Abstract 1 Eimeria tenella is the causative agent of coccidiosis in poultry. Infection of chicken 2 intestine begins with ingestion of sporulated oocysts releasing sporocysts which in turn 3 release invasive sporozoites. The monoclonal anti...

The surface antigen 1 of Toxoplasma gondii (TgSAG1) is a major immunodominant antigen and is widely considered an ideal candidate for the development of an effective recombinant vaccine against toxoplasmosis. Eimeria tenella, an affinis apicomplexan parasite with T. gondii, is a potential vaccine vector carrying exogenous antigens that stimulates specific immune responses. Here, we engineered T...

Anti-coccidial effects of the fruits of Tribulus terrestris (Tribuli fructus) ethanol extract (TTE) were studied with animal experiment following per oral administration with Eimeria (E.) tenella. This experiment was performed on the 3-day-old chicks (n=30). The animals were divided with 3 groups; TFE 15mg per animal+infected (n=10), TTE untreated+infected (n=10) and non-infected control (n=10)...

Phytochemical screening of the crude methanolic leaf extract Vernonia amygdalina was carried out. The and its fractions were tested for in vitro anticoccidial efficacy against unsporulated oocysts Eimeria tenella by oocyst sporulation inhibition model a 96-well microtitre plate. analysis revealed presence alkaloids, tannins, saponins, glycosides, triterpenoids. Different concentrations extracts...

Background: Sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of Sarcocystis genus. The major aim of this study was to determine the prevalence of Sarcocystis spp. in meat produced in Yazd, central Iran with special reference to species identification, using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).  ...

The expression levels of mRNA encoding a panel of 28 chicken cytokines and chemokines were quantified in intestinal lymphocytes following Eimeria acervulina and Eimeria tenella primary and secondary infections. Compared with uninfected controls, transcripts of the pro-inflammatory cytokines IFN-alpha, IL-1beta, IL-6, and IL-17 were increased up to 2020-fold following primary infection. By contr...

The genus Eimeria belongs to the phylum Apicomplexa, which includes many obligate intracellular protozoan parasites of man and livestock. E. tenella is one of seven species that infect the domestic chicken and cause the intestinal disease coccidiosis which is economy important for poultry industry. E. tenella is highly pathogenic and is often used as a model species for the Eimeria biology stud...

The trisubstituted pyrrole 4-[2-(4-fluorophenyl)-5-(1-methylpiperidine-4-yl)-1H-pyrrol-3-yl]pyridine (compound 1) has in vivo activity against the apicomplexan parasites Toxoplasma gondii and Eimeria tenella in animal models. The presumptive molecular target of this compound in E. tenella is cyclic GMP-dependent protein kinase (PKG). Native PKG purified from T. gondii has kinetic and pharmacolo...

The different genera currently classified into the family Sarcocystidae include parasites which are of significant medical, veterinary and economic importance. The genus Sarcocystis is the largest within the family Sarcocystidae and consists of species which infect a broad range of animals including mammals, birds and reptiles. Frenkelia, another genus within this family, consists of parasites ...
