　　A recent study published in the American online journal Microbiology found that the swine flu virus H1N1 infects dogs and genetically recombines with other viruses in dogs. The subtypes of influenza viruses in dogs are increasing. Researchers say that poultry and pigs are the main reservoirs for the genetic diversity of influenza viruses, while dogs and horses have low levels of influenza A viruses and rarely infect humans. Previous studies have shown that the main types of influenza A viruses circulating in dogs are H3N8 and H3N2,

　　Researchers from Guangxi University in China and Mount Sinai School of Medicine in the United States extracted 16 influenza virus strains from dogs living in the Guangxi Zhuang Autonomous Region of China, sequenced them, and identified 3 swine influenza virus fragments. Gene. The swine influenza virus H1N1 that infects dogs recombined with the canine influenza virus H3N2 to produce three new canine influenza viruses. Adolf García Suster of Mount Sinai School of Medicine who participated in the study said that canine influenza viruses are diverse, and viral genes can combine with each other and bring danger to humans. The researchers said that in the future, human serum will be used to determine whether the human body is immune to the canine influenza virus. Garcia-Sast said that if people are immune, the risk of the new virus spreading to people can be reduced. Paul Degarde, a professor of virology at the University of Edinburgh in the United Kingdom, commented that influenza viruses from other animals may infect dogs. This does not necessarily mean that these viruses will spread in dogs, and these viruses are also difficult to infect other animals. No one has been infected with these canine influenza viruses.
