Phlebotomine sandflies are the vectors for the protozoan parasites that cause leishmaniasis. The present study investigated the species composition of sandfly fauna in the rural district of Taquaruçú, municipality of Palmas, state of Tocantins, Brazil and compared the diversity of species among intradomicile, peridomicile and forest environments during the dry and rainy seasons. Sandflies were ...
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...
Grapevine fanleaf virus (GFLV) is one of the main causes grapevine degeneration disease (GFDD) and present in almost all areas where cultivated. In this work, we ascertained presence spread GFLV different commercial vineyards four Sicilian provinces (Italy), its genetic structure molecular variability were studied. detail, a total 617 samples 11 autochthonous cultivars collected 20 vineyards. P...
Military personnel are at high risk of contracting vector-borne and zoonotic infections, particularly during overseas deployments, when they may be exposed to endemic or emerging infections not prevalent in their native countries. We conducted seroprevalence testing of 467 UK military personnel deployed to Helmand Province, Afghanistan, during 2008-2011 and found that up to 3.1% showed seroconv...
The possible effect of virus adaptation to different transmission routes on virus stability in the environment is not well known. In this study we have compared the stabilities of three viruses within the Bunyaviridae family: the rodent-borne Hantavirus Hantaan virus (HTNV), the sand fly-borne Phlebovirus sandfly fever Sicilian virus (SFSV), and the tick-borne Nairovirus Crimean-Congo hemorrhag...
Toscana virus (TOSV), which is transmitted by Phlebotomus spp. sandflies, is a major etiologic agent of aseptic meningitis and encephalitis in the Mediterranean. Like other members of the genus Phlebovirus of the family Bunyaviridae, TOSV encodes a nonstructural protein (NSs) in its small RNA segment. Although the NSs of Rift Valley fever virus (RVFV) has been identified as an important virulen...
The use of renewable energy sources is one of the most relevant goals to be achieved in order to match the climate protection targets. As a case study, the paper shows the current electrical energy production by sources in the Sicilian context. Among the renewable energy sources, the paper investigates the wave energy potential along the Sicilian coasts, because of the favorable climate around ...
The relative in vitro antiviral activities of three related nucleoside carboxamides, ribavirin (1-beta-D-ribofuranosyl-1,2,4-triazole-3-carboxamide), tiazofurin (2-beta-D-ribofuranosylthiazole-4-carboxamide), and selenazole (2-beta-D-ribofuranosylselenazole-4-carboxamide), were studied against selected DNA and RNA viruses. Although the activity of selenazole against different viruses varied, it...
