Infections caused by parasites belonging to the superfamily Filarioidea are regarded of clinical importance in the medical field, A considerable number of publications and reviews dealing with these infections in man has appeared during the past few decades. The more recent ones include a number of technical reports by the World Health Organization on onchocerciasis, Wuchereria and Brugia infections and human filariasis in general (WHO, 1966, 1967, 197^)» and a treatise by Nelson (1970) on ’river blindness’ of man caused by Onchocerca volvulus, However, in the veterinary field, the situation appears to be reversed as there has been a paucity of such reviews especially on filarial infections of livestock. It seems necessary, therefore, that a review be initiated along this line in order that the role played by these infections can be elucidated. The object of this paper will then be to consider the infections caused by a number of filarial nematodes in domestic ruminants. The species belonging to the genera Parafilarias Stephanofilaria, Onchocerca, Setaria and Elaeophora will be reviewed in the light of morphologic and taxonomical, epidemiological and clinico-pathological information available on them. The significance of these parasites and the possible control measures which can be instituted against them will be discussed.
