چکیده
INTRODUCTION The study analyzed positivity of polymerase chain reaction (PCR) on detection of DNA from Leishmania in patients' samples. METHODS Extracted DNA was submitted to L150/L152, 13Y/13Z, and seminested PCR (snPCR). RESULTS Results were evidenced by bands of approximately 120, 720, and 670 bp for L150/L152, 13Y/13Z, and snPCR, respectively. L150/L152, 13Y/13Z, and snPCR positivity indexes were 76.9, 56.4, and 9.2 (p>0.05), respectively, for suspected and 93.7, 68.7, and 84.4 (p<0.05), respectively, for confirmed. CONCLUSIONS Preliminary results showed that these assays, mainly L150/L152 and snPCR, can detect Leishmania DNA and carry potential on laboratory diagnosis of leishmaniasis.

Detection of Leishmania DNA in paraffin embedded specimens of chronic lupoid leishmaniasis using polymerase chain reaction
Background: Chronic lupoid leishmaniasis (CLL) is a chronicform of cutaneous leishmaniasis that is usually resistant to antileishmania agents and leishmania is not seen in the histologicsections. We used polymerase chain reaction (PCR) to detectleishmania DNA in CLL specimens.Method: This descriptive cross sectional study was done on20 paraffin embedded specimens of CLL cases referred to theder...
متن کاملDetection of Leishmania major using PCR-ELISA
Background and objectives: Cutaneous leishmaniasis is endemic in most areas of Iran, and the diagnosis of its species is essential for controlling the disease. Leishmania major is the causative agent for cutaneous leishmaniasis in humans. Molecular methods are generally more sensitive than microscopic methods. The present study aimed to use a polymerase chain reaction-enzyme linked immunosorben...
متن کاملPolymerase chain reaction detection of Leishmania DNA in skin biopsy samples in Sri Lanka where the causative agent of cutaneous leishmaniasis is Leishmania donovani
Leishmania donovani is the known causative agent of both cutaneous (CL) and visceral leishmaniasis in Sri Lanka. CL is considered to be under-reported partly due to relatively poor sensitivity and specificity of microscopic diagnosis. We compared robustness of three previously described polymerase chain reaction (PCR) based methods to detect Leishmania DNA in 38 punch biopsy samples from patien...

In this study, PCR assays targeting different Leishmania heat-shock protein 70 gene (hsp70) regions, producing fragments ranging in size from 230-390 bp were developed and evaluated to determine their potential as a tool for the specific molecular diagnosis of cutaneous leishmaniasis (CL). A total of 70 Leishmania strains were analysed, including seven reference strains (RS) and 63 previously t...

Background and aim: Cutaneous leishmaniasis (CL) is a health problem of many countries in tropical and subtropical regions including Iran. Isfahan province is one of the foci of CL with the highest prevalence in Iran. This study was done to identify the species of Leishmania isolated from the patients in Ghohab Mohammad Abad, located in southwest of Isfahan which is a new foci of CL. Identifica...
