Resistência a antimicrobianos em bactérias isoladas de suínos com sinais clínic...
Serpa, Maysa; Nascimento, Juliana Amália Fonte Bôa do; Alves, Mirian Fátima; Guedes, Maria Isabel Maldonado Coelho; Reis, Adrienny TrindadeA resistência antimicrobiana é uma questão atual e muito importante para a saúde pública, geralmente associada ao uso indiscriminado de antimicrobianos na produção animal. Diante disso, foi investigado o perfil de sensibilidade-antimicrobiana em isolados bacterianos de suínos com sinais clínicos respiratórios no Brasil. Foram estudadas 96 isolados provenientes de 51 granjas de suínos do Brasil. O...
Retrospective detection and genetic characterization of Porcine circovirus 3 (p...
Saraiva, Giuliana Loreto; Vidigal, Pedro Marcus Pereira; Assao, Viviane Sisdelli; Fajardo, Murilo Leone Miranda; Loreto, Alerrandra Nunes SaraivaPorcine circovirus 3 (PCV3) is an emerging virus that was first identified in the United States in 2016. Since its first detection, PCV3 has already been found in America, Asia, and Europe. Although PCV3 has already been described in Brazil, knowledge of its detection and sequence variation before 2016 is limited, as well as its distribution in the main swine producing regions of Brazil. In this study, 67 porci...
Virulence in murine model shows the existence of two distinct populations of Br...
Ferreira, Jaqueline Maria Siqueira; Drumond, Betânia Paiva; Guedes, Maria Isabel Maldonado Coelho; Xavier, Marcelo Antônio PascoalBrazilian Vaccinia virus had been isolated from sentinel mice, rodents and recently from humans, cows and calves during outbreaks on dairy farms in several rural areas in Brazil, leading to high economic and social impact. Some phylogenetic studies have demonstrated the existence of two different populations of Brazilian Vaccinia virus strains circulating in nature, but little is known about their biological ch...
Prevalence of bluetongue virus antibodies in sheep from Distrito Federal, Brazil
Dorneles, Elaine Maria Seles; Gonçalves, Vitor Salvador Picão; Morcatti, Fernanda Coura; Guimarães, Alessandro de Sá; Lobato, Zélia Inês PortelaThe aims of the present study were to determine the prevalence of bluetongue virus antibodies in sheep from Distrito Federal. Sera from 606 sheep of 18 herds were submitted to the agar-gel immunodiffusion for bluetongue virus antibodies. The prevalences of bluetongue infection found in Distrito Federal were 100% (CI 95%: 84.67 to 100.00) for flocks and 52.37% (389/606) (CI 95%: 35.76 to 68.98) for animals. Thus...
