Introdução: Arbovírus são causadores de doenças humanas, sendo que mudança ecológicas e aumento do contato humano-vetor aumenta a possibilidade de surtos. Objetivo: Detectar, identificar e caracterizar arbovírus presentes em mosquitos vetores capturados em regiões de mata próximas a Três Lagoa...

Chikungunya virus is an alphavirus, member of the Togaviridae family, first discovered in Africa in 1952. Since then it caused sporadic outbreaks in Africa and Asia, but since 2000, outbreaks had been more frequent, being identified in Europe, America and the Caribbean. Chikungunya virus can cause chr...
Abstract INTRODUCTION: The Mayaro virus (MAYV), which is an arbovirus closely related to the Chikungunya virus, causes a dengue-like acute illness that is endemic to Central and South America. We investigated the anti-MAYV activity of prostaglandin A1 (PGA1), a hormone which exhibits antiviral activity...

Abstract 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 fever, maculopapular skin rash and marked ...
ABSTRACT Arboviruses pose a serious threat to public health worldwide, overloading the healthcare system and causing economic losses. These viruses form a very diverse group, and in Brazil, arboviruses belonging to the families Flaviviridae and Togaviridae are predominant. Unfortunately, the number of ar...

Abstract Arboviruses impose a serious threat to public health services. We report a case of a patient returning from a work trip to the Amazon basin with myalgia, arthralgia, fever, and headache. During this travel, the patient visited riverside communities. Both dengue and Chikungunya fevers were first ...
BACKGROUND: New sequencing technologies have opened the way to the discovery and the characterization of pathogenic viruses in clinical samples. However, the use of these new methods can require an amplification of viral RNA prior to the sequencing. Among all the available methods, the procedure based on...
