papovavirus Microbiol.|pəˈpəʊvəvaɪərəs|
Also papova virus.
[See quot. 1962.]
Any of a group of small animal viruses which includes those causing polyoma, papilloma, sarcoma, and warts, the members of which consist of double-stranded DNA in an icosahedral capsid with no envelope.
1962J. L. Melnick in Science 30 Mar. 1128 In the course of work in this laboratory with papilloma (wart) virus of man, polyoma virus of mice, and vacuolating virus of monkeys, I have been made conscious of the similarities in properties between each of them and papilloma virus of rabbits. This has led me to group these viruses together in the pa'po'va virus group, the name being derived from the first two letters of each virus name: papilloma, polyoma, vacuolating, in the order in which the viruses became known. Ibid. 1129 The papova viruses contain DNA. 1969S. T. Lyles Biol. Microorganisms xxvi. 536 Papovaviruses characteristically produce warts in human infections; the most common type is the verruca vulgaris, called the common wart. 1973R. G. Krueger et al. Introd. Microbiol. xxi. 562/1 Members of the papova⁓virus group can produce tumours readily when injected into tissues of immunologically undeveloped neonatal animals and with difficulty when injected into older animals. 1977Proc. R. Soc. Med. LXX. 393/2 Dulbecco (1976) has recently considered evidence suggesting that cellular mutations may be needed for the full expression of cell transformation by papova viruses. |
