Genetic resistance of chickens to Marek's disease

Using integrative genomics to elucidate genetic resistance to Marek's disease in chickens.

While rearing birds in confinement and at high density are very successful practices for producing poultry meat and eggs, these conditions may promote the spread of infectious diseases. Consequently, the poultry industry places greatemphasis on disease control measures, primarily at the animal husbandry level. The field of genomics offers great promise to complement these current control measur...

Integrated genomic approaches to enhance genetic resistance in chickens.

The chicken has led the way among agricultural animal species in infectious disease control and, in particular, selection for genetic resistance. The generation of the chicken genome sequence and the availability of other empowering tools and resources greatly enhance the ability to select for enhanced disease resistance via genetic markers and to understand more deeply the biological basis of ...

Identification of Genetic Sources of Resistance to the Seed-Born Leaf Stripe Disease of Barley (Pyneophera graminea Ito & Kurib)

Extended Abstract Introduction and Objective: Leaf stripe disease of barley is caused by the seed transmitted hemi-biotrophic fungus Pyneophera graminea which has spread in to important areas of barley production in Iran especially in Khorasan Razavi province. The fungus survives as a mycelium in the pericarp, the hull and the seed coat, but not in the embryo. During the seed generation, its g...

Breeding Cattle for Genetic Resistance to Disease

Natural mechanisms of controlling lymphotropic herpesvirus infection (Marek's disease) in the chicken.

Four categories of natural resistance phenomena against Mareks disease in chickens, i.e., maternal antibody, age resistance, genetic resistance, and natural immunization, are described. In nature, these forms of resistance probably act in concert through comlex interrelationships. The mechanisms are not well understood but include humoral immunity (maternal antibody), cell-mediated immunity, an...
