A study was made in rural regions around Neiriz city, Fars province in the south of the Islamic Republic of Iran during 2002–03 to further investigate a new focus of zoonotic cutaneous leishmaniasis. Meriones libycus was the dominant rodent (100% of 65 rodents collected) and 4.6% were naturally infected with the amastigote form of Leishmania spp. Promasigotes were identified as L. major. This confirms M. libycus as the main reservoir host of zoonotic cutaneous leishmaniasis in southern parts of the country.
