Poultry Health and Food Safety, Why Genomics Approach?
Chickens live in an environment full of microbes. Every day they are exposed to untold numbers of potentially pathogenic agents through the air, water and food they consume, and contact with other birds. Yet despite this exposure, very rarely do the birds succumb to infection. The foremost reason for this is the highly efficient early defense response of the immune system. The hallmark of an immune system is the diverse and variable responsiveness potential pathogens. It is this diversity and variability that allows the immune response to defend against multiple types of infectious agents and to eliminate these agents from the host especially in genetically homogenous populations of animals such as today’s commercial poultry industry. The immune system is a multifaceted arrangement of membranes (skin, epithelial, mucus), cells, and molecules whose function is to eradicate invading pathogens from a host. Working together, the various components of the immune system perform a balancing act of being lethal enough to kill pathogens yet specific so as not to cause extensive damage to “self tissues of the host. A functional immune system is a requirement of a “healthy life in modern animal production.
