Applications of IGY antibodies to influenza a virus detection in infected cells by immunocytochemistry. Repositório Alice
SILVA, M. C. da; SCHAEFER, R.; GAVA, D.; SOUZA, C. K.; VENANCIO, E. J..
Introduction and objectives: Influenza is a disease caused by infection of the host respiratory tract by influenza type A virus that affects a wide variety of species, including human, swine, equine, poultry and sea mammals. The viral RNA is encapsidated by the nucleoprotein (NP), which is a highly conserved protein among influenza A viruses. Detection of influenza virus can be accomplished by assessing specific immune response to the virus, by direct detection of viral RNA or virus antigen in infected tissues. Some diagnostic tests use antibodies produced in mammals to influenza virus detection. However, due to high cost and concerns related to animal welfare, alternative production of antibodies in mammals has been described. The immunoglobulin Y (IgY)...

Innate immunity in chicken lines developed by Embrapa Suínos e Aves: antimicrobial activity of macrophages and serum. Repositório Alice
SILVA, M. C. da; COSTA, I. C.; NAKAZATO, G.; PINHEIRO, J. W.; LEDUR, M. C.; LOYOLA, W.; VENANCIO, E. J..
Abstract: The objective of this study was to compare the antimicrobial activity of macrophages and serum in laying hen (MM, CC, and CCc) and broiler chicken lineages (TT and LL). Macrophages were evaluated for phagocytic and antimicrobial activity. Microbicidal serum activity was evaluated by the resistance test for serum and the agar test. The results showed that phagocytic activity was higher in males of the MM strain, with 13% of macrophages presenting phagocytosis, while the other lineages studied, and even female MM, presented a rate of 6% of phagocytic cells. However, antimicrobial activity in macrophages from males of CCc lineage and females of TT lineage were higher, eliminating more than 30% of the Salmonella enterica inoculum, while in the other...
