Background: Leishmania infection is a serious worldwide health concern that caused by various types of parasite genus. Current therapies for this disease, including pentavalent antimonial complexes, are not safe and do have enough efficacy. The Artemisia aucheri spring leaf extract has been reported to antimicrobial effects on variety pathogens. Objective: This study aimed find how A. affects t...

BACKGROUND Infections caused by Leishmania are becoming major public health problems on a global scale. Many species of Leishmania around the world are obtaining resistance levels of up to 15 folds, as estimated by the World Health Organization. Leishmania showing resistance is relatively difficult to observe and maintain in laboratory settings. OBJECTIVES The current study deals with the gen...

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...

BACKGROUND Phlebotomus (Paraphlebotomus) sergenti is at least one of the confirmed vectors for the transmission of cutaneous leishmaniasis caused by Leishmania tropica and distributed widely in Morocco. This form of leishmaniasis is considered largely as anthroponotic, although dogs were found infected with Leishmania tropica, suggestive of zoonosis in some rural areas. METHODOLOGY AND FINDIN...

Cutaneous leishmaniasis has various phenotypic aspects consisting of polymorphic amastigotes with different genetic ranges. Samples were collected from suspected patients of Khuzestan province. Prepared smears were stained, scaled, and measured using ocular micrometer. The Cyt b, ITS-rDNA, and microsatellite genes of Leishmania were amplified and Leishmania species were identified by molecular ...

Cutaneous leishmaniasis (CL) is prevalent in the Egyptian Sinai Peninsula and previous research has consistently documented the etiologic agent to be Leishmania major. We report the first isolation of Leishmania tropica from human cases of CL in a Northern Sinai community bordering Palestine. Parasite culturing, real-time polymerase chain reaction (PCR), gene sequencing, and restriction fragmen...

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-resol...

Leishmania tropica and L. major are etiologic agents of human cutaneous leishmaniasis. Delayed type hypersensitivity (DTH) is an immunologic response that has been frequently used as a correlate for protection against or sensitization to leishmania antigen. In BALB/c mice, L. tropica infection results in non-ulcerating disease, whereas L. major infection results in destructive lesions. In order...

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...
