Abstract:
Visceral leishmaniasis is a systemic infectious disease that can cause to a severe, potentially life-threatening chronic condition in humans. Risk factors for infection in urban areas have been associated with poor living conditions, the presence of sand fly vectors and infected pets. This study aimed to describe sand fly and canine infection in the neighborhoods of human visceral leishmaniasis occurrence in the city of Cuiabá, Mato Grosso State, central-western Brazil, reported between January 2005 and December 2006. A total of 1,909 sand flies were collected. They were predominantly males an

Background Several new species of Leishmania have recently emerged in Europe, probably as the result of global changes and increased human migration from endemic areas. In this study, we tested whether two sand fly species, the Western Mediterranean Phlebotomus perniciosus and the Eastern Mediterranean P. tobbi, are competent vectors of L. donovani, L. major and L. martiniquensis.

ABSTRACT A seminested PCR assay was developed in order to amplify the kinetoplast minicircle of Leishmania species from individual sand flies. The kinetoplast minicircle is an ideal target because it is present in 10,000 copies per cell and its sequence is known for most Leishmania species. The two-step PCR is carried out in a single tube using three primers, which were designed within the conserved area of the minicircle and contain conserved sequence blocks. The assay was able to detect as few as 3 parasites per individual sand fly and to amplify minicircle DNA from at least eightLeishmania

Abstract:
Toscana virus (TOSV) is an emerging but neglected human pathogen currently circulating around the Mediterranean basin including North Africa. Human illness ranges from asymptomatic or mild flu-like syndromes to severe neurological diseases such as meningitis or meningoencephalitis. Despite its significant impact, understanding of TOSV transmission and epidemiology remains limited. Sand flies (Diptera: Phlebotominae), specifically Phlebotomus perniciosus and Phlebotomus perfiliewi, are believed to be the primary vectors of TOSV. However, the spread of TOSV to new geographical areas and its dete

Abstract:
Multiple strategies involving the parasite-host-vector triad are necessary to control leishmaniasis. One option is to prevent or reduce transmission of the pathogen by the phlebotomine sand fly vectors. In this sense, it is essential to explore compounds that may influence the vectorial capacity of the insect and reduce its longevity. We investigated the effect of anti-Leishmania drugs administered via the sugar meal on longevity, blood feeding, oviposition, and parasite load on the third day of infection of the sand flies, to identify the most promising candidates for vector infection tests.

The Leishmania spp. are kinetoplastid protozoan parasites that cause a spectrum of highly prevalent and neglected tropical diseases known as leishmaniasis. The parasites must undergo two life forms during their life cycle: the extracellular promastigote life stage within the sand fly vector, and the intracellular amastigote life stage after internalization of host phagocytic cells. In the extracellular life stage, Leishmania promastigotes reside and develop to their infectious metacyclic form solely in the gut lumen of the sand fly, a process known as metacyclogenesis.

Transmitted by sand fly vectors, Leishmania parasites preferentially infect host macrophages throughout the viscera. Experimental L. donovani infection in genetically susceptible mice elicits a highly organ-specific outcome that mirrors much of the immunopathology observed in human VL patients.

A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. Worms or helminths either live as parasites or free of a host in aquatic and terrestrial environments. Parasites and worms are found worldwide but mainly in the tropics. It is estimated that 20% of immigrants from endemic countries may have helminthic infections at their arrival to the UK. These people could be asymptomatic, but tend to present with unexplained symptoms, especially gastrointestinal in nature or eosinophilia.

Although diagnostic techniques and clinical symptoms can establish illness status, it is extremely difficult to diagnose infection in the absence of symptoms.
