Before the discovery of Toxoplasma gondii as a coccidium of the cat in 1970, cat and dog coccidia were classified in the genus Isospora and considered of little clinical or zoonotic significance. Since 1970, several new (Hammondia sp., Neospora sp.) and previously described species, including Sarcocystis, Besnoitia, and Cryptosporidium have been found as coccidians of cats and dogs with clinica...

An experiment was carried out using 200, day old unsexed broiler chicks to study the efficacy of herbal anticoccidial agent in broiler chickens. Chicks belongs to group I received control diet, group II herbal anticoccidial agent (500g/ton), group III coccidia oocysts and group IV received both herbal anticoccidial agent(500g/ton) and coccidia oocysts. The doses of 50,000 sporulated oocysts wer...

Bej§ovec, J.: Permanent Transmission of Endoparasites in Large Herds of Cattle. Acta vet. Bmo,60, 1991: 205-212. Calving houses were found to be cohtaminated with endoparasites by the first crop of pregnant cows arriving in the new premises. No significant differences were found in the incidence of endoparasite species between new and old calving houses by' artalysis of variance. The proportion...

BACKGROUND This study aimed at investigating a potential effect caused by coccidia on the immune response to vaccine- and very virulent infectious bursal disease virus (vvIBDV) in SPF chickens. METHODS Two groups of three weeks old SPF chickens were vaccinated prior to inoculation with coccidia and challenge with virulent IBDV, all within a period of eight days. Two control groups were simila...

*'IT IS PROBABLE that coccidia cause greater economic loss among domesticated animals of the temperate zone than any other group of protozoa." Thus Becker ^ aptly indicated the importance of coccidiosis, the specific disease caused by these protozoan parasites. It may be added that the coccidia probably cause greater economic loss among chickens alone than among all other domesticated animals c...

For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation. Important parasite taxa in young Soay sheep are strongyles (Trichostrongylus axei, Trichostrongylus vitrinus and Teladorsagia circumcincta), coccidia (11 Eimeria species) a...

Peritoneal exudate cells from chickens immunized with two species of coccidia, Eimeria tenella or Eimeria maxima, were examined for their capacity to phagocytose stages of the parasite in vitro. True phagocytosis of the sporozoite stage is difficult to estimate because of its ability to invade cells, but may be evaluated by comparison with control suspensions. Peak activity (compared with cells...

Large-scale screening has led to the identification of several experimental compounds that have very potent intrinsic activity against coccidia, but the lack of translation to in vivo efficacy has been a major hurdle in developing such leads into effective new drugs. We developed methods to explore the impact of oral availability and appropriate distribution in tissue, both of which are potenti...

Coccidiosis is likely the most costly disease threat to global poultry production and prevention of coccidiosis is essential in order to maintain intestinal integrity and the efficient absorption of nutrients in the chicken. Narasin is an ionophore anticoccidial. Ionophores transport cations such as sodium across the pellicle membrane of sporozoites of coccidia, resulting in a lethal osmotic im...

Coproscopic examinations of mouflons Ovis aries musimon from four forest districts of Lower Silesia performed in spring and autumn from 2012 to 2014 demonstrated the presence of pulmonary nematodes and intestinal parasites, including coccidia of the genus Eimeria. Prevalence of pulmonary nematodes (mainly Muellerius capillaris) amounted to 69.78%, intestinal nematodes--56.11% and coccidia of th...
