However, experiments to understand reassortment in pigs in detail have been limited because experiments with regular-sized pigs are difficult to perform. Miniature pigs have been used as an experimental animal model, but they are still large and require relatively large cages for housing. The microminipig is one of the smallest miniature pigs used for experiments. Introduced in 2010, microminipigs weigh around 10 kg at an early stage of maturity (6 to 7 months old) and are easy to handle. To evaluate the microminipig as an animal model for influenza A virus infection, we compared the receptor distribution of 10-week-old male pigs (Yorkshire Large White) and microminipigs. We found that both animals have SA\u03b12,3Gal and SA\u03b12,6Gal in their respiratory tracts, with similar distributions of both receptor types. We further found that the sensitivity of microminipigs to influenza A viruses was the same as that of larger miniature pigs. Our findings indicate that the microminipig could serve as a novel model animal for influenza A virus infection.<\/jats:p>\n          <jats:p>\n            <jats:bold>IMPORTANCE<\/jats:bold>\n            The microminipig is one of the smallest miniature pigs in the world and is used as an experimental animal model for life science research. In this study, we evaluated the microminipig as a novel animal model for influenza A virus infection. The distribution of influenza virus receptors in the respiratory tract of the microminipig was similar to that of the pig, and the sensitivity of microminipigs to influenza A viruses was the same as that of miniature pigs. Our findings suggest that microminipigs represent a novel animal model for influenza A virus infection.\n
