Nineteen roe deer coming from Julian Prealps were investigated for the presence of abomasal nematodes. An anatomopathological analysis was also carried out. S. spiculoptera and O. leptospicularis, with their alternative morphs S. mathevossiani and O. kolchida, were the abomasal dominant species. Eleven helminthic species (as average 5.5 species/animal) were recovered. Therefore, composition of the species was typical of this wild ruminant host in Europe. Between generalist species, Haemonchus contortus shows a high prevalence and abundance (P=89.5; A=167). Due to abomasal multiparasitism, it was not possible to attribute to a single specie the anatomopathological patterns recovered. Hyperplastic-catarrhal abomasitis was presents in the animal with the highest parasitic burdens (>800adults/abomasum) and at least 5 helminthic species. This result emphasizes the pathogenic role of abomasal nematodes in roe deer and the opportunity of a wildlife management.
