We report the 1st collection of Phlebotomus sergenti, a vector of the cutaneous and visceralizing forms of Leishmania tropica, from southern Egypt. Four female and 1 male P. sergenti were collected from unlit Centers for Disease Control light traps placed in a village on the Nile River, 6 km north of Aswan, Egypt, during studies conducted from 1998 to 1999. This extends the known distribution o...

BACKGROUND The saliva of sand flies strongly enhances the infectivity of Leishmania in mice. Additionally, pre-exposure to saliva can protect mice from disease progression probably through the induction of a cellular immune response. METHODOLOGY/PRINCIPAL FINDINGS We analysed the cellular immune response against the saliva of Phlebotomus papatasi in humans and defined the phenotypic character...

An entomological investigation performed in 2013 covering different bio-geographical areas varying from humid in the north to the arid in the center showed that sand flies of the subgenus Larroussius including Phlebotomus perniciosus, Phlebotomus perfiliewi, and Phlebotomus longicuspis are abundant and widely distributed in Tunisia. A total of 3992 collected and pooled with up to 30 specimens p...

To editor: Toscana Virus belongs to the genus Phleobovirus, family Bunyaviridae. They are transmitted in the Mediterranean area by Phlebotomus perniciosus and Phlebotomus perfiliewi sandflies (Braito et al., 1997). Toscana virus (TOSV) was first isolated in 1971 from Phlebotomus perniciosus in Monte Argentario (Grosseto, Tuscany) (Verani et al., 1982). Sandflyborne TOSV was recognized as a lead...

During summer 2007, a total of 785 phlebotomine flies were trapped in northern Algeria, identified morphologically, organised as monospecific pools and tested for the presence of phlebovirus RNA using degenerate primers. Three pools were positive, and the corresponding PCR products were cloned and sequenced. Viral sequences corresponding to two phleboviruses distinct from each other were detect...

In this talk we discuss the possible closures of geodesic planes in a hyperbolic 3-manifold M. When M has finite volume Shah and Ratner (independently) showed that a very strong rigidity phenomenon holds, and in particular such closures are always properly immersed submanifolds of M with finite area. Manifolds with infinite volume, however, are far less understood and are the main subject of th...

The joint source channel coding problem of transmitting a pair of correlated sources over a 2−user MAC is considered. A new concatenated coding scheme, comprising of an inner code of fixed block-length and an outer code of arbitrarily large block-length, is proposed. Its information theoretic performance is analyzed to derive a new set of sufficient conditions. An example is identified to demon...

during the period of april to november 1994, an investigation was carried out on fauna of phlebotominac in ilam province, west of iran. about 12000 sandflies were caught by sticky trap, light trap and aspirator from different ecological regions and were identified. these sandflies consist of 22 species (11 species from the genus phlebotomus: ph. paptasi, ph.sergenti, ph.alexandri, ph.rnajor, ph...

An entomological survey was carried out in two districts of central (Kruje) and northern (Lezhe) Albania. Six collecting sites, showing a variety of diurnal resting sites, were monitored for adult sandflies from June through October 2002. Flies were collected with CDC miniature light traps, sticky traps and mechanical or hand aspirators in peridomestic sites, in bedrooms and inside cow barns, c...
