[Helminth fauna of Syrian cattle].

In this work the stomach and the small intestine of 34 and the large intestine of 4 more cattle were examined. 91,17% of the examined cattle (31 in 34 animals) had infected the stomach and/or the small intestine by parasites. 14 kinds of nematodes were found. The average intensity of infection of the stomach was higher than that of the small intestine. With the exception of higher infection in 3 stomachs and 2 small intestines the intensity of infection in all other cases was from small to medium in number. In contrast to this the frequency of infection was higher in small intestines than in stomachs.--The frequency of the found nematodes was: Ostertagia ostertagi 61,76%, Cooperia oncophora 61,76%, Cooperia punctata 47,05%, Trichostrongylus axei 41,17%, Cooperia zurnabada 38,23%, Bunostomum phlebotomum 20,58%, Haemonchus contortus 17,64%, Trichostrongylus vitrinus 11,76%, Skrjabinagia lyrata 5,88%, Trichostrongylus colubriformis, Trichostrongylus longispicularis, Parabronema skrjabini and Toxocara vitulorum each 2,94%.--According to the accessible literature Skrjabinagia lyrata, Ostertagia ostertagi, Trichostrongylus longispicularis, Cooperia punctata, Cooperia zurnabada, Bunostomum phlebotomum and Trichuris discolor were first found in Syrian ruminants. The helminths of Syrian ruminants which have become known until today are tabulated.
