Histological Appearance of Echinococcus Granulosus in the Camel Species in Algeria

Abstract

The work is realized on five livers and lungs, the organs are taken from 07 camels of female gender, they are over 7 years old, 6 of them suffers from hydatidosis. The method is based on the classical techniques, that is histology, fixation, realization of inclusion, sections, blades confection, deparaffination, rehydration, staining, dehydration, editing, and reading of the blades. Knowing that the average diameter of the hydatid cyst varies between 0.5 and 1.3 Cm and the pulmonary cysts varies between 1.5 and 2.2 cm, the results shows that the hydatid cyst wall is composed of the proligerous membrane, the laminated membrane and the perikyste. The connection between the parasite and the intermediate host tissue caused local inflammation of a granulomatous type, a fact described even in other ruminants, cysts are observed in the early stage of degeneration and necrosis, with a large number of eosinophils observed outside lymphocytes. Finally histological hydatid cyst in the camel species allows us to identify the various constituent layers of the major parasite (Endokyste, Ectokyste and Perikyste) and know the local reaction between host and parasite, with appreciation fertility cyst to the naked eye on lung and liver, and to distinguish the difference between the other species on cyst size and thickness of the layers.
