Will Mayaro virus be responsible for the next outbreak of an arthropod-borne virus in Brazil?

Brazilian Journal of Infectious Diseases, 2017
Mayaro virus is an alphavirus from the Togaviridae family and is transmitted mainly by Hemagogus mosquitoes. This virus circulates in high-density tropical forests or rural areas of Central and South America causing a disease characterized by high-grade ...

Oxidative stress in Mayaro virus infection

Virus Research, 2017
Mayaro virus (MAYV) is a neglected tropical arbovirus that causes a febrile syndrome that is sometimes accompanied by incapacitating arthritis/arthralgia. The pathogenesis of MAYV has not been completely defined and oxidative stress mediated by an increase in reactive oxygen species (ROS) and/or depletion of antioxidant defences has been found to ...

A comprehensive murine clinical model for development of countermeasures and studying Mayaro virus infection. [PDF]

PLoS Negl Trop Dis
The Mayaro virus (MAYV) is an arthropod-borne virus that causes Mayaro fever, a neglected tropical disease that produces disabling arthralgia. Given the significant threat the dissemination of MAYV poses to global public health, the development of animal

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,

Evolutionary Profile of Mayaro Virus in the Americas: An Update into Genome Variability. [PDF]

Viruses
The Mayaro virus (MAYV) is an arbovirus with emerging potential, though with a limited understanding of its epidemiology and evolution due to the lack of studies and surveillance. Here, we investigated 71 MAYV genome sequences from the Americas available

Molecular Epidemiology of Mayaro Virus among Febrile Patients, Roraima State, Brazil, 2018-2021. [PDF]

Emerg Infect Dis
We detected Mayaro virus (MAYV) in 3.4% (28/822) of febrile patients tested during 2018–2021 from Roraima State, Brazil. We also isolated MAYV strains and confirmed that these cases were caused by genotype D.

Immunogenic recombinant Mayaro virus-like particles present natively assembled glycoprotein. [PDF]

NPJ Vaccines
Virus-like particles (VLPs) are an established vaccine platform and can be strong immunogens capable of eliciting both humoral and cellular immune responses against a range of pathogens. Here, we show by cryo-electron microscopy that VLPs of Mayaro virus,
