The rapid and disorderly urbanization in the Amazon has resulted insertion of forest fragments into cities, causing circulation arboviruses, which can involve hematophagous arthropods free-ranging birds transmission cycles urban environments. This study aimed to evaluate arboviruses captured an Environmental Protection Area Belem metropolitan area, Brazil. Birds were using mist nets, collected a human protected attraction technique light traps. birds’ sera subjected hemagglutination...
The COVID-19 pandemic is the biggest public health threat facing world today. Multiple vaccines have been approved; however, emergence of viral variants such as recent Omicron raises possibility booster doses to achieve adequate protection. In Brazil, CoronaVac (Sinovac, Beijing, China) vaccine was used; it important assess immune response this over time. This study aimed monitor anti-SARS-CoV-2 antibody responses in those immunized with and SARS-CoV-2 infected individuals. Samples were...
Understanding the interaction between viruses and ecosystems in areas with or without anthropic interference can contribute to organization of public health services, as well prevention disease control. An arbovirus survey was conducted at Caxiuanã National Forest, Pará, Brazil, where 632 local residents, 338 vertebrates 15,774 pools hematophagous arthropods were investigated. Neutralization antibodies Venezuelan Equine Encephalitis virus, subtype IIIA, Mucambo virus (MUCV) detected 57.3%...
ABSTRACT: Arboviruses are agents transmitted by arthropods and represent a considerable threat to public health worldwide, causing diseases in humans animals. A serological investigation was carried out detect total antibodies against different types of arboviruses free-living coatis (Nasua nasua) from the Iguaçu National Park (INP) through Hemagglutination Inhibition test. Serum samples were tested using antigens 33 belonging genera Alphavirus, Flavivirus, Orthobunyavirus, Phlebovirus. The...

Between 2016 and 2018, Brazil experienced the largest sylvatic epidemic of yellow fever virus (YFV). Despite to magnitude rapid spread epidemic, little is known about YFV dispersion. The study evaluated whether squirrel monkey a good model for (YF) studies. Methods: Ten animals were infected with 1 × 106 PFU/mL YFV, one negative control. Blood samples collected daily during first 7 days at 10, 20 30 post infection (dpi) detection viral load cytokines by RT-qPCR; measurements AST, ALT, urea...
O estado do Pará vem sofrendo grandes transformações ambientais, dentre elas a exploração mineral e o desmatamento, que aumenta risco de infecção humana por arbovírus. Assim, objetiva-se demonstrar, através da presença anticorpos IgM IgG possível circulação arbovírus em residentes trabalhadores oriundos dos municípios Parauapebas, no período 2021 2022. Foram analisados 532 soros humanos pelo teste Inibição Hemaglutinação (IH) para 17 tipos diferentes (Eastern equine encephalitis otma,...
