The threat of Marek’s disease virus is expanding
Marek’s disease looms as a serious concern to chicken producers, particularly in the context of high-intensity production facilities.
Researchers are beginning to breed poultry for genetic resistance to Marek’s disease as a way of complementing available vaccines and biosecurity programs.
Because the Marek’s disease virus appears to be growing more virulent, researchers are taking several approaches to identify disease-resistance genes in host poultry species.
