Abstract

Abstract: The histology (H.E), histochemistry (carbohydrates, proteins, collagen, and calcium), enzyme profile (ATPase and Acid phosphatase), and ultramorphology of the ileum of Cephalotes atratus, C. clypeatus and C. pusillus were studied in order to obtain some information about the similarities of these species. The relationship among these three species, as well as the results obtained for the wall, and the contents of this portion of the digestive tract were discussed. In C. clypeatus the ileum is quite small than C. atratus, beside the similarities of the body size. The ATPase results showed 2 different regions: the anterior resemble to responsible to absorb material from the haemolymph and the posterior one to absorb from the ileum lumen. Others histochemistry didn’t show any differences. Ours results didn’t show any information that could relation the microorganism’s population. (AU)
