A survey on endoparasites in wild rodents of the Jaz Murian depression and adjacent areas, southeast of Iran

Abstract

In this survey, rodents and their endoparasites were investigated in the Jaz Murian depression and adjacent areas, southeast Iran. In total, 146 specimens of rodents belong to 13 species were trapped. In general, 10 different genera of endoparasites including 11 species were collected. The endoparasites were identified as follows: (1) Nematodes: Trichuris muris, Syphacia obvelata, Labiostomum sp., Labiostomum naimi, Mastrophorus muris, Aspicularis tetraptera and Heligmosomoides skrjabini, Physaloptera sp. (2) Cestodes: Choanotaenia sp., Raillietina sp., and Hymenolepis diminuta. Of 146 captured rodents, Tatera indica was found with high parasitic infestation (with 93% infested) comparing to Acomys dimidiatus (66%), Rattus rattus (50%), Meriones libycus (15%), Jaculus blanfordi (14%) and Mus musculus (8%) whereas, seven rodent species, Nesokia indica, Gerbillus nanus, Golunda ellioti, Calomyscus hotsoni, Apodemus witherbyi, Cricetulus migratorius and Microtus mystacinus were free from any parasitic infestation. Those six infested rodent species were collected from the center of the Jaz Murian depression, whereas seven non-infested rodents’ species except N. indica and G. nanus live in the marginal ranges of the Jaz Murian depression, therefore, these species inhabiting the central parts were supposed to be more important from the health aspect. The species, Labiostomum naimi collected from A. dimidiatus is the first report of this species in rodents from Iran.
