[Two new nodular Onchocerca spp. in wild Bovidae, in Upper Volta (author's transl)]

Description of two new Onchocerca from wild Bovidae, O. schulzkeyi n. sp. and O. hamoni n. sp., respectively parasite of Hippotragus equinus and Kobus (A.) kob; both species have been recorded in the Volta region, where human onchocerciasis is prevalent. O. schulzkeyi and O. hamoni are located in respectively, dermic and subcutaneous nodules, the females of both species are devoid of cuticular rings. Those two new species belong to the line of O. volvulus and nodular Onchocerca of Bovinae. This finding suggests that, as for O. ochengi, they can disturb the evaluation of the annual potential of transmission, necessary in the epidemiological studies concerning the human onchocerciasis.
