چکیده

North African gundis (Ctenodactylus gundi) were trapped in the Leishmania (L.) tropica focus of cutaneous leishmaniasis, situated in southeast Tunisia and evaluated for Leishmania infection by real-time kinetoplast DNA polymerase chain reaction (PCR). Species identification was performed by internal transcribed spacer one (ITS1)-PCR-restriction fragment length polymorphism (RFLP) and high-resolution melting (HRM) analysis of the 7SL RNA gene. Real-time PCR on blood was positive in 6 of 13 (46.2%) tested gundis. Leishmania tropica was identified in five infected gundis and Leishmania major in one specimen. Alignments of the ITS-1 DNA sequences and 7S-HRM curves analysis indicated that similar genotypes were present in humans, a sandfly, and gundis from the same region suggesting a potential role of this rodent as reservoir host of L. tropica in southeast Tunisia.

Comparison of Leishmania killicki (syn. L. tropica) and Leishmania tropica Population Structure in Maghreb by Microsatellite Typing

Leishmania (L.) killicki (syn. L. tropica), which causes cutaneous leishmaniasis in Maghreb, was recently described in this region and identified as a subpopulation of L. tropica. The present genetic analysis was conducted to explore the spatio-temporal distribution of L. killicki (syn. L. tropica) and its transmission dynamics. To better understand the evolution of this parasite, its populatio...

During September 2010, 133 female sand flies were caught inside houses of patients with cutaneous leishmaniasis in the focus for this disease in southeastern Tunisia and subsequently dissected. One specimen was positive for Leishmania protozoa. This sand fly species was identified as Phlebotomus sergenti, and the parasite was identified as L. tropica. This is the first report of P. sergenti inv...

Determination of Leishmania species causing cutaneous leishmaniasis in Mashhad by PCR-RFLP method

Three species of L. tropica, L. major and L. infantum are known as main causal agents of leishmaniasis have been reported in Iran. Since cutaneous leishmaniasis (CL) is endemic in North East of Iran, in the present work, 50 Leishmania positive isolates from human cases in Mashhad (Center of Razavi province, North East of Iran), were genotyped by means of polymerase chain reaction-restriction f...
