A DNA tumour virus with very small genome (of the Papovaviridae). Polyoma was isolated from mice, in which it causes no obvious disease, but when injected at high titre into baby rodents, including mice, causes tumours of a wide variety of histological types (hence poly-oma). In vitro, infected mouse cells are permissive for virus replication, and thus are killed, whilst hamster cells undergo abortive infection, and at a low frequency become transformed.
