effect of polycations on growth and dissemination of the encephalomyocarditis virus in mice. | pathogenicity of the encephalomyocarditis (emc) virus for adult mice was increased when polycations of diverse type were mixed with virus and inoculated by the subcutaneous or intraperitoneal routes. diethylaminoethyl (deae) dextran, hexadimethrine (polybrene), polymyxin b, polylysine, and calf thymus histone in various concentrations stimulated multiplication of virus in tissues at the injection site and enhanced entry of virus into the blood. the nonpathogenic r(+) variant of emc which grows l ... | 1967 | 4316242 |
distribution of cell receptors and simple sugar inhibitors during encephalomyocarditis virus-cell union. | encephalomyocarditis (emc) virus was studied for ability to agglutinate erythrocytes of various species. human, rat, and guinea pig erythrocytes, as well as those from young rabbits, were readily agglutinated. cells from older rabbits absorbed virus poorly, and showed little agglutination. uptake of virus by rabbit brain also diminished with age. various mouse tissues absorbed virus about equally well. hemagglutination-inhibition studies demonstrated that a number of simple sugars, particularly ... | 1967 | 4318947 |
separation of plaque-type variants of encephalomyocarditis virus by chromatography on calcium phosphate. | encephalomyocarditis (emc) virus (k-2 strain) was separated into two distinct peaks of optical density by chromatography on calcium phosphate, eluting at 0.17 and 0.31 m, respectively. the virus in these peaks could not be distinguished by infectivity (plaque-forming units), hemagglutinin activity, electron microscopic appearance, sedimentation coefficient, or base ratios. however, variants producing large plaques predominated in the first peak eluted, whereas variants producing small plaques we ... | 1967 | 4318950 |
interaction of encephalomyocarditis virus with ultraviolet-irradiated host cells. | ultraviolet light (uv) impaired the capacity of l cells to support growth of encephalomyocarditis virus. the loss of capacity was partially restored by high multiplicity of infection (moi). this phenomenon was not due to an increased probability of an infectious virus particle reaching a site of replication undamaged by uv, since uv-inactivated virus at high moi induced restoration of the capacity to support multiplication of nonirradiated virus adsorbed at low moi. multiplicity reactivation of ... | 1967 | 4318958 |

destruction of l cells by mengo virus: use of interferon to study the mechanism. | interferon, when added to l cells, inhibited the synthesis of infectious mengo viral ribonucleic acid, hemagglutinins, and infectious virus by 85 to 95%. serum-blocking antigens were also reduced by the action of interferon, but threefold excess amounts of these antigens accumulated in interferon-treated cultures above the amounts expected for the quantity of infectious virus that was produced in these cultures. radioautographic analysis showed that 28 to 36% of the cells of an interferon-treate ... | 1968 | 4301505 |

replication of mengovirus in hela cells preinfected with nonreplicating poliovirus. | the replication of mengovirus in hela cells preinfected with poliovirus in the presence of 10(-3) m guanidine was investigated. although host cell protein synthesis is inhibited by the presence of nonreplicating poliovirus, it is found that mengovirus ribonucleic acid (rna) and protein synthesis proceed normally under the same conditions. furthermore, no effects on mengovirus growth by poliovirus can be detected either when mengo protein synthesis is interrupted by acti-dione or when its rna syn ... | 1968 | 4302186 |

mengovirus replication in novikoff rat hepatoma and mouse l cells: effects on synthesis of host-cell macromolecules and virus-specific synthesis of ribonucleic acid. | novikoff cells (strain n1s1-67) and l-67 cells, a nutritional mutant of the common strain of mouse l cells which grows in the same medium as n1s1-67 cells, were infected with mengovirus under identical experimental conditions. the synthesis of host-cell ribonucleic acid (rna) by either type of cell was not affected quantitatively or qualitatively until about 2 hr after infection, when viral rna synthesis rapidly displaced the synthesis of cellular rna. the rate of synthesis of protein by both ty ... | 1968 | 4176992 |

factors modifying host resistance to viral infection. 3. effect of whole body x-irradiation on experimental encephalomyocarditis virus infection in mice. | the resistance of mice to encephalomyocarditis (emc) virus was markedly decreased by prior exposure to whole body x-irradiation. in contrast to non-irradiated controls, the course of emc virus infection in x-irradiated animals was characterized by (a) an enhanced mortality, (b) shortening of the incubation period, (c) higher levels of virus in the blood during the viremic phase and persistence of the viremia until death, (d) failure to develop detectable serum levels of neutralizing antibody, an ... | 1968 | 4297630 |

