AI Article Synopsis
- - Cutaneous leishmaniasis (CL) is a parasitic skin disease endemic to Iran’s Khorasan province, with both anthroponotic and zoonotic forms occurring in the area, though some locations still lack clear data on their leishmaniasis molecular map.
- - In a study of 120 patients with suspected CL in Khaf, direct microscopy confirmed 45% of samples were positive, while PCR revealed 55% showed Leishmania species, predominantly L. tropica.
- - The findings indicate both CL forms are present in Khaf, with L. tropica being the main cause of ACL; further research is needed to identify potential reservoirs and vectors for L. major in the region.
Article Abstract
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.

Cutaneous leishmaniasis (CL) is an infection caused by the Leishmania protozoa, which are primarily transmitted through bites of infected female sandflies. This article provides a comprehensive overview of the clinical management of CL, including an in-depth analysis of its epidemiology, prevention and control measures, diagnostic modalities - particularly molecular and serological, differential diagnosis with other lesions, and treatment options. Also discussed are recent concerns regarding the endemicity of CL, with a focus on the significant rise in travel-related cases as well as locally acquired cases, providing insight into the changing epidemiological landscape.

Cutaneous leishmaniasis (CL) is a tropical disease that can cause chronic lesions and leave life-long scars, leading to social stigmatization and psychological disorders. Using growth factors and immunomodulatory agents that could accelerate wound healing and reduce the scar is highly demanded. Epidermal growth factor (EGF) plays an essential role in wound healing.

This study aimed to standardize qPCR techniques using these molecular markers kDNA and 18S rDNA across three sample types: peripheral blood, guanidine-treated blood, and tissue. The secondary objective is to evaluate the performance of 18S rDNA target in samples from 46 patients with confirmed tegumentary leishmaniasis. After obtaining the standard curve from reference strains with Leishmania, qPCR curves were standardizations and the Cts results of the patient samples were described using abstract measures.

Leishmania (Viannia) braziliensis causes cutaneous and mucocutaneous leishmaniasis. Macrophages are host cells for parasite replication and act as effector cells against the parasite. The two main macrophage phenotypes (M1 and M2) and their polarisation states have been implicated in Leishmania infection despite scarce data on L.
