Conclusion: Mosquitoes and midges have got a crucial role in the transmission of arboviruses. The risk of occurrence for the investigated arboviruses will continue depending upon many factors including the presence of these viruses in Turkey and its neighboring countries, uncontrolled livestock movements, global warming and climate changes.

Conclusions: Two large areas were found as the ecological niches of larvae of these species. It is recommended that additional investigations be carried out on infection in adult female Cx. pipiens and its hosts in these areas. PMID: 31745415 [PubMed]

West Nile virus (WNV) is a neurotropic flavivirus and the leading cause of mosquito-borne diseases in North America. In approximately 20% of cases, infection leads to a self-limited febrile illness and, in less than 1%, to a neuroinvasive disease often manifesting as meningoencephalitis with or without acute flaccid paralysis.1 Herein, we report the first case of WNV-associated CNS vasculitis and intracranial hemorrhage, thus expanding the spectrum of WNV infection.

Uhrlaub, William H. Hildebrand, Janko Nikolich-Žugich, Cornelia M. Weyand, Jörg J. GoronzySummaryGeneration of protective immunity to infections and vaccinations declines with age. Studies in healthy individuals have implicated reduced miR-181a expression in T cells as contributing to this defect. To understand the impact of miR-181a expression on antiviral responses, we examined LCMV infection in mice with miR-181ab1-deficient T&nbs...

We present evidence that these observations are only partly explained by differences in nucleotide composition of the complete viral codon regions. We consider the combination of nucleotide composition, amino acid composition, and codon usage preference suitable to provide information on possible evolutionary similarities between distant virus species that cannot be investigated by phylogeny.

Abstract Culex mosquitoes are vectors of several flaviviruses and alphaviruses posing a potential risk to public and veterinary health. In order to gain an insight into the flaviviruses and alphaviruses circulating in the five regional units of Central Macedonia in northern Greece, 17,470 female Culex spp. mosquitoes collected during 2018 were tested for these viruses. Among 229 mosquito pools, West Nile virus (WNV) was detected in 10 (4.4%) pools, while insect-specific flavi- and alphaviruses were detected in 2 (0.9%) and 8 (3.5%) pools, respectively. WNV minimum infection rate (MIR) was 0.57. The highest MIR was...

Abstract Interferon-inducible transmembrane proteins (IFITMs) restrict infection by several viruses, such as influenza A virus, West Nile virus and dengue virus. It has not been determined whether porcine IFITM (pIFITM) inhibits infection by pseudorabies virus (PRV), an enveloped, double-stranded DNA virus, which is the etiological agent of Aujeszky's disease in pigs. Here, we report that PRV infection elicited pIFITM1 expression in PK15 porcine kidney epithelial cells and 3D4/21 alveolar macrophages. pIFITM2 and pIFITM3 expression was only elevated in PK15 cells during PRV infection. Depletion of pIFITM1 using RN...

Chow, Shirley Luckhart, Alan G. GoodmanSummaryThe World Health Organization estimates that more than half of the world’s population is at risk for vector-borne diseases, including arboviruses. Because many arboviruses are mosquito borne, investigation of the insect immune response will help identify targets to reduce the spread of arboviruses. Here, we use a genetic screening approach to identify an insulin-like receptor as a...
