptratus. During November 1992, a captive C. calyptratus housed at the Dallas Zoo, Dallas County, Texas, U.S.A., was found to be passing oocysts of I. jaracimrmani. The original description of I. jaracimrmani was based on 18/43 (42%) captive specimens of C. calyptratus from the Czech Republic. This is the first time I. jaracimrmani has been reported from the United States. Comparative measurements and a photomicrograph of our isolate are included. © The Helminthological Society of Washington. Source

A captive specimen of Meller's chameleon, Trioceros melleri (Gray), originally from Tanzania and housed at the Oklahoma City Zoological Park Herpetarium, Oklahoma County, Oklahoma, was found to be passing an undescribed species of Choleoeimeria in its feces. Oocysts of Choleoeimeria steveuptoni n. sp. were cylindroidal, 38.5 × 17.8 (3642 × 1719) m with a bilayered wall and a shape index (length/width) of 2.2. A micropyle and oocyst residuum were absent, but a fragmented polar granule was often present. Ovoidal sporocysts were composed of 2 valves joined by a suture and measured 11.3 × 9.1 (1112 × 910) m; shape index of 1.3. Stieda, sub-Stieda, and para-Stieda bodies were absent. The sporocyst residuum consists of multiple globules dispersed along the perimeter of the sporocyst and between sporozoites. Sporozoites were elongate, 13.1 × 2.9 (1215 × 2.63.2) m with an elongate posterior refractile body. The new species represents the second coccidian documented from this lizard. © American Society of Parasitologists 2012. Source

Two hundred twenty-two individual reptiles (11 families, 45 species) from 17 districts of Namibia were examined for endoparasites. Thirty-three (31 lizards, 2 snakes) individuals (15%) were found to harbor at least 1 species of helminth; 4 lizards harbored a multiple infection of 2 helminths, 1 lizard was infected with 3 species, and 1 lizard harbored a multiple infection of 5 species. One species of linstowiid cestode, 12 species of nematodes representing 6 families, and 1 species of cephalobaenid pentastomid were found in the herpetofauna surveyed. Twenty-seven new host and 8 new geographic records are documented for helminths of Namibian reptiles. © 2011 The Helminthological Society of Washington. Source

Between September and October 1991 and again during September 1992, skinks (Emoia spp.) were collected from various localities on Fiji and Papua New Guinea (PNG) and examined for coccidians. One of 4 (25%) De Vis' emo skinks (Emoia pallidiceps) from PNG harbored an undescribed species of Isospora in its feces. Oocysts of Isospora grinbikpelapalai n. sp. were ellipsoidal to subspheroidal, 18.1 × 14.9 (17-20 × 14-16) μm, with a bilayered wall and a length/width index (L/W) of 1.2. Both micropyle and oocyst residuum were absent, but a prominent polar granule was present. Sporocysts were ovoidal, 10.7 × 7.6 (10-11 × 7-8) μm, with a L/W index of 1.4. Stieda and sub-Stieda bodies were present, but para-Stieda bodies were absent. The sporocyst residuum consisted of large scattered globules dispersed between sporozoites. Sporozoites were elongate with spheroidal anterior and posterior refractile bodies. Isospora grinbikpelapalai was also found in 1 of 2 (50%) Pope's emo skinks (Emoia popei) from PNG. One of 13 (8%) white-bellied copper-striped skinks (Emoia cyanura), from Fiji, was passing another undescribed species of Isospora in its feces. Oocysts of Isospora casei n. sp. were elongate, 31.8 × 21.3 (28-35 × 18-24) μm, with a bilayered wall and a L/W index of 1.5. Micropyle, oocyst residuum, and polar granule were all absent. Sporocysts were ovoidal, 15.3 × 10.6 (14-16 × 10-12) μm, with a L/W index of 1.4. Stieda and sub-Stieda bodies were present, but para-Stieda bodies were absent. The sporocyst residuum consisted of scattered globules among sporozoites or as a cluster surrounding sporozoites. Sporozoites were elongate with spheroidal anterior and posterior refractile bodies. Isospora casei was also found in 1 of 2 (50%) Fiji slender treeskinks (Emoia concolor) from Fiji. This represents the first report of coccidia from Emoia spp. and, to our knowledge, the initial documentation of reptilian coccidia from herpetofauna from Papua New Guinea. © American Society of Parasitologists 2013.
