Research Project: Evaluation of Salmonella-Expressing Eimeria Antigens as a Vaccination Method Against Avian Coccidiosis

Location: Animal Parasitic Diseases Laboratory

Project Number: 8042-32000-111-02-T
Project Type: Trust Fund Cooperative Agreement

Start Date: Oct 1, 2013
End Date: Sep 30, 2018

Objective:
The objective of this research is to test harmless Salmonella-expressing Eimeria antigen as a way to vaccinate chickens against avian coccidiosis.

Approach:
Salmonella-expressing Eimeria antigens will be cultured in the laboratory, and inoculated into day-old chickens. After 4 weeks, immunized chickens (and controls) will be given a challenge infection with Eimeria oocysts. Weight gain and feed conversion efficiency will be measured in all chickens as a measure of protective effects elicited by the Salmonella-expressing Eimeria antigens.
