Researchers at the University of São Paulo's Biomedical Science Institute (ICB-USP) in Brazil have
discovered a new virus in a migratory bird species. This is such a rare find that it can be considered a stroke of luck, especially because the virus in question is avian paramyxovirus 15, which belongs to the same family as avian paramyxovirus 1, the pathogen that causes Newcastle disease. This disease is not a health hazard for humans but can be lethal to wildfowl and domestic poultry.
"We perform active monitoring of viruses in migratory birds. I was looking for Newcastle disease virus, a type 1 avian paramyxovirus, and my colleague Jansen de Araújo aimed to detect avian influenza virus for his research project. Finally, we found a co-infection by two viruses, one of which was totally unknown until then," said Luciano Matsumiya Thomazelli, a researcher at ICB-USP's Clinical & Molecular Virology Laboratory.
Since 2005, the lab team has been going into the field to perform epidemiological surveillance in different parts of Brazil as part of the Viral Genetic Diversity Network (VGDN), funded by FAPESP and headed by Professor Edison Luiz Durigon.
Their goal is to detect the presence of avian influenza virus and Newcastle disease virus, among others, in birds and other wild animals. In addition to monitoring, they aim to assess the risk of new strains arriving in Brazil. The samples collected by the team are stored in freezers at -80 °C and used in scientific research.
