INT J MOL SCI 26/12/20 Application of Aptamer-Based Assays to the Diagnosis of Arboviruses Important for Public Health in Brazil. Arbovirus infections represent a global public health problem, and recent epidemics of yellow fever, dengue, and Zika have shown their critical importance in Brazil and worldwide.

INT J MOL SCI 26/12/20 Application of Aptamer-Based Assays to the Diagnosis of Arboviruses Important for Public Health in Brazil

Whilst a major effort for vaccination programs has been in the spotlight, a number of aptamer approaches have been proposed in a complementary manner, offering the possibility of differential diagnosis between these arboviruses, which often present similar clinical symptoms, as well as the potential for a treatment option when no other alternative is available. In this review, we aim to provide a background on arbovirus, with a basic description of the main viral classes and the disease they cause, using the Brazilian context to build a comprehensive understanding of their role on a global scale. Subsequently, we offer an exhaustive revision of the diagnostic and therapeutic approaches offered by aptamers against arboviruses. ►▼ Show Figures Figure 1 ►▼ Show Figures Figure 1. Rev. Soc. Bras.

Résumé traduit : Ae. aegypti et Ae. albopictus a colonisé tous les types de microhabitats et de microenvironnements, principalement dans la zone urbanisée, de manière isolée et en coexistence. Le microhabitat d'Ae. aegypti a montré un gradient de température supérieur à celui d'Ae. albopictus, et il y avait une association avec les zones urbanisées pour les premières espèces et les zones boisées pour les dernières espèces. L'écologie du paysage et les différences intra-urbaines favorisent différents microclimats, qui contribuent à la coexistence d'espèces en milieu urbain dans une zone proche de la forêt, augmentant le risque d'autres infections à arbovirus en zone urbaine. La niche écologique doit être considérée pour Ae. albopictus. La surveillance entomologique et virologique est suggérée comme actions de surveillance des arbovirus dans les centres urbains infestés près des forêts préservées. – guatemalt

Acta Tropica Volume 202, February 2020, Ecological aspects of potential arbovirus vectors (Diptera: Culicidae) in an urban landscape of Southern Amazon, Brazil.

Résumé traduit : L'Amazonie a subi une pression humaine intense, en particulier dans ce que l'on appelle «l'Arc de déforestation» dans les régions de l'Est et du Sud. Les changements dans la biodiversité dus à la perturbation du paysage dans les municipalités de l'Arc de Déforestation sont susceptibles d'avoir un impact sur les espèces de moustiques conduisant au potentiel d'émergence d'arbovirus. Notre objectif était de décrire la composition et la structure des culicidés de Sinop, une municipalité située dans le sud de l'Amazonie dans l'État du Mato Grosso, ainsi que leur présence dans les habitats urbains, en analysant les variables climatiques et le risque potentiel de transmission des arbovirus. Une abondance, une richesse, une diversité et une équité plus élevées des espèces de moustiques ont été observées dans les parcs forestiers urbains et dans les nouveaux quartiers situés à la périphérie de la ville, à proximité de fragments de forêt et de zones agricoles. À mesure que l'environnement se consolide en milieu urbain, l'abondance et la richesse diminuent. Les quartiers fortement urbanisés dominaient davantage Culex quinquefasciatus, un moustique associé à différents arbovirus, notamment le virus de l'encéphalite du Nil occidental et de Saint Louis. L'espèce médicalement importante Cx. déclarant, Cx. (Melanoconion) ssp., Aedeomyia squamipennis et Aedes scapularis ont été trouvés dans les quatre habitats. Il est possible que ces moustiques s'adaptent à différents habitats et, par conséquent, qu'ils atteignent les zones urbanisées. L'abondance des moustiques était plus élevée les jours de températures élevées et de faibles précipitations dans les parcs forestiers urbains et dans les quartiers fortement urbanisés. Ces résultats suggèrent que la région de Sinop est un domaine clé pour la surveillance des vecteurs d'arbovirus. – guatemalt

Emerging mosquito-borne arboviral infections are widespread in the world, causing severe systemic and neurologic disorders that are virus- or immune-mediated1.

Dengue has been endemic in Rio de Janeiro City (RJC) since the 1980s. In January 2015, the Zika virus (ZIKV) was introduced in the city, followed by the chikungunya virus (CHIKV) in November of the same year2. Other countries were affected earlier and reported congenital syndrome related to the ZIKV and other neurologic conditions, mainly Guillain-Barré syndrome (GBS), due to the ZIKV and CHIKV3,4.

The first report on the increase in GBS occurrence originated from the French Polynesia in 2013, with a median time between acute ZIKV infection and neurologic signs and symptoms of 6 days, requiring supportive respiratory assistance in 1/3 of cases, not resulting in death4,5.

Abstract Viruses are important agents of emerging zoonoses and are a substantial public health issue.

PLOS 07/11/18 Lack of serological and molecular evidence of arbovirus infections in bats from Brazil

Among emerging viruses, an important group are arboviruses, which are characterized by being maintained in nature in cycles involving hematophagous arthropod vectors and a wide range of vertebrate hosts. Recently, bats have received increasing attention as an important source for the emergence of zoonoses and as possible viral reservoirs.

Among the arboviruses, there are many representatives of the genera Flavivirus and Alphavirus, which are responsible for important epidemics such as Dengue virus, Zika virus and Chikungunya virus. Due to the importance of analyzing potential viral reservoirs for zoonosis control and expanding our knowledge of bat viruses, this study aimed to investigate the presence of viruses of the Alphavirus and Flavivirus genera in bats.

Soc. Bras. Med. Trop. vol.49 no.6 Uberaba Nov./Dec. 2016 How are so many foreign arboviruses introduced in Brazil? To be maintained in nature, arboviruses (arthropod-borne-viruses) go through complex cycles involving vertebrate hosts and hematophagous vectors (mosquitoes, ticks, sandflies) that carry and transmit the virus to other organisms.

The host-vector conjunction, represented by two completely different animals, depends on the congruence of biology, geography, climate, ecology, and even economic factors. Although apparently improbable, this congruence of factors occurs, accounting for the existence of so many arboviruses, including some that produce human disease. More surprising is the rapid emergence of an arbovirus introduced in a new geographical area, after establishing new maintenance cycles based on the complex host-vector conjunction, as with some arboviruses introduced from distant global regions to the tropical Americas.
