Summary : Cutaneous onchocercosis can affect horses. Adult forms and larvae of Onchocerca are responsible for the troubles. Only a few epidemiological studies have been carried out in France on this topic. This preliminary study is aimed at establishing a method of detection of cutaneous larvae so as to perform later an epidemiological study in our country. One hundred and sixty skin biopsies were realised on horses from Poland, France and Spain in order to detect onchocerca larvae. These samples were cut into little slides, immersed in physiological solution, that was centrifuged and the residue analysed with a microscope. Six foreign horses were found positive (5/95 Polish and 1/18 Spanish). None of the forty seven horses from France was detected positive. These results are similar to the ones established by Collobert, who found a prevalence of 1% on 368 horse samples in 1995. This investigation allowed us to try a simply, reliable and not expensive detecting method, that should be used more frequently in usual practice by veterinarians.
