Usutu Virus: An Emerging Arbovirus Threat
Mosquito-borne viruses, such as dengue virus (DENV), Zika virus (ZIKV), chikungunya virus (CHIKV), yellow fever virus (YFV), Japanese encephalitis virus (JEV), and West Nile virus (WNV) are major threats to global public health resulting in millions of infections and hundreds of thousands of deaths …

Mosquito Species Abundance, Diversity and Arbovirus Prevalence across Different Land-use in The Gambia
Mosquito-borne arboviruses represent an escalating public health threat across sub-Saharan Africa, yet surveillance remains limited in many countries, including The Gambia. This study investigates mosquito species abundance and diversity, as well as the arbovirus prevalence across human, …

The Effect of Precipitation on the Spread of Mosquito-Borne Diseases: A Case Study of Florida Counties
… estimate, as well as, the data on six (6) arboviruses, over the course of thirteen (13) years, namely 2002 to 2014. The first hypothesis that was tested, was that greater precipitation increased the likelihood of a greater number of arbovirus cases. It was important to also examine the …

The role of mosquito saliva on host immune response and pathogenesis of West Nile virus\r\n
… course. In the past most small animal models of arbovirus disease have used needle-inoculation, but recent evidence suggests that because of the potential effects of mosquito saliva on the immune system, it is important to re-evaluate the pathogenesis of these infections in the presence of …

Evidence for RNA interference as an antiviral immune response to alphavirus infection in the mosquitoes Anopheles gambiae and Aedes aegypti
… to the development of new strategies to control arbovirus transmission. First, potential genes in the mosquito RNAi pathway were identified in the Anopheles gambiae genome. Genes in the dicer and argonaute gene families were tested for their involvement in the RNAi pathway in An. gambiae cells …

Using Altered Fidelity Viruses to Study Viral Attenuation and Population Genetics During Vertebrate Host Infection
… vertebrate hosts for the host life cycle of an arbovirus constrains its evolution. For the viral population to survive in two hosts, the ability to produce genetic diversity within the population is essential. RNA viruses contain an RNA dependent RNA polymerase (RdRp) that creates a population …

Anti-Insect Defensive Behaviors of Equines after West Nile Virus Infection
West Nile Virus is an important arbovirus (virus transmitted by arthropods) that has recently affected the health of both humans and animals in the United States. West Nile fever was first identified in the US in 1999. West Nile virus (WNV), vectored by mosquitoes, has had a detrimental impact on …

Battle of the Viruses: Aripo Virus Induced Superinfection Exclusion of Mosquito-borne Viruses
… in opportunities to discover a novel approach to arbovirus control. The exclusionary effects of ARPV were explored as a means to eventually understanding superinfection exclusion (SIE) and utilizing it as a calculated defense against mosquito-borne disease. Aripo virus was evaluated for its SIE …

Infection and Dissemination of TaV-GFP Tagged Sindbis in Aedine Mosquitoes and Cell Lines
Arthropod-borne-viruses (arboviruses) pose a global threat due to their ability to be transmitted by hematophagous insects to vertebrate hosts resulting in a range of serious infectious diseases. Sindbis virus (SINV) is the prototype arbovirus of the genus Alphavirus in the family Togaviridae. The …

Factores asociados con la presencia de dengue grave en pacientes colombianos con diagnóstico confirmado de dengue 2013-2015
Introducción: El dengue es el arbovirus más importante del mundo. Colombia es hiperendémico por esta enfermedad y su complicación severa está presente en la población colombiana. Objetivo: Determinar los factores sociodemográficos, clínicos y de laboratorio que se asocian con la presencia de dengue …

The Role of Long Distance Movement and Genetic Adaptation on the Evolution of West Nile virus in the New World
West Nile virus (WNV) is an emerging arbovirus that is maintained in an epizooitic cycle involving birds and mosquitoes. After a long history of circulation in the Old World, WNV was introduced into the US and identified in the New York Metropolitan Area during the summer of 1999. While the initial …

Freirean Codes: A Transformative Educational Tool for Community Empowerment and Arboviral Control in Kenya
… areas should be implemented. The knowledge of arbovirus infections is limited. There is a lack of awareness about proper source reduction and mosquito life cycle; perceived importance of covering drinking water and keeping it free from insects but not water used for other purposes. Also, a huge …

Blood-Feeding Patterns of Eastern Equine Encephalitis Virus Bridge Vectors at Viral Foci in Southeast Georgia
… virus (EEEV) is a single-stranded RNA arbovirus (family <em>Togaviridae; </em>genus <em>Alphavirus) </em>endemic to the Atlantic seaboard, southeastern United States, and parts of South America. EEEV produces particularly severe disease in incidental (dead-end) hosts such as humans and …

Linking mosquito midgut and virus population biology at the molecular and cellular level
… These findings have important implications for arbovirus emergence and evolution. The mosquito midgut functions as a key interface between virus and vector. However, studies of midgut physiology and associated virus infection dynamics are scarce, and in Culex tarsalis - the primary vector of …

Characterization of genetic reassortment and recombination potentials between Arumowot Virus and MP-12 vaccine strain
Rift Valley fever virus (RVFV) is a zoonotic arbovirus that causes significant morbidity and mortality in both humans and animals. In humans, the disease manifests itself as febrile illness, hemorrhagic fever, encephalitis, or retinitis. In animals, RVFV causes high rates of abortions and fetal …
