Photomicrographs of chicken ileum sections stained with hematoxylin and eosin. Alcian Blue was used to stain the goblet cells. A) Normal ileum histological structure of non-challenge treatment (NC) (200X); B) Challenged treatment (CH) (200x) 1. Higher lamina propria thickness; 2. Inflammatory cell infiltration in the lamina propria; 3. Presence of oocysts; These alterations contributed to the highest ISI index (P< 0.05) in coccidiosis challenged group at 21 days in comparison to the non-challenged group.
