Detection of sapovirus in brazilian pig farms / Detecção de sapovírus em criações de suínos brasileiras

Sapoviruses (Caliciviridae) are considered important agents of gastroenteritis worldwide affecting animals and humans. In pig farming, the epidemiology is not completely understood because it can affect all stages of production, with symptomatic (diarrhea) or asymptomatic pigs. The aim of our study was to investigate Sapovirus occurrence in Brazilian pig farms. A total of 166 fecal samples of pigs, with different ages, from Minas Gerais, São Paulo, and Mato Grosso States were submitted to RT-PCR reactions and confirmed with nucleotide sequencing of Sapovirus RdRp gene. Six (3.61%) samples were positive and four had partial RdRp gene sequenced, putatively belonging to GVII.1 genogroup, also reported in swine herds in Brazil.

Sapovírus (Caliciviridae) são considerados importantes agentes causadores de gastroenterites em todo o mundo, afetando animais e humanos. Na suinocultura, sua epidemiologia ainda não foi totalmente esclarecida, pois pode afetar todas as fases da produção, com suínos sintomáticos (diarreia) ou assintomáticos. O objetivo do nosso estudo foi investigar a ocorrência de Sapovírus em granjas de suínos brasileiras. Um total de 166 amostras fecais de suínos, com diferentes idades, dos estados de Minas Gerais, São Paulo e Mato Grosso foram submetidas a reações de RT-PCR e confirmadas com sequenciamento de nucleotídeos do gene RdRp do Sapovírus. Seis (3,61%) amostras foram positivas e quatro delas tinham sequenciamento parcial do gene RdRp, supostamente pertencente ao genogrupo GVII.1, previamente relatado em rebanhos suínos no Brasil.

Coronaviruses: there and back again

With the raise of SARS-CoV-2 in late 2019 and the associated COVID-19 pandemics, much of the knowledge gathered from decades on research on other coronavirus species that use humans and other animals as hosts is invaluable to help counteract the burden of this new disease. This review ais to bring the highlights on coronavirus Biology and the most frequent diseases they might cause, serving rather as an introduction to the field.
