The Mayaro virus and its potential epidemiological consequences in Colombia: an exploratory biomathematics analysis

Parasites & Vectors, 2020
Background Mayaro virus (Togaviridae) is an endemic arbovirus of the Americas with epidemiological similarities with the agents of other more prominent diseases such as dengue (Flaviviridae), Zika (Flaviviridae), and chikungunya (Togaviridae).

Cryo-EM structure of the mature and infective Mayaro virus at 4.4 Å resolution reveals features of arthritogenic alphaviruses

Nature Communications, 2021
Mayaro virus (MAYV) is an emerging arbovirus in Central and South America that is transmitted by mosquitoes and causes arthritogenic disease. Here, the authors present the 4.4 Å resolution cryo-EM structure of MAYV and describe specific features of the ...

The genetic structure of Aedes aegypti populations is driven by boat traffic in the Peruvian Amazon. [PDF]

, 2019
In the Americas, as in much of the rest of the world, the dengue virus vector Aedes aegypti is found in close association with human habitations, often leading to high population densities of mosquitoes in urban settings.

Identification of Mayaro Virus Genotype D in Rondônia, Brazil. [PDF]

Am J Trop Med Hyg
ABSTRACT. The Mayaro virus (MAYV) is a significant reemerging arbovirus of public health concern, responsible for outbreaks in several countries including Brazil. In this study, 857 samples of patients with acute fever in the state of Rondônia, Brazil, were analyzed by reverse transcriptase qualitative polymerase chain reaction (RT-qPCR) to detect Zika,

Oropouche virus: clinical, epidemiological, and molecular aspects of a neglected orthobunyavirus. [PDF]

, 2017
Oropouche virus (OROV) is an important cause of arboviral illness in Latin American countries, more specifically in the Amazon region of Brazil, Venezuela and Peru, as well as in other countries such as Panama.

Virucidal activity of proanthocyanidin against Mayaro virus

Antiviral Research, 2019
Mayaro virus (MAYV) is a sublethal arbovirus transmitted by mosquitoes with possible installation of an urban cycle in the Americas. Its infection causes disabling arthralgia, and still, there is no vaccine or treatment to it. We recently investigated nearly 600 compounds by molecular docking and identified epicatechin as a potent antiviral against ...

Experimental Transmission of Mayaro Virus by Aedes aegypti [PDF]

The American Society of Tropical Medicine and Hygiene, 2011
Outbreaks of Mayaro fever have been associated with a sylvatic cycle of Mayaro virus (MAYV) transmission in South America. To evaluate the potential for a common urban mosquito to transmit MAYV, laboratory vector competence studies were performed with Aedes aegypti from Iquitos, Peru. Oral infection in Ae.

Adaptive changes in alphavirus mRNA translation allowed colonization of vertebrate hosts [PDF]

, 2012
Members of the Alphavirus genus are arboviruses that alternate replication in mosquitoes and vertebrate hosts. In vertebrate cells, the alphavirus resists the activation of antiviral RNA-activated protein kinase (PKR) by the presence of a prominent RNA

What are the vector species of the Oropouche virus?

Pest Management Science, EarlyView.
Here, we review the timeline of Oropouche virus (OROV) detection in various hematophagous Diptera, from 1955 to date, including mosquitoes and midges. All vector competence experiments also are described. The results suggest that Culicoides are the primary vectors.
