Study of Arboviruses in Philander opossum, Didelphis marsupialis and Nectomys r...

Bernal,Marcella Katheryne Marques; Chiang,Jannifer Oliveira; Mendes,Fernanda Figueiredo; Andrade,Sara Letícia dos Santos

ABSTRACT: Arboviruses are viruses that maintain their life cycle in the wild and are transmitted to vertebrate hosts by hematophagous diptera. They are zoonotic and can establish an enzootic cycle in the urban areas; in humans, the infection can manifest from being encephalitogenic to hemorrhagic. This study aimed to report the occurrence of arboviruses in mammals of the order Didelphimorphia and Rodentia, capt...

ABSTRACT: The State of Pará comprises 26% of Brazilian Amazon region, where a large diversity of arboviruses has been described. This study sought to assess the prevalence and distribution of hemagglutination inhibition (HI) antibodies against antigens of four alphaviruses (Togaviridae: Alphavirus ) from the species: Eastern equine encephalitis (EEEV), Western equine encephalitis (WEEV), Mayaro virus (MAYV), an...

Introduction A sero-epidemiological survey was undertaken to detect the circulation of arboviruses in free-living non-human primates. Methods Blood samples were obtained from 16 non-human primates (13 Sapajus spp. and three Alouatta caraya) that were captured using terrestrial traps and anesthetic darts in woodland regions in the municipalities of Campo Grande, Aquidauana, Jardim, Miranda and Corumbá in the Sta...

Cruz,Ana Cecilia Ribeiro; Prazeres,Assis do Socorro Correa dos; Gama,Eliana Colares; Lima,Maxwell Furtado de; Azevedo,Raimunda do Socorro Silva

O objetivo foi avaliar a prevalência de anticorpos para arbovírus na área de influência do Projeto Juruti antes da exploração mineral local. Foram examinados 1.597 soros humanos e 85 de animais silvestres. A pesquisa de anticorpos foi realizada pelo teste de inibição da hemaglutinação contra antígenos dos arbovírus mais prevalentes na Amazônia brasileira e IgM-ELISA para dengue e febre amarela. Soros humanos in...

The Acre Project: the epidemiology of malaria and arthropod-borne virus infecti...

Silva-Nunes,Mônica da; Malafronte,Rosely dos Santos; Luz,Bruna de Almeida; Souza,Estéfano Alves de; Martins,Lívia Carício; Rodrigues,Sueli Guerreiro

The authors describe the baseline malaria prevalence and arbovirus seroprevalence among 467 subjects in an ongoing cohort study in rural Amazonia. Most subjects (72.2%) reported one or more previous episodes of malaria, and 15.6% had been hospitalized for malaria, but only 3.6% of individuals five years or older had malaria parasites detected by microscopy (10 with Plasmodium vivax and 4 with P. falciparum). An...
