| ABSTRACT:
Introduction & Objective: Visceral leishmaniasis (VL) is a disease commonly known as Kala-azar caused by protozoan parasites of the genus Leishmania including L. donovani, L. infantum and L. chagasi. VL is sporadic in many areas of Iran and is endemic in a few provinces such as Fars, Azarbayjan, Bushehr, Ardabil and Qom. VL has been reported from some areas of Kohgiloyeh and Boyerahmad and this study aimed to characterize the causative agent of VL in this region.
Materials & Methods: Bone marrow sample was obtained from 6 VL patients from children department in Imam Sajad hospital in Yasuj. DNA was extracted from the obtained samples and was checked by semi-nested PCR to determine the species of the parasite. To do that, a segment of minicircle kinetoplast DNA was amplified, using LINR4 and LIN17 primers. Products of PCR were evaluated by electrophoresis, using 1.5% agarose and stained with ethidium bromide.
Results: Parasitologically examination of bone marrow smears demonstrated amastigotes form of the parasite in the samples. For mass cultivation, isolated parasites were cultured in diphasic NNN followed by RPMI 1640 media. All the samples produced a 720 bp band in PCR assay. The isolates were compared with referent strains and it was revealed that all the isolates were L. infantum.
Conclusion: Findings of this study demonstrated that the causative agent of VL in Kohgiloyeh and Boyerahmad was L. infantum. Further study is needed to explore other aspects of VL in this region. |
