In Sudan human leishmaniasis occurs in different clinical forms, that is, visceral (VL), cutaneous (CL), mucocutaneous (ML), and post-kala-azar dermal leishmaniasis (PKDL). Clinical samples from 69 Sudanese patients with different clinical manifestations were subjected to a PCR targeting the cytochrome oxidase II (COII) gene for Leishmania species identification. Mixed infections were suspected...

BACKGROUND In the Indian subcontinent, about 200 million people are at risk of developing visceral leishmaniasis (VL). In 2005, the governments of India, Nepal and Bangladesh started the first regional VL elimination program with the aim to reduce the annual incidence to less than 1 per 10,000 by 2015. A mathematical model was developed to support this elimination program with basic quantificat...

OBJECTIVE To document the frequency of Leishmania donovani infection at community level in a highly endemic region in southeastern Nepal, and to assess socioeconomic and environmental risk factors. METHODS A random cross-sectional population survey was held in two visceral leishmaniasis (VL) foci in Morang District in April to May 2003, enrolling individuals 2 years or older and residing in t...

The unreliability of most of the existing antibody-based diagnostic kits to discriminate between active and treated VL cases, relapse situation and reinfection are a major hurdle in controlling the cases of Kala-azar in an endemic area. An antigen targeted diagnostic approaches can be an attractive strategy to overcome these problems. Hence, this study was focused on identifying the Leishmania ...

BACKGROUND Leishmaniasis is a spectrum of diseases with great relevance to public health. Conventional diagnostic methods are time consuming, needing trained personnel. A robust, rapid and cost effective diagnostic test is warranted for on-time diagnosis and field application. METHODS We have developed a loop mediated isothermal amplification (LAMP) assay with primers (n = 6) based on Leishma...

Abstract Background Asymptomatic Leishmania infections outnumber clinical on the Indian subcontinent (ISC), where disease reservoirs are anthroponotic. Diagnostics which detect active asymptomatic infection, suitable for monitoring and surveillance, may be of benefit to visceral leishmaniasis (VL) elimination campaign ISC. Methods Quantitative polymerase chain reaction (qPCR), loop-mediated iso...

BACKGROUND Visceral leishmaniasis (VL) is a parasitic infection (also called kala-azar in South Asia) caused by Leishmania donovani that is a considerable threat to public health in the Indian subcontinent, including densely populated Bangladesh. The disease seriously affects the poorest subset of the population in the subcontinent. Despite the fact that the incidence of VL results in significa...

Visceral leishmaniasis (VL, kala-azar) is a zoonotic infection caused by Leishmania species which are transmitted to humans by the bites of infected female phlebotomine sandflies. Leishmania infantum is the responsible species of VL in Aegean, Mediterranean, and Central Anatolia regions of Turkey mainly observed sporadically in pediatric age groups. The aim of this study was to evaluate the cli...

BACKGROUND Little is known about the parasite/host factors that lead to Post Kala-azar Dermal Leishmaniasis (PKDL) in some visceral leishmaniasis (VL) patients after drug-cure. Studies in Sudan provide evidence for association between polymorphisms in the gene (IFNGR1) encoding the alpha chain of interferon-γ receptor type I and risk of PKDL. This study aimed to identify putative functional pol...
