From May 2010 to Sep 2010 the visceral samples of 60 wild rabbits at necropsy, selected from districts of East Azerbaijan Province, were removed, and examined for Endoparasites infestation. To identify the species of helminths, the nematodes were cleared in lactophenol (Wet-mount) and protozoans were stained using Giemsa and Trichrome staining. According to Results of present study 46.67% of rabbits infected toendoparasites were distinguished and these endoparasites was consist of Nematodirus leporis, Trichostrongylus retortaeformis,Passalurus ambigus, Cysticercus pisiformis, Eimeria magna and Eimeria steidae were distinguished. Of course in infected rabbits maximum and minimum infestation rate was belonging to Nematodirus leporis (13.33%), Eimeria magna and Eimeria steidae (3.33%) respectively. Key Word: Wild Rabbits, Endoparasites, East-Azerbaijan province, Iran. ______________________________________________________________________________ INTRODUCTION Rabbits and rodents are common features of the anatomy, but due to some unique characteristics that make up a separate category called lagomorpha. There are two pair of teeth is characterized by a high in the rabbits that will distinguish them from other rodents, and other rodents are a pair of teeth is high(4). All domesticated rabbits in the same century BC was conducted. The wild rabbits in that special place called leporaria, were recorded.Real rabbit was probably domesticated in the sixteenth century until 1700, and the hair coat of paint, seven types (mutants) were identified from the rabbit (4).
