Dogs are the primary reservoirs of Leishmania infantum ( L. infantum ), but Leishmania tropica ( L. tropica ) infection is also possible in dogs and can transmitted to humans. The southeast of Iran experiences a high prevalence of canine leishmaniasis (CanL), and veterinarians frequently encounter symptomatic cases. Therefore, from December 2017 to November 2022, the present case series was designed to assess the prevalence of CanL in owned dogs with cutaneous manifestations resembling CanL. A total of 500 owned dogs with dermal lesions from two endemic cities, Zabol and Kerman, were enrolled. Impression smears from skin lesions and popliteal lymph nodes were prepared from all cases, whereas blood samples were gathered from amastigote-positive dogs for serological and molecular surveys. Commercial ELISA was done on sera samples, and two-step nested PCR was used on extracted DNA to amplify variable fragments of the Leishmania species’ kinetoplast DNA (kDNA). Leishman bodies were microscopically detected in 7.2% (36/500) of dermal smears. Of the 360 owned dogs from Zabol, 2 have been diagnosed with L. tropica , and 10 have been diagnosed with L. infantum . Out of 140 owned dogs from Kerman, 8 were identified with L. tropica infection, and 16 were infected with L. infantum . Molecular results revealed the presence of 750 full dual-band bases related to the L. tropica species in 10/36 (27.7%) cases, which showed a considerable increase in canine cutaneous leishmaniosis compared with previous studies in southeastern Iran. The noticeable prevalence of L. tropica in owned dogs indicated that the dog’s role in cutaneous leishmaniosis should be re-evaluated as a possible animal reservoir in endemic areas.
