Ann. Méd. Vét., 2007, 151 (3), pp 200-206 Histopathologic study of cattle rumen infested by Carmyerius marchandi
(Gastrothylacidae) and by Paramphistomum microbothrium (Paramphistomidae), in Southern SenegalSECK M. T., MARCHAND B., BA C.T.Abstract :
The paramphistomosis is endemic in the Kolda region, located at the south of Senegal. The genus Carmyerius (Gastrothylacidae), and Paramphistomum
(Paramphistomidae), in particular,
parasitize cattle. A macroscopic and microscopic study morphological comparative of the wall of six rumens infested compared with a control group
of three rumens is proposed.
The six rumens parasitized used for this study are infested by only one species of parasite: three by Paramphistomum microbothrium; three others by Carmyerius
marchandi.
Carmyerius marchandi is more pathogenic than Paramphistomum microbothrium, because it is haematophagous.
Both parasites, in their final micro-habitat represented by the rumen, cause a destruction of the papillae, a hyperplasia of the epithelium and an inflammatory reaction. These lesions are more or less significant according to
the species of the parasite identified.
The rumens in the control group were free of lesions.
In Senegal, as in other countries of Africa, paramphistomosis is seldom letal, but it is always responsible for a weakened general condition of the herds, causing an economic problem. Get the PDF Contact person : mtseck@hotmail.fr |
