Variable protection against experimental broiler necrotic enteritis after immunisation with the C-terminal fragment of Clostridium perfringens alpha-toxin and a non-toxic NetB variant [PDF]

, 2016
Necrotic enteritis toxin B (NetB) is a pore-forming toxin produced by Clostridium perfringens and has been shown to play a key role in avian necrotic enteritis (NE), a disease causing significant costs to the poultry production industry worldwide.

EIMERIA SPECIES FROM CRYPTOTIS SHREWS (INSECTIVORA: SORICIDAE) WITH DESCRIPTION OF A NEW SPECIES

Journal of Parasitology, 2003
Fresh fecal samples from 12 shrews, 10 Cryptotis goodwini Jackson, 1933, and 2 Cryptotis merriami Thomas, 1898, were collected between December 1994 and May 1998; 11 (92%) were positive for eimeriid coccidia, including 8 of 8 C. goodwini and 2 of 2 C. merriami from Honduras and 1 of 2 C. goodwini from Guatemala.

Molecular diagnosis of Eimeria species affecting naturally infected Gallus gallus

Genetics and Molecular Research, 2011
We used PCR to test various protocols and define a technique for DNA extraction directly from chicken-shed stool samples for the identification of Eimeria species that parasitize birds. It was possible to extract and amplify DNA of seven Eimeria species from field stool samples, using both protocols tested; extractions made with phenol/chloroform ...

Prevalence of Cryptosporidium parvum, Giardia duodenalis and Eimeria spp. in diarrhoeic suckling calves from north-western Spain and analysis of their interactions

International Journal of Veterinary Science and Medicine
Although Cryptosporidium parvum, Giardia duodenalis and some Eimeria species are frequently involved in neonatal calf diarrhoea (NCD), detailed studies on their interactions are scarce. Therefore, a cross-sectional study including faecal samples from 404

Enzyme variation in Eimeria species of the chicken

Parasitology, 1975
A method for the biochemical identification of protozoa belonging to the genus Eimeria is described for the first time. Starch gel electrophoresis of the enzymes lactate dehydrogenase, glucose phosphate isomerase, 6-phosphogluconate dehydrogenase and glucose-6-phosphate dehydrogenase from parasite extracts revealed both intra- and inter-species ...

New Species of Genus Eimeria (Eimeria tarabaie) in Broiler Chicken from Aurangabad, Maharashtra State, India

Asian Journal of Research in Zoology, 2023
Chicken coccidiosis causes huge economic losses in the poultry industry. Genus Eimeria from phylum Apicomplexa shows extensive damage in the poultry industry. In our investigation, ten species of Eimeria were recorded among seven that were previously recorded from various parts of the world.

Efficacy of Arprinocid (MK-302) Against Eimeria Species in Broilers

Poultry Science, 1978
Eight floor pen trials were conducted to determine the effect of arprinocid on the weight, feed efficiency, and histological lesions of broiler chickens exposed to coccidiosis. In three trials, the levels of arprinocid were 0, 40, 60, 70, 80, and 90 ppm, and in the other five trials, 0, 50, 75, and 100 ppm.
