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.

Abstract: During September 2004, 4 adult northern myotis, Myotis septentrionalis, were collected from LeFlore County, Oklahoma (n 2), and Logan (n 1) and Yell (n 1) counties, Arkansas, and their feces examined for coccidian parasites. Three of 4 bats (75) were passing oocysts of Eimeria spp. Oocysts of Eimeria tumlisoni n. sp. were subspherical, 17.6 × 16.8 (1619 × 1418) m with a shape index of 1.0 (1.01.1). A micropyle and oocyst residuum were absent, although 12 bilobed polar granules were often present. Sporocysts were ovoidal, 10.5 × 5.9 (912 × 57) m with a shape index of 1.8 (1.62.0). A Stieda body was present, but substieda and parastieda bodies were absent. A sporocyst residuum was present consisting of compact to dispersed granules between the sporozoites. The sporozoites were elongate, with subspherical anterior refractile body and spherical posterior refractile body; a nucleus was not discernable. This is the second coccidian reported from this host and the first instance of a bat coccidian reported from Oklahoma. We also document a new geographic record for Eimeria catronensis in Oklahoma and provide an emended description. © American Society of Parasitologists 2012.

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.

Between April 2012 and September 2013, feces from 18 green anoles, Anolis carolinensis from Arkansas (n = 14), Louisiana (n = 1), and Oklahoma (n = 3) were examined for coccidia. Two species of coccidians were found, including a new caryosporan and a new eimerian. Oocysts of Caryospora natchitochesensis n. sp. from a single A. carolinensis from Louisiana were subspheroidal to ovoidal with a smooth, yellow-to-brown-pigmented, bilayered wall of equal thickness (∼0.3-0.7) and measured (L × W) 13.1 × 12.3 μm, with a length/width (L/W) ratio of 1.1. A micropyle and oocyst residuum were absent, but a polar granule was present. Sporocysts were ovoidal and measured 10.1 × 7.4 μm, L/W was 1.4. A Stieda body (∼1.0 μm) was present, but substieda and parastieda bodies were absent. The sporocyst residuum was composed of dispersed granules or globules among sporozoites. Oocysts of Eimeria robisoni n. sp. from 1 of 12 (8%) green anoles from Arkansas were ellipsoidal with a smooth, unilayered wall (∼0.4-0.5) and measured (L × W) 14.5 × 10.5 μm, with L/W ratio of 1.4. A micropyle and oocyst residuum were absent, but 1-4 (usually 2) polar granules were present. Sporocysts were subspheroidal to ovoidal and measured 5.8 × 4.9 μm, L/W was 1.2. Stieda, substieda, and parastieda bodies were absent. The sporocyst residuum was composed of dispersed granules between sporozoites. None of the anoles from Oklahoma was found to be passing oocysts. This is the second time an eimerian and a caryosporan have been reported from green anoles. A summary of the coccidians of lizards of the family Dactyloidae is provided, with special emphasis on the Anolis of the United States. © American Society of Parasitologists 2014.

Between March 1989 and February 1994, 4 bald eagles (Haliaeetus leucocephalus) from various localities in Kansas were examined for coccidia. One (25%) of the bald eagles was found to be passing an undescribed species of Caryospora in its feces. Oocysts of Caryospora hanebrinki n. sp. are ellipsoidal to ovoidal with a bilayered wall and measure 48.1 × 42.1 μm with a shape index of 1.2. A micropyle, oocyst residuum, and polar granule were absent. Sporocysts are spheroidal, 24.8 μm wide. Stieda, substieda, and parastieda bodies were absent; a spheroidal sporocyst residuum is present; it measures 17.5 μm and is composed of many intact homogenous globules with a few dispersed in a loose spiral around the sporocysts. This is the first caryosporan documented from the bald eagle and is the largest known Caryospora from raptors. © American Society of Parasitologists 2013.

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.

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.


ABSTRACT: Sixteen of 22 (73%) Roemer's snails, Mesodon roemeri, collected in June 1989 from Johnson County, Texas were found to be passing oocysts of Pfeifferinella gugleri (Wacha, 1980) in their feces. Oocysts had no sporocysts but each contained 8 free sporozoites and a distinct oocyst residuum and micropyle. This coccidian was originally described from the white-lipped land snail, Neohelix (=Triodopsis) albolabris from Iowa, and also has been reported from the land snail Oxyloma retusa from Minnesota. Six additional species of snails (n = 31) were surveyed and were not found to be passing coccidian oocysts.
