Abstract In the book A “pacificação” dos sentidos: mídia e violência na cidade em disputa, researcher Kleber Mendonça analyses , from the RJTV newscast, how media coverage legitimized the actions of the State during the pacification process of favelas in Rio de Janeiro. Through discourse analysis, the author reveals the strategies adopted by the media to achieve consensus and silencing in the peak moments of the occupations.
Resumo Em A “pacificação” dos sentidos: mídia e violência na cidade em disputa, o pesquisador Kleber Mendonça analisa, a partir de edições do RJTV, como a cobertura midiática legitimou as ações do Estado no processo de pacificação de favelas cariocas. Ao empregar metodologicamente a análise do discurso, o autor revela as estratégias adotadas pela mídia para gerar consensos e silenciamentos no auge das ações de ocupação.
Introduction Arboviruses are an important public health problem in Brazil, in especially flaviviruses, including the Saint Louis encephalitis virus (SLEV) and the Rocio virus (ROCV), are especially problematic. These viruses are transmitted to humans or other vertebrates through arthropod bites and may cause diseases with clinical manifestations that range from asymptomatic infection, viral hemorrhagic fever to encephalitis. Methods A serological survey of horses from various regions of Brazil using an enzyme-linked immunosorbent assay (ELISA) with recombinant SLEV domain III peptides and ROCV E protein as antigens. Results Overall, 415 (55.1%) of the 753 horses that were screened were seropositive for flavivirus and, among them, monotypic reactions were observed to SLEV in 93 (12.3%) and to ROCV in 46 (6.1%). These results suggested that these viruses, or other closely related viruses, are infecting horses in Brazil. However, none of the studied horses presented central nervous system infection symptoms. Conclusions Our results suggest that SLEV and ROCV previously circulated among horses in northeast, west-central and southeast Brazil.
Since the emergence of West Nile virus (WNV) in North America in 1999, there have been several reports of WNV activity in Central and South American countries. To detect WNV in Brazil, we performed a serological survey of horses from different regions of Brazil using recombinant peptides from domain III of WNV. Positive samples were validated with the neutralisation test. Our results showed that of 79 ELISA-positive horses, nine expressed WNV-specific neutralising antibodies. Eight of the infected horses were from the state of Mato Grosso do Sul and one was from the state of Paraíba. Our results provide additional evidence for the emergence of WNV in Brazil and for its circulation in multiple regions of the country.
