Two New Species of Eimeria and Three New Species of Isospora (Apicomplexa, Eimeriidae) from Brazilian Mammals and Birds
Bull. Mus. nain. Hist. nat., Paris, 4' sér., 11, 1989, section A, n° 2 : 349-365. Two new species of Eimeria and three new species of Isospora (Apicomplexa, Eimeriidae) from Brazilian mammals and birds by R. LAINSON and J. J. SHAW Abstract. — Thirteen " four-eyed opossums ", Philander o. opossum, from Para State, north Brazil, were examined for coccidial oocysts in faecal samples. Five were infected with an eimerian, considered a new species, 2 with an isosporan which is possibly /. boughtoni Volk, and 2 with both thèse parasites. Oocysts of Eimeria philanderi n. sp., are spherical to subspherical and average 23.50 x 22.38 (21.25- 27.50 x 18.75-25.00) (xm : single polar body : no oocyst residuum. Oocyst wall 1.88 [ira, with mamillated surface and composed of two striated layers, the inner brown-yellow and the outer colourless : no micropyle. Sporocysts average 11.35 x 8.13 (10.00-12.00 x 7.50-8.75) (xm, oval to ellipsoidal, with prominent nipple-like Stieda body : residuum bulky, compact or scattered between two recurved sporozoites.

FOLIA PARASITOLOGICA 53: 91–97, 2006 New species of Choleoeimeria (Apicomplexa: Eimeriidae) from the veiled chameleon, Chamaeleo calyptratus (Sauria: Chamaeleonidae), with taxonomic revision of eimerian coccidia from chameleons Michal Sloboda1 and David Modrý1,2 1Department of Parasitology, University of Veterinary and Pharmaceutical Sciences Brno, Palackého 1–3, 612 42 Brno, Czech Republic; 2Institute of Parasitology, Academy of Sciences of the Czech Republic, Branišovská 31, 370 05 České Budějovice, Czech Republic Key words: Coccidia, Eimeriorina, Choleoeimeria, taxonomy Abstract. Coprological examination of 71 samples from a breeding colony of veiled chameleons, Chamaeleo calyptratus Duméril et Duméril, 1851, revealed a presence of two species of coccidia. In 100% of the samples examined, oocysts of Isospora jaracimrmani Modrý et Koudela, 1995 were detected. A new coccidian species, Choleoeimeria hirbayah sp. n., was discovered in 32.4% of samples from the colony. Its oocysts are tetrasporocystic, cylindrical, 28.3 (25–30) × 14.8 (13.5–17.5) µm, with smooth, bilayered, ~1 µm thick wall. Sporocysts are dizoic, ovoidal to ellipsoidal, 10.1 (9–11) × 6.9 (6–7.5) µm, sporocyst wall is composed of two plates joined by a meridional suture. Endogenous development is confined to the epithelium of the gall blad- der, with infected cells being typically displaced from the epithelium layer towards lumen. A taxonomic revision of tetrasporo- cystic coccidia in the Chamaeleonidae is provided.

It is globally distributed and an important cause of foodborne outbreaks of enteric disease in many developed countries, mostly associated with the consumption of contaminated fresh produce. Because oocysts are excreted unsporulated and need to sporulate in the environment, direct person-to-person transmission is unlikely. Infection by C. cayetanensis is remarkably seasonal worldwide, although it varies by geographical regions. Most susceptible populations are children, foreigners, and immunocompromised patients in endemic countries, while in industrialized countries, C. cayetanensis affects people of any age. The risk of infection in developed countries is associated with travel to endemic areas and the domestic consumption of contaminated food, mainly fresh produce imported from endemic regions. Water and soil contaminated with fecal matter may act as a vehicle of transmission for C. cayetanensis infection. The disease is self-limiting in most immunocompetent patients, but it may present as a severe, protracted or chronic diarrhea in some cases, and may colonize extra-intestinal organs in immunocompromised patients. -
