Sandßies collectedbetweenApril 2003 andNovember 2004 atTallilAirBase, Iraq,were evaluated for the presence of Leishmania parasites using a combination of a real-time Leishmaniageneric polymerase chain reaction (PCR) assay and sequencing of a 360-bp fragment of the glucose6-phosphate-isomerase (GPI)gene.A total of 2,505pools containing 26,574 sandßieswere testedusing the real-time PCR assay.Leis...

We report experimental infection and transmission of Leishmania tropica (Wright), by the blood-feeding sand fly Phlebotomus duboscqi (Neveu-Lemaire). Groups of laboratory-reared female sand flies that fed "naturally" on L. tropica-infected hamsters, or artificially, via membrane feeding device, on a suspension of L. tropica amastigotes, were dissected at progressive time points post-feeding. Ac...

BACKGROUND Cutaneous leishmaniasis (CL) is a major public health problem in Libya. The objective of this study was to investigate, for the first time, epidemiological features of CL outbreaks in Libya including molecular identification of parasites, the geographical distribution of cases and possible scenarios of parasite transmission. METHODOLOGY/PRINCIPAL FINDINGS We studied 450 patients th...

BACKGROUND & OBJECTIVES Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance underlines the importance of discovering new therapeutic products. The present study aims to investigate the in vitro antileishmanial activity and cytotoxicity of the ethanolic extract of Berberis vulgaris fruits and chloroform extract of Nigella sativa seeds against Leishmania...

introduction: anthroponotic cutaneous leishmaniasis (acl) is still a major public health problem in the northeast and central parts of iran. this study was designed to compare microscopy and cultivation methods with pcr amplification of kinetoplast dna and its1 followed by rflp analysis for diagnosis of acute and chronic acl. methods: in this study, 66 patients with acl including 24 acute and 4...

Leishmania tropica (cutaneous leishmaniasis) can be detected easily, rapidly, and conveniently by the examination of a skin ulcer smear that is stained with a modified method of Wright staining of blood (ie that used for routine hematological examinations).

background: cutaneous leishmaniasis (cl) is one of the most important neglected tropical diseases and a major public health challenge in iran caused by leishmania spp and transmitted by phlebotomine sand flies. the number of cl cases has shown an increasing pattern all over the country, including the district of varamin, southeast of tehran, iran. this study aimed to identify the leishmania spp...

General Considerations The most common etiologic agents of VL are 3 species of the L. donovani complex: Leishmania donovani donovani and Leishmania donovani infantum in the Indian subcontinent, Africa, China, the Mediterranean littoral, and the Middle East; and Leishmania donovani chagasi in South America. (Hereafter, organisms will be identified only by genus and species; eg, L. donovani for L...

The ability of the sand fly Phlebotomus (Adlerius) arabicus to transmit Leishmania tropica was studied experimentally using hyraxes (Procavia capensis), natural reservoir hosts of the parasite. Sand flies became infected with L. tropica after feeding on a lesion of needle-inoculated hyrax. Moreover, P. arabicus fed with L. tropica promastigotes transmitted the parasite to hyraxes by bite during...
