| Moloney murine sarcoma virus | <molecular biology, virology> Replication defective retrovirus, source of the oncogene v mos, responsible for inducing fibrosarcomas in vivo and transforming cells in culture. (18 Nov 1997) |
| moloney sarcoma virus | A replication-defective murine sarcoma virus (sarcoma viruses, murine) isolated from a rhabdomyosarcoma by moloney in 1966. (12 Dec 1998) |

| monkey B virus | A herpesvirus, in the family Herpesviridae, affecting Old World monkeys, that is very similar morphologically to herpes simplex virus; fatal infection may occur in humans following the bite of an infected monkey, although other modes of transmission have also been documented. Synonym: monkey B virus. (05 Mar 2000) |
| monkeypox virus | A species of orthopoxvirus causing an epidemic disease among captive primates. (12 Dec 1998) |
| WEE virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in the western United States and parts of South America; it occurs naturally, usually as a symptomless infection in birds, but causes western equine encephalomyelitis in horses and humans following transfer by the bites of mosquitoes, chiefly Culex tarsalis. Synonym: WEE virus. (05 Mar 2000) |

| western equine encephalomyelitis virus | A group A arbovirus of the genus Alphavirus, family Togaviridae, occurring in the western United States and parts of South America; it occurs naturally, usually as a symptomless infection in birds, but causes western equine encephalomyelitis in horses and humans following transfer by the bites of mosquitoes, chiefly Culex tarsalis. Synonym: WEE virus. (05 Mar 2000) |
