Among the enteric diseases controlled by antibiotics, avian coccidiosis and necrotic enteritis (NE) together cost the poultry industry more than $12 billion annually. Clostridium perfringens is the causative agent of NE, and coccidiosis is caused by several species of Eimeria protozoa. In this objective, we will use an “immuno-proteome approach” to prevent and mitigate coccidiosis and NE in chickens. We will also develop a “phytochemical-based strategy” to reduce NE-induced gut damage as well as optimize gut health.

As our publications related to this goal are produced, we will include them on this page.
