11 Mycoplasmas have affected poultry production for many years and effective control of mycoplasma infection has been a fundamental stepping stone to improved performance and productivity. However, infections appear to be making a comeback. Numerous species of mycoplasmas have been isolated from avian sources. Two species are recognised as predominantly pathogenic to chickens and turkeys. Mycop...

Mycoplasma gallisepticum (MG) is economically important pathogen of poultry causes airsacculitis and frequently infraorbital sinusitis in turkeys. Infections may remain without clinical signs, but they can make birds susceptible to secondary infections. This study was carried out for molecular detection and phylogenetic analysis of MG infections in commercial and backyard turkey flocks in some ...

In the present work, chickens and turkeys were infected with virulent or attenuated Histomonas meleagridis to investigate and compare the effect of both isolates on birds. Thereby, histomonads of a clonal culture were propagated in vitro either for a short period of time (21 passages) to preserve virulence or for 295 passages to achieve attenuation. On the first day of life birds of each specie...

Two experiments were conducted to assay digesta viscosity and metabolizable energy values of different cereal-based diets with or without enzyme supplementation in growing turkeys and broiler chickens at 3 and 6 weeks of age and in laying hens. Age, feeding and poultry species had interacting effects on digesta viscosity and metabolizable energy. Viscosity was reduced with age in broilers, but ...

Predators elicit antipredator behaviors such as proactive and reactive movements in prey, but both are rarely investigated simultaneously. Impacts of human predation risk on can be greater than those nonhuman predators, resulting increased effects populations community structure. We compared the influence movement male Eastern wild turkeys (Meleagris gallopavo, hereafter turkey). used simultane...

The matrix (M) protein of avian pneumovirus (APV) was evaluated for its antigenicity and reliability in an enzyme-linked immunosorbent assay (ELISA) for diagnosis of APV infection, a newly emergent disease of turkeys in United States. Sera from APV-infected turkeys consistently contained antibodies to a 30-kDa protein (M protein). An ELISA based on recombinant M protein generated in Escherichia...

Recently, deoxynivalenol-3-sulfate (DON-3-sulfate) was proposed as a major DON metabolite in poultry. In the present work, the first LC-MS/MS based method for determination of DON-3-sulfate, deepoxy-DON-3-sulfate (DOM-3-sulfate), DON, DOM, DON sulfonates 1, 2, 3, and DOM sulfonate 2 in excreta samples of chickens and turkeys was developed and validated. To this end, DOM-3-sulfate was chemically...

The aim of the research was to determine the efficiency of in ovo immunisation of turkeys against the haemorrhagic enteritis virus, while simultaneously applying a synthetic immunomodulator – methisoprinol – by the same route of administration. Dindoral SPF vaccine, in a dose of 0.1 ml of the solution prepared ex tempore after dissolving the vaccine in 100 ml of water for injection, and methiso...

BACKGROUND Avian Metapneumovirus (aMPV) infections are a huge economical issue for the poultry industry worldwide. Although maternal antibodies do not protect turkey poults against turkey rhinotracheitis (TRT), almost no studies have been conducted so far regarding the impact of these antibodies on vaccine induced immunity development against aMPV infection. We conducted four experiments on com...
