Sandfly fever group viruses in the genus Phlebovirus (family Bunyaviridae) are widely distributed across the globe and are a cause of disease in military troops and indigenous peoples. We assessed the laboratory sensitivity and specificity of the Sand Fly Fever Virus Antigen Assay, a rapid dipstick assay designed to detect sandfly fever Naples virus (SFNV) and Toscana virus (TOSV) against a pan...

Sandfly control measures were evaluated at the Da Barra Ranch, Lobato municipality, Paraná State, Brazil. The insects were captured with Falcão traps in houses, a cattle corral, and a forest area from July to November 1999 and from February to June 2000. In December 1999 and January 2000 the following measures were taken to decrease the sandfly density in peridomiciliary areas and domiciles: (i...

Species of Leishmania Ross, 190349, are exclusively parasitic protozoa of the Order Kinetoplastida, Family Trypanosomatídae. They are digenetic (heteroxenous) organisms, with promastigotes and paramastigotes (with a single, free flagellum) in the alimentary tract of the insect host, and round-oval amastigotes (no free flagellum) in the macrophages of vertebrate hosts: as far as is known there i...

Phlebotomine sandflies are vectors of phleboviruses that cause sandfly fever or meningitis with significant implications for public health. Although several strains of these viruses had been isolated in Iran in the late 1970's, there was no recent data about the present situation at the outset of this study. Entomological investigations performed in 2009 and 2011 in Iran collected 4,770 sandfli...

Leishmania are digenetic protozoa which inhabit two hosts, the sandfly where they grow as promastigotes in the gut, and the mammalian macrophage where they grow as amastigotes. Sandfly (or sand fly) is a colloquial name for any species or genus of flying, biting, blood-sucking Dipteran encountered in sandy areas. In the United States, sandfly may refer to certain horse flies that are also known...

Sandflies are widely distributed around the Mediterranean Basin. Therefore, human populations in this area are potentially exposed to sandfly-transmitted diseases, including those caused by phleboviruses. Whilst there are substantial data in countries located in the northern part of the Mediterranean basin, few data are available for North Africa. In this study, a total of 1489 sandflies were c...

Sandfly fever viruses (SFV) are endemic in the Mediterranean, Middle East, northern African and western Asian countries. Toscana virus (TOSV), serotype of Sandfly fever Naples virus, is among of the three most prevalent viruses associated with meningitis during the warm seasons in northern Mediterranean countries. The historical data of the sandfly fever (Pappataci fever) indicates its origin i...

Leishmania parasites expose phosphatidylserine (PS) on their surface, a process that has been associated with regulation of host's immune responses. In this study we demonstrate that PS exposure by metacyclic promastigotes of Leishmania amazonensis favours blood coagulation. L. amazonensis accelerates in vitro coagulation of human plasma. In addition, L. amazonensis supports the assembly of the...
