Mmsvbalb3T3 cells CCL 1632 A

Moloney murine sarcoma virus (M-MSV)-transformed non-producer cell line.

MMT 060562 cells (CCL 51) Derived from a spontaneous mammary tumor which arose in a C57BL x Af Fl hybrid female mouse.

MMV virus A strain of BK virus. Isolated from a reticulum cell sarcoma of the brain of an 11-year-old boy with Wiskott-Aldrich syndrome. Isolated by co-cultivation of brain tissue with human fetal brain cells.

mock infection Inoculation of cells or an organism with a solution not containing infectious virus. Used as a control in virus infection experiments to ascertain any possible effects of materials in the inoculum other than infectious particles.

Modoc virus (MODV) A species in the genus Flavivirus belonging to the Modoc virus group. Found in California, Oregon, Montana and Colorado, USA. There is no known arthropod vector. Isolated from the deer mouse, Peromyscus maniculatus. Not known to cause disease in humans.

moesin Membrane organizing external spike protein, a putative receptor for Measles virus.

Moju virus (MOJUV) A strain of Guama virus in the genus Bunyavirus. Isolated from sentinel mice and forest rats, also mosquitoes in Para, Brazil. Not reported to cause disease in humans.

Mojui dos Campos virus (MDCV) A tentative species in the genus Bunyavirus, not assigned to any antigenic group. Isolated from an undetermined species of bat in Para, Brazil.

Mokola virus (MOKV) A species in the genus Lyssavirus. Antigenically related to, but distinguishable from, Rabies virus. Isolated from a shrew of Crocidura sp and from children with CNS disease in Nigeria. Experimental infection often fatal in shrews. Can be transmitted from shrews to mice by biting. Pathogenic for dogs and monkeys given i.c.

Molluscipoxvirus A genus in the family Poxviridae containing a single species, Molluscum contagiosum virus. Virions are brick-shaped, 320 x 250 x 200nm containing double-stranded DNA, 200 kb in length; G+C >60%. Produces localized skin lesions containing enlarged cells with cytoplasmic inclusions. Probable species have been recognized in horses, donkeys and chimpanzees.

Molluscum contagiosum virus (MOCV)

Type species of the genus Molluscipoxvirus. An exclusively human infection, mostly of children, young adults or immunosuppressed patients. The DNA is 196-200 kb in length; G+C is 60% with inverted terminal repeats. There are 165 open reading frames, 104 of which have homologs in other poxviruses such as Vaccinia virus. Lesions are confined to the skin. Incubation period 14-50 days. Pimples develop into nodules 2mm in diameter which become pearly white and may develop an opening to reveal a white core. Lesions persist for months and may be disfiguring when combined with bacterial infections. Transmission by direct and indirect contact can cause opportunistic infection in immuno-compromised (e.g. AIDS) patients. Virus does not replicate in eggs or cell cultures. Not inhibited by vaccinia, cowpox or fowlpox antiserum and does not reactivate heat-inactivated Vaccinia virus. Not inactivated by ether or chloroform but inactivated by exposure to pH 3. Does not hemagglutinate chick or human ery-throcytes.
