The new flu virus mutation can be transmitted from dogs and cats to humans, as shown by a study conducted over 10 years Sung Tae subsections, a professor at Korea University, said phys.org.
Previously, it was found that canines can be guests of H3N2 subtype, known here as "canine influenza virus» (CIV, for its acronym in English). During a pandemic of swine flu, the H1N1 strain of the dog also suffered. According to the words of the song, two subtypes can interact, producing a new variant called «CIVmv».
The study found that the dogs CIVmv guests can infect ferrets, which are used as substitutes for people whose experiments- antivirus protection mechanisms similar to people: so we can assume that the virus also it is threatening our species.
The danger is lack of immunity against the new strain, says Song. Despite trying to develop a vaccine, the task is complicated by the intensity CIVmv mutations.
Meanwhile, it has already demonstrated the high infectiousness of the virus. In one case studied Korean scientist, she was transferred to cats shelter where 100% of the animals were infected and 40% died.
CIVmv could become endemic virus in domestic animals closest to humans, warn songs. Another threat to the & # 39 is its ability to evolve. "Preexisting CIV may recombine or rearrangement with a human influenza virus and lead to a & # 39; the emergence of new viruses, which, in turn, can lead to unique pandemics, "said the researcher.
Full study results will be presented at the annual conference of the Society of Microbiology in Belfast (United Kingdom) April 10.
