[Additional findings on the distribution and prevalence of Tetrapetalonema (Esslingeria) streptocerca (Macfie and Corson, 1922) in West Africa (author's transl)].

Human streptocerciasis has been found in the Accra district (Ghana), in southern Ivory Coast, and in Upper Volta in migrants. During a survey in the forest part of the Volta Region (Eastern Ghana), 119 cases were discovered in ten villages between 6 degrees 50' N., and 7 degrees 50' N., indicating local transmission of the parasite. The parasitic load has always been low. In the area, the presence of T. streptocerca cannot modify the results of a direct diagnosis of onchocerciasis based on the emergence of microfilariae from skin snips in distilled water or normal saline solution. The parasite has not been found in surveys undertaken north of the 8 degrees N., neither in Ghana, nor in Togo or Ivory Coast. The presence of T. streptocerca in villages located on the Togolese border confirm that this filaria exists in Togo too, although no mention is made in the literature.
