Assertion (A): Eimeria tenella is the most pathogenic coccidia of chickens and causes heavy mortality in broilers managed under deep liter system.
Reason (R): Mortality in caecal coccidiosis usually occurs due to the presence of large number of gametogenic stages in the caecal epithelium of infected birds.

It is exceptionally large and causes severe hemorrhage when it ruptures, releasing thousands of merozoites and destroying the surrounding blood vessels.
