Epidemiologic Relationship between Toscana Virus Infection and Leishmania infantum Due to Common Exposure to Phlebotomus perniciosus Sandfly Vector
Sand flies are recognised vectors of parasites in the genus Leishmania and a number of arthropod-borne viruses, in particular viruses within the genus Phlebovirus, family Bunyaviridae. In southern France, Toscana phlebovirus (TOSV) is recognized as a prominent cause of summer meningitis. Since Leishmania and TOSV have a common vector (Phlebotomus perniciosus), an epidemiologic link has been ass...
متن کاملPhlebotomus sergenti a common vector of Leishmania tropica and Toscana virus in Morocco.
BACKGROUND & OBJECTIVES An entomological study using CDC miniature light-traps was performed in El Hanchane locality, where cutaneous leishmaniasis (CL) was emerging during the summer of 2011. The aim of this study is to identify the vectors of Leishmania and of phleboviruses. METHODS In the field, a total of 643 sandfly specimens were collected, identified by morphological keys and categoriz...
متن کاملExperimental infection of Phlebotomus perniciosus by bioluminescent Leishmania infantum using murine model and artificial feeder
Leishmaniasis is a vector-borne disease that is transmitted by sandflies and caused by obligate intracellular protozoa of the genus Leishmania. In the present study, we carried out a screening on the experimental infection of Phlebotomus pernioucus by bioluminescent Leishmania infantum using murine model and artificial feeder. We developed a real-time polymerase chain reaction (RT-PCR)-based me...
متن کاملEncephalitis without meningitis due to sandfly fever virus serotype toscana.
The role of Toscana (TOS) virus in producing encephalitis without meningitis is uncertain. We studied 2 cases of TOS virus encephalitis without meningitis by means of nested polymerase chain reaction assay and DNA sequencing. Findings confirm that TOS virus may directly cause encephalitis and suggest the usefulness of DNA sequencing in investigating relationships between TOS virus molecular pat...
متن کاملInfections due to sandfly fever virus serotype Toscana in Spain.
Of the sandfly fever viruses known to be human pathogens (serotypes Toscana [TOS], Sicilian [SFS], and Naples [SFN]), only TOS has demonstrated neurotropic activity. Infections by TOS have been reported in Mediterranean countries, but the virus was previously isolated only in Italy and Portugal. We isolated 15 strains of TOS between 1988 and 1996 from the cerebrospinal fluid of patients with ac...