virus-directed protein synthesis in different animal and human cells. | the relative proportions of viral gene products (viral proteins) that are synthesized in different types of animal cells infected with the same rna virus inoculum were compared. the relative rates of synthesis of the various virus proteins late in infection were remarkably constant regardless of cell type infected. this was true in cell lines that produced only small amounts of virus and virus proteins, as well as in those that gave large yields of viruses and virus proteins. | 1968 | 4297294 |

contrasting effects of polycations on plaquing efficiency of encephalomyocarditis virus variants. | polycation treatment of l cell monolayers affected plaquing efficiency of both the r(+) and r variants of the encephalomyocarditis virus. plaque formation by r(+) variant was decreased markedly by three structurally different types of synthetic basic polymers, diethylaminoethyl dextran, hexadimethrene (polybrene), and basic polyamino acids. in contrast, these same substances increased substantially the number of plaques formed by the r variant. the effect on the two variants was observed when po ... | 1969 | 4306302 |

the role of individual spleen cells in the interferon response of the intact mouse. | a method is described for the detection of interferon production by individual spleen cells of mice after intravenous virus infection. although mouse spleen plays a major role in the total interferon response to newcastle disease virus, the number of spleen cells participating is a small fraction of the total, suggesting that interferon formation is to some extent a specialized cell function. monolayers of mouse embryo cells, after brief contact with agar-suspended spleen cells from interferon-p ... | 1969 | 4307872 |
propagation of mm virus in l cells. | mm virus (mouse-brain stock) replicated to a limited extent in l cells without cytopathic effects; the average yield was less than 1 plaque-forming unit/cell. passage in bhk-21 cells resulted in mm virus [mm(bhk)] which replicated to high titers (200 to 300 plaque-forming units/cell) in l cells with complete cytopathic effects. appearance of mature mm(bhk) virus in l-cell cultures begins 4 hr after infection and is completed by 8 hr. release of mature virus was slow (less than 1% at 8 hr) but wa ... | 1969 | 4307880 |
propagation of mm virus in continuous cell lines. | baby hamster kidney (bhk), mccoy, and l cell lines were found to be suitable for isolation of mm virus from infected mouse brain tissue. the virus was recovered in high titer in the first passage in bhk and mccoy cells, with concomitant cytopathic effect (cpe). in l cells, virus yield was lower than in the other two cell lines and cpe was incomplete. adaptation of the virus to bhk and mccoy cells by serial passages was evidenced by accelerated development of the cpe and increase in the virus tit ... | 1969 | 4307881 |
effect of ultraviolet irradiation and actinomycin d on polyoma virus replication in mouse embryo cell cultures. | ultraviolet irradiation and actinomycin d impair the capacity of mouse embryo (me) cells to support the replication of polyoma virus, but not of encephalomyocarditis (emc) virus. the loss in capacity for polyoma virus synthesis was an "all-or-none" effect and followed closely upon the loss in cellular capacity for clone formation. cells treated with either agent produced polyoma "t" antigen, but did not synthesize polyoma structural protein. infection of untreated me cells with polyoma virus pro ... | 1969 | 4307903 |

influence of statolon on resistance of mice to influenza. | various interferon inducers are known to elicit protection against lethal or infecting doses of certain viral agents. because of the relatively high morbidity rate of influenza and its seasonal occurrence, we wished to determine whether statolon-induced interferon might be effective in controlling this disease. mice were treated intraperitoneally with statolon and challenged with influenza a(2) virus by the intranasal route. although interferon was present in the serum at the time of virus admin ... | 1969 | 4308934 |

mengovirus-induced cytopathic effect in l-cells: protective effect of interferon. | the effect of interferon on mengovirus-induced cytopathic effect (cpe) in l cells, the cut-off of host-cell protein synthesis, and production of mature virus were found to be dependent on the concentration of interferon. cpe and inhibition of host protein synthesis were not affected until the concentration of interferon was increased 100-fold over that required to reduce viral yields by 90%. | 1969 | 4309883 |
