RESUMO
CONTEXT: Cutaneous leishmaniasis (CL) is an endemic parasitic skin disease in many parts of Iran including Khorasan province. Both clinical forms of the disease, anthroponotic cutaneous leishmaniasis (ACL) and zoonotic cutaneous leishmaniasis (ZCL) are present in this province. However, leishmaniasis molecular map is determined in four cities of Khorasan, but several foci still are remained unknown. AIM: The aim was to identify the species of Leishmania causing CL in Khaf, a District in Khorasan-e-Razavi province. MATERIALS AND METHODS: Slide smears obtained from skin lesions of 120 patients suspected to leishmaniasis. Direct microscopy and polymerase chain reaction (PCR) performed using specific kinetoplast DNA primers. Data were analyzed with the use of SPSS. RESULTS: Among 120 persons with skin ulcers suspected to CL, the results of direct smear of 54 (45%) samples were positive. PCR band were observed in 66 (55%) of examined samples in which 46 bands identified for Leishmania tropica and 20 for Leishmania major. CONCLUSION: Both ACL and ZCL are present in Khaf. L. tropica is the dominant causative species for ACL. Further study is recommended to discover probable reservoir and vector for L. major in Khaf.
