Amino-acid malabsorption and intestinal leakage of plasma-proteins in young chicks infected with Eimeria acervulina.

The in vivo absorption of 14C-labelled amino-acids and the leakage of radioactive plasma proteins into the gut of infected birds were measured together with their food-intake and growth. The results suggested that anorexia and protein leakage from the gut are major factors in the pathogenesis of E. acervulina infection.
