Coccidia of Guinea fowls: Validity of recorded Eimeria spp. (Apicomplexa: Eimeriidae) and first molecular identification of Eimeria grenieri Yvoré & Aycardi, 1967.

Guinea fowls, Numida meleagris (L., 1758), are galliform birds native to sub-Saharan Africa, but introduced in several countries around the world for domestic breeding and/or animal production. This species is considered more resistant to disease by Eimeria spp.

CORRECTING THE NAMES OF TWO HAEMOGREGARINA SPP. FROM LIZARDS IN EGYPT.

Two haemogregarine "species" names, Haemogregarina tarentannulari and Haemogregarina rawashi, were cited by Saoud et al. (1995) as having been described by Mohammed and Ramadan (1996, in press). However, the paper by Mohammed and Ramadan (1996) was never published and, therefore, these names and their authorities must be suppressed because they violate Chapter 3 (Criteria for Publication), Article 8 (What Constitutes Published Work) of the International Code of Zoological Nomenclature.

Coccidian parasites in the endangered Forest Musk Deer (Moschus berezovskii) in China, with the description of six new species of Eimeria (Apicomplexa: Eimeriidae).

We examined 674 fresh fecal samples from forest musk deer (Moschus berezovskii Flerov) in Sichuan and Shaanxi Provinces, China, for coccidian oocysts and 65% were infected with Eimeria spp. Previously, only four Eimeria species were known from Moschus spp. Here we describe six new Eimeria species.

Biodiversity of the Coccidia (Apicomplexa: Conoidasida) in vertebrates: what we know, what we do not know, and what needs to be done.

Over the last two decades my colleagues and I have assembled the literature on a good percentage of most of the coccidians (Conoidasida) known, to date, to parasitise: Amphibia, four major lineages of Reptilia (Amphisbaenia, Chelonia, Crocodylia, Serpentes), and seven major orders in the Mammalia (Carnivora, Chiroptera, Lagomorpha, Insectivora, Marsupialia, Primates, Scandentia). These vertebrates, combined, comprise about 15,225 species; only about 899 (5.8%) of them have been surveyed for coccidia and 1,946 apicomplexan valid species names or other forms are recorded in the literature.

A novel coccidian (Apicomplexa: Eimeriidae) from Scotophilus leucogaster (Chiroptera: Vespertilionidae) in southern Saudi Arabia.

A novel species of coccidia, resembling a member of the genus Eimeria, was found in bats, Scotophilus leucogaster, collected in southern Saudi Arabia has been described on the basis of unsporulated oocysts and DNA sequencing of the Internal Transcribed Spacer 1 (ITS1) and partial 18S rDNA regions. Unsporulated oocysts of this form are ovoidal to spheroidal and had a 2-layered wall, 1.5-2.

Presence of eimerid oocysts in faeces of a quarantined dog in Iceland is explained by coprophagic behaviour prior to its importation. Case report.

Background: All dogs imported into Iceland must undergo mandatory quarantine in a special station before introduction into the country. A faecal sample is collected from the first stool passed by the dog in this station and subsequently examined for the presence of intestinal parasite stages.

Case Presentation: In May 2019 unsporulated oocysts were detected in faeces from a 7-year-old household dog that had been imported from Sweden.

The Coccidia (Apicomplexa) of the Archosauria (Crocodylia: Eusuchia) of the World.

The order Crocodylia (suborder Eusuchia) includes 27 species of alligators, caimans, crocodiles, and gharials that are cosmopolitan in distribution, inhabiting subtropical and tropical locations. Numerous surveys (many of them trivial, with small sample sizes) have reported a wide variety of blood and intestinal apicomplexans from 17/27 (63%) crocodilian hosts, but neither a summation for the group nor a revisionary systematic approach to species evaluation has ever been provided. Herein, we summarize information on the 16 species of apicomplexans that we consider to be valid, including 8 , 1 (that eventually may be transferred to ), 4 , 2 , and 1 species.

PREVALENCE AND PARASITE COMPOSITION OF GASTROINTESTINAL PARASITES IN THE ENDANGERED TIBETAN ANTELOPE () FROM THE CALVING GROUND OF HOH XIL NATURE WORLD HERITAGE SITE, QINGHAI, CHINA.

Our objective was to provide baseline information on the gastrointestinal parasites of the female Tibetan antelope () on its calving ground at the Zhuonai Lake region, in the Hoh Xil Nature World Heritage site, Qinghai, China. On 3 July 2018, 238 freshly deposited fecal samples were collected from the calving grounds and analyzed by flotation technique to recover eggs, oocysts, and nematode larvae. All fecal samples demonstrated the presence of gastrointestinal parasites: 93% (221/238) had nematodes, 36% (86/238) had cestodes, and 99% (235/238) had coccidian oocysts.
