Pathogenicity of GI-23 Avian Infectious Bronchitis Virus Strain Isolated in Brazil [PDF]
IBV variants belonging to the GI-23 lineage have circulated since 1998 in the Middle East and have spread to several countries over time. In Brazil, the first report of GI-23 occurred in 2022.

A polyvalent virosomal influenza vaccine induces broad cellular and humoral immunity in pigs [PDF]
Background Influenza A virus (IAV) is endemic in pigs globally and co-circulation of genetically and antigenically diverse virus lineages of subtypes H1N1, H1N2 and H3N2 is a challenge for the development of effective vaccines.

Differential expression of miRNAs associated with pectoral myopathies in young broilers: insights from a comparative transcriptome analysis [PDF]
Introduction White Striping (WS) and Wooden Breast (WB) pectoral myopathies are relevant disorders for contemporary broiler production worldwide. Several studies aimed to elucidate the genetic components associated with the occurrence of these myopathies.

Fatores de risco associados ao desempenho reprodutivo da fêmea suína
Durante um ano foi realizado um estudo epidemiológico em 10 sistemas de produção de suínos (produtores de leitões ou ciclo completo), com o objetivo de investigar os fatores de risco que melhor explicam as variações na produtividade da fêmea suína.
