Arboviruses are viruses transmitted to humans and/or animals by hematophagous arthropods. They have a significant economic and public health impact. Given the number of arboviruses already identified their great genetic variability, it is essential highly flexible tools for monitoring. Arbovirus circulation within animal populations can be demonstrated direct indirect screening specific virus v...

The arboviruses have a worldwide distribution and, mosquitoes and ticks contribute principally in their transmission. In the last two decades, arboviral diseases have been recognised due to their resurgence and spread in newer geographic areas. Surveys to determine the prevalence of arboviruses in any region largely depend on the isolation attempts from the arthropods along with the serosurveys...

Arbovirus control depends on accurate projections of likely changes in the arthropod vector species, essential to inform local and global public health authorities. According WHO Assembly Global Vector Control Response (GVCR), by 2030, burden vector-borne diseases, particularly arbovirus infections, is expected be greatly decreased. However, anthropogenic drivers, including climate change, inse...

Pará State comprises 26% of Brazilian Amazon Region where a large diversity of arboviruses has been described. This study aimed to assess the prevalence and distribution of hemagglutination-inhibition (HI) that detect antibodies against four units to Eastern equine encephalitis virus (EEEV), Western equine encephalitis virus (WEEV), Mayaro virus (MAYV) and Mucambo virus (MUCV), a subtype of the...

Arboviruses are transmitted to vertebrate hosts by biting arthropod vectors such as mosquitoes, ticks, and midges. These viruses replicate in both arthropods and vertebrates and are thus exposed to different antiviral responses in these organisms. RNA interference (RNAi) is a sequence-specific RNA degradation mechanism that has been shown to play a major role in the antiviral response against a...

Here, we present the genome sequences of one mesonivirus and four novel arboviruses observed in Culex bitaeniorhynchus and Culex pipiens, captured in and near the demilitarized zone, Republic of Korea. Results suggest the ubiquitous presence of mesoniviruses and the discovery of a potentially new species of arboviruses in field-captured mosquitoes.

Arthropod-borne viruses, or arboviruses, are viruses that are transmitted through the bites of mosquitoes and ticks. There are numerous arboviruses throughout the world capable of causing human disease spanning different viral families and genera. Recently, dengue, chikungunya, and zika viruses have emerged as increasingly important arboviruses that can cause human disease, however no specific ...

The Australian Government is currently promoting the development of Northern Australia, with an associated increase in the local population. Consequent to this is the public health threat posed by heightened human exposure to many previously neglected arboviruses that are indigenous to the region. This initiative to support economic activity in the tropical north of the continent is leading to ...

Immune and non-immune rubella sera were examined in the haemagglutination inhibition (HAI) test to evaluate the removal of lipoprotein non-specific inhibitors (NSI) of haemagglutination after kaolin and manganous chloride/heparin treatments. The sera were titrated fresh or after lipoprotein deterioration brought about by ageing the samples at 4 degrees C for various periods of time and by freez...

As in humans, sub-clinical infection by arboviruses in domestic animals is common; however, its detection only occurs during epizootics and the silent circulation of some arboviruses may remain undetected. The objective of the present paper was to assess the current circulation of arboviruses in the Nhecolândia sub-region of South Pantanal, Brazil. Sera from a total of 135 horses, of which 75 w...
