Bovine farcy in the Accra Plains of Ghana.

Bovine farcy is described for the first time in Ghana in herds kept in the Aveyime area of the Accra Plains. Reasons why the disease seems confined to a small geographical area are not yet clear. Different breeds of cattle are equally affected. Mineral deficiencies were not observed in the samples taken for analysis (Ca, Mg, P, Na, K, Cl). Limited examination of tick population on cattle showed a predominance of A. variegatum. Factors enhancing the pathogenicity and persistence of the Mycobacterium are still not clear. A study is soon to start.
