Wild rodents and their ectoparasites in Baluchistan area, southeast of Iran

During 2008-2009 a total of 67 individuals of rodents, Tetera indica, Meriones hurrianae, Meriones libycus and Gerbillus nanus were trapped in three areas, Bampor, Daman and Qasre Qand from Iranshahr and Nikshahr districts. There is a significant difference between comparative abundance of four species (P<0.05). A total of 1422 ectoparasites collected including 299 mites (21%), 127 fleas (8.9%), 972 lice (68.4%) and 24 ticks (1.7%). Significant findings amongst the ectoparasites is the lice group with three species identified, Laelaps accuninata, Andralaelaps hermophrodita and Paracheylaellaps pyriformis being the first record in the study areas. All four captured genera of rodents are known as main/ potential reservoir hosts of zoonotic cutaneous leishmaniasis. The migration habit of rodents may affect the spatial distribution of parasitic ticks and their transmitted diseases like CCHF, which has been reported in recent years from Sistan and Baluchestan province. Monitoring of rodent populations and their ectoparasites will help to predict the potential of zoonotic arthropod-borne diseases.
