Murine polyomavirus (also known as mouse polyomavirus, Polyomavirus muris, or Mus musculus polyomavirus 1, and in older literature as SE polyoma or parotid tumor virus; abbreviated MPyV) is an unenveloped double-stranded DNA virus of the polyomavirus family. The first member of the family discovered, it was originally identified by accident in the 1950s.[2][3] A component of mouse leukemia extract capable of causing tumors, particularly in the parotid gland, in newborn mice was reported by Ludwik Gross in 1953[4] and identified as a virus by Sarah Stewart and Bernice Eddy at the National Cancer Institute, after whom it was once called "SE polyoma".[5][6][7] Stewart and Eddy would go on to study related polyomaviruses such as SV40 that infect primates, including humans. These discoveries were widely reported at the time and formed the early stages of understanding of oncoviruses.[8][9]
