Coccidiosis is a parasitic disease that has a substantial negative impact on the poultry industry. It is caused by Eimeria tenella species that invade and damage intestinal epithelial cells, resulting in hemorrhagic inflammation, which ultimately leads to reduced weight gain and feed conversion, and the risk of contracting other diseases is increased due to the break down of the intestinal epithelial barrier.This study was designed to research the study of Eimeria tenella infection in broiler chickens, emphasizing pathological changes and treatment.In conclusion, the present study provides evidence to support the possibility of using L. plantarum as a promising carrier for the delivery of protective antigens to effectively protect chickens against coccidiosis
