A study on gastrointestinal helminths of camels in Mashhad abattoir, Iran

Abstract

dromedarii (22%), Haemonchus longistipes (18%), Nematodirus oiratianus (16%), Cooperia oncophora (16%), Trichuris barbetonensis (10%), Parabronema skrjabini (10%), Nematodirella cameli (10%), Marshallagia marshalli (4%), Teladorsagia circumcincta (4%), Moniezia benedeni (3%), Moniezia expansa (3%) and Trichostrongylus vitrinus (2%). Nematodirella dromedarii, Trichostrongylus probolurus , Trichostrongylus colubriformis , Cooperia oncophora , and Nematodirus oiratianus , were identified from dromedary in Iran for the first time. The pathologi cal lesions in the affected abomasums, as well as s mall and large intestines, were hyperaemic and thickened mucosa with haemorrhagic foci. Histopathological examination revealed inflammatory reaction in the a bomasa, flattened mucosa and villous atrophy with inflammatory reactions composed of eosinophils and lymphocytes in the intestines, respectively. The prevalence observed in the present study indicates the necessity of using an anthelmintic drug for inc reasing the health and productivity of camels.
