Studies on overwintering of bluetongue viruses in insects.
Bluetongue viruses (BTVs) are economically important arboviruses that affect sheep and cattle. The overwintering mechanism of BTVs in temperate climates has eluded researchers for many years. Many arboviruses overwinter in their invertebrate vectors. To test the hypothesis that BTVs overwinter in their vertically infected insect vectors, Culicoides sonorensis larvae were collected from long-ter...
متن کاملSeasonal gene expression kinetics between diapause phases in Drosophila virilis group species and overwintering differences between diapausing and non-diapausing females
Most northern insect species experience a period of developmental arrest, diapause, which enables them to survive over the winter and postpone reproduction until favorable conditions. We studied the timing of reproductive diapause and its long-term effects on the cold tolerance of Drosophila montana, D. littoralis and D. ezoana females in seasonally varying environmental conditions. At the same...
متن کاملViral encephalitis caused by respiratory viruses
Results Using molecular diagnostic methods (PLEX-ID, Multiplex PCR) we identified, in the respiratory secretions and in the CSF: H1N1 influenza virus (2009), influenza AH3 virus, influenza B virus, coronavirus and adenovirus. The most severe forms of the disease were caused by the influenza virus H1N1. There were 2 cases of encephalitis admitted with this etiology, one of which had a fatal outc...

متن کاملLaboratory transmission of Japanese encephalitis and West Nile viruses by molestus form of Culex pipiens (Diptera: Culicidae) collected in Uzbekistan in 2004.
We evaluated the molestus form of Culex pipiens pipiens (L.) (hereafter referred to as "molestus") captured near Tashkent, Uzbekistan, for their ability to transmit Japanese encephalitis (family Flaviviridae, genus Flavivirus, JEV) and West Nile (family Flaviviridae, genus Flavivirus, WNV) viruses under laboratory conditions. These molestus were highly competent laboratory vectors of WNV, with ...
