A total of 12 nematode species were determined in the collection recovered from domestic ruminants in Afghanistan. Ten of them were found for the first time in this region: Trichocephalus globulosus, Trichostrongylus probolurus, Cooperia bisonis, Nematodirus spathiger, N. abnormalis, Thelazia rhodesi, Bunostomum phlebotomum, Haemonchus contortus, Dictyocaulus filaria and Oesophagostomum radiatum. Morphological and metrical characteristics of T. globulosus, T. skrjabini and C. bisonis, based on our own material, are added.
