in vitro evaluation of the efficiency of Artemisia judaica leaf extract on sporulation of Eimeria papillate oocysts and its cytotoxicity [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Eimeria is the parasite that is responsible for eimeriosis in the gut of numerous domestic mammals. While treating eimeriosis, the use of medication and some effects of synthetic anticoccidials has led to the development of resistant parasites ...

Proteomic Analysis of Fractionated Eimeria tenella Sporulated Oocysts Reveals Involvement in Oocyst Wall Formation

International Journal of Molecular Sciences, 2023
Eimeria tenella is the most pathogenic intracellular protozoan parasite of the Eimeria species. Eimeria oocyst wall biogenesis appears to play a central role in oocyst transmission. Proteome profiling offers insights into the mechanisms governing the molecular basis of oocyst wall formation and identifies targets for blocking parasite transmission ...

Administering Eimeria maxima oocysts through drinking water improves coccidiosis vaccine uptake in broiler chickens

Journal of Applied Poultry Research, 2023
SUMMARY: Vaccination against avian coccidiosis is increasingly being used by the poultry industry to prevent outbreaks of this parasitic disease, but problems with nonuniform administration of Eimeria oocysts by spray vaccination at the hatchery is ...

Defining stage-specific activity of potent new inhibitors of Cryptosporidium parvum growth in vitro [PDF]

, 2020
Currently, nitazoxanide is the only FDA-approved treatment for cryptosporidiosis; unfortunately, it is ineffective in immunocompromised patients, has varied efficacy in immunocompetent individuals, and is not approved in infants under 1 year of age ...

Studies on coccidian oocysts (Apicomplexa: Eucoccidiorida) [PDF]

Revista Brasileira de Parasitologia Veterinária, 2014
The oocysts of the coccidia are robust structures, frequently isolated from the feces or urine of their hosts, which provide resistance to mechanical damage and allow the parasites to survive and remain infective for prolonged periods. The diagnosis of coccidiosis, species description and systematics, are all dependent upon characterization of the ...

Enzymes as Feed Additive to Aid in Responses Against Eimeria Species in Coccidia-Vaccinated Broilers Fed Corn-Soybean Meal Diets with Different Protein Levels [PDF]

, 2007
This research aimed to evaluate the effects of adding a combination of exogenous enzymes to starter diets varying in protein content and fed to broilers vaccinated at day of hatch with live oocysts and then challenged with mixed Eimeria spp. Five hundred

Toxoplasma gondii Oocyst–specific Antibodies and Source of Infection

Emerging Infectious Diseases, 2010
Infection source can determine cost-effective public health interventions. To quantify risk of acquiring Toxoplasma gondii from environmental sources versus from meat, we examined serum from pregnant women in Chile.

Goussia trichogasteri n. sp. (Apicomplexa: Eimenidae) infecting the aquarium-cultured golden gourami Trichogaster trichopterus trichopterus [PDF]

, 1992
Goussia trichogasteri n. sp. is described from the gut of the aquarium fish Trichogaster trichopterus trichopterus. Gamogonic stages develop epicellularly in the gut epithelium. Oocysts are shed in early stage of sporulation.

A new pathogen transmission mechanism in the ocean: the case of sea otter exposure to the land-parasite Toxoplasma gondii. [PDF]

, 2013
Toxoplasma gondii is a land-derived parasite that infects humans and marine mammals. Infections are a significant cause of mortality for endangered southern sea otters (Enhydra lutris nereis), but the transmission mechanism is poorly understood.
