Invasive Mosquito

Literature on distribution of invasive mosquito species that are vectors of especially dangerous infections (dengue, Chikungunya, Zika, yellow fever, and Japanese encephalitis) in the Europe and Russia was briefly reviewed. Global warming of the climate as well as an increase in the volume of world trade and the biological characteristics of mosquitoes contribute to the widespread of these species on territories of many countries and continents

The family Flaviviridae currently consists of four recognized genera: Flavivirus, Pestivirus, Hepacivirus, and Pegivirus. Although members of the family have a large host range that includes both vertebrates and invertebrates, only members of the genus Flavivirus are known as arboviruses, vectored either by mosquitoes or ticks. The remaining genera in the family are exclusively found in mammals, and their diversity has greatly expanded with recent virus discoveries. The genus Flavivirus comprises 92 virus species, of which over 40 can cause human infection. Many of these include important human pathogens such as Zika, dengue, yellow fever, West Nile, and Japanese encephalitis virus.

Chimeric Viruses

ABSTRACT A system has been developed for generating chimeric yellow fever/Japanese encephalitis (YF/JE) viruses from cDNA templates encoding the structural proteins prM and E of JE virus within the backbone of a molecular clone of the YF17D strain. Chimeric viruses incorporating the proteins of two JE strains, SA14-14-2 (human vaccine strain) and JE Nakayama (JE-N [virulent mouse brain-passaged strain]), were studied in cell culture and laboratory mice. The JE envelope protein (E) retained antigenic and biological properties when expressed with its prM protein together with the YF capsid; however, viable chimeric viruses incorporating the entire JE structural region (C-prM-E) could not be obtained. YF/JE(prM-E) chimeric viruses grew efficiently in cells of vertebrate or mosquito origin compared to the parental viruses. The YF/JE SA14-14-2 virus was unable to kill young adult mice by intracerebral challenge, even at doses of 106 PFU. In contrast, the YF/JE-N virus was neurovirulent, but the phenotype resembled parental YF virus rather than JE-N. Ten predicted amino acid differences distinguish the JE E proteins of the two chimeric viruses, therefore implicating one or more residues as virus-specific determinants of mouse neurovirulence in this chimeric system. This study indicates the feasibility of expressing protective antigens of JE virus in the context of a live, attenuated flavivirus vaccine strain (YF17D) and also establishes a genetic system for investigating the molecular basis for neurovirulence determinants encoded within the JE E protein.

Vector Borne

Arthropod-borne infections carried by mosquitoes and ticks are difficult to eradicate, once rooted, and have frequently caused wide-area epidemics such as dengue fever, West Nile fever, chikungunya fever, yellow fever, Japanese encephalitis and Rift Valley fever. Factors such as global warming and overpopulation have aggravated urban epidemics caused by dengue and chikungunya viruses. Measures against arthropods have their limitations, however, so nonepidemic areas must be protected against invasion by vector-borne diseases through quarantine, education and effective vaccination.
