Coccidiosis is a ubiquitous intestinal protozoan infection of poultry seriously impairing the growth and feed utilization of infected animals. Conventional disease control strategies have relied on prophylactic medication. Due to the continual emergence of drug resistant parasites in the field and increasing incidence of broiler condemnations due to(More)
An Eimeria tenella microneme recombinant gene (EtMIC2) and encoded protein were evaluated as potential vaccines against avian coccidiosis. In ovo inoculation with the EtMIC2 gene increased anti-EtMIC2 antibody titers at days 10 and 17 following E. tenella infection. In addition, vaccinated birds developed protective immunity against infection by E. tenella(More)
Epidemiology of Eimeria species in poultry flocks is important to increase the effectiveness of vaccinations and prophylactic strategies on chicken farms. In this study, fecal samples from 356 chicken farms were collected randomly and examined for the prevalence of Eimeria species. Through microscopic examination, it was determined that 78.7% of the tested(More)
Our previous study demonstrated that chickens immunized subcutaneously with an Eimeria recombinant profilin protein vaccine emulsified in a Quil A/cholesterol/DDA/Carbopol (QCDC) adjuvant developed partial protection against experimental avian coccidiosis compared with animals immunized with profilin alone. Because in ovo vaccination is presently used in(More)
Aloes have been widely used for a broad range of pharmacological activities, including parasitic problems. Avian coccidiosis is the most costly and wide-spread parasitic disease in the poultry industry, and has been mainly controlled by the use of chemotherapeutic agents. Due to the emergence of drug-resistant strains, alternative control strategies are(More)
BACKGROUND Obesity is a health hazard that is associated with a number of diseases and metabolic abnormalities, such as type-2 diabetes, hypertension, dyslipidemia, and coronary heart disease. In the current study, we investigated the effects of Citrus aurantium flavonoids (CAF) on the inhibition of adipogenesis and adipocyte differentiation in 3T3-L1(More)
Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that plays an important role in host defense against a variety of microorganisms including protozoan parasites. Interestingly, some microbial pathogens also express a MIF-like protein, although its role in disease pathogenesis is not well understood. The aim of this study was to(More)
The effects of anethole on in vitro and in vivo parameters of chicken immunity during experimental avian coccidiosis were evaluated. Anethole reduced the viability of invasive Eimeria acervulina sporozoites after 2 or 4 h of treatment in vitro by 45 and 42%, respectively, and stimulated 6.0-fold greater chicken spleen cell proliferation compared with(More)
Anticoccidial effects of green tea (GT)-based diets were evaluated in chickens following oral infection with Eimeria maxima an ubiquitous intestinal parasite of poultry that impairs the growth and feed efficiency of infected birds. Five-week-old chickens were assigned to four groups (GT 0.5%, GT 2.0%, untreated/infected and non-infected control) and each(More)
The chicken IL-15 gene was recently cloned and shown to encode a polypeptide with T cell growth factor activity similar to IL-2. To further characterize the chemical and biological properties of chicken IL-15, we generated a panel of monoclonal antibodies against bacterially expressed protein and characterized their binding specificities. All antibodies(More)
