adenovirus, parainfluenza virus and respiratory syncytial virus antibodies in the sera of jamaicans. | surveys for respiratory virus antibodies in the jamaican population have shown that adenovirus, respiratory syncytial virus and parainfluenza types 1 and 3 virus antibodies are acquired early in life. the incidence of haemagglutination-inhibiting antibodies to parainfluenza viruses increases rapidly with age and almost all adults possess parainfluenza type 3 antibody, usually in high titre. parainfluenza type 1 antibodies are only slightly less common. complement-fixing antibodies to the adenovi ... | 1972 | 4341999 |
studies of the mechanism of enhancement of human adenovirus infection in monkey cells by simian virus 40. | the defect which prevents human adenovirus replication in monkey cells and the mechanism whereby this restriction is overcome by coinfection with simian virus 40 (sv40) have been studied. adenovirus capsid proteins are not synthesized efficiently in monkey cells in the absence of sv40. adenovirus "enhancement" by sv40 was found to be the product of increased efficiency of replication by a small percentage of cells. this enhancement effect apparently occurred only when sv40 and adenovirus infecte ... | 1972 | 4342239 |
synthesis of viral ribonucleic acid during restricted adenovirus infection. | the mechanism by which simian virus 40 converts the abortive adenovirus type 7 infection of monkey cells into an efficient lytic infection has been investigated. analysis of ribonucleic acid (rna) synthesis during unenhanced and enhanced infection of monkey cells has shown that adenovirus rna synthesized in the abortive infection contains both "early" and "late" sequences. in hybridization competition experiments, early adenovirus rna from human cells prevented the hybridization of only 20% of t ... | 1972 | 4342240 |

pathology of exfoliated oropharyngeal epithelial cells infected with wild-type adenovirus. | adenovirus disease was diagnosed in 2 hr by staining exfoliated infected oropharyngeal cells with fluorescein-tagged rabbit antisera to adenovirus types 4 and 7. the method was as sensitive as the standard virus isolation procedures, but serological cross reactions were observed. viral antigens were detected in both the nucleus and cytoplasm of infected cells. infection was accompanied by the outpouring of large numbers of polymorphonuclear leukocytes and smaller numbers of mononuclear cells. th ... | 1972 | 4342841 |

cleavage of simian virus 40 dna at a unique site by a bacterial restriction enzyme. | the r(1) restriction endonuclease of escherichia coli converts covalently-closed circular simian virus 40 (sv40) dna to unit-length linear duplex molecules. cleavage occurs at a unique site, since denaturation and renaturation of these linear molecules yield linear but no circular molecules. the distance from the cleavage site to the sv40 dna sequence contained in the adenovirus-sv40 hybrid, ad2(+)nd(1), is 0.11 of the length of sv40 dna. t4 gene 32 protein binds to sv40 dna in a region 0.45 of ... | 1972 | 4343967 |
evidence for a transcription-control region of simian virus 40 in the adenovirus 2--simian virus 40 hybrid, ad2+nd 1 . | the complementary dna strands of the nondefective adenovirus 2 (ad2)-simian virus 40 (sv40) hybrid virus, ad2(+)nd(1), were separated by isopycnic banding in a cscl density gradient in the presence of synthetic polyribonucleotides. separated strands were used in dna-rna hybridization reactions with rna from cells productively infected by ad2 or sv40, and with complementary sv40 rna transcribed asymmetrically in vitro. about five times as much ad2 rna hybridized to the light stand of ad2(+)nd(1) ... | 1972 | 4343969 |
adenovirus susceptibility to human interferon during one-step replication. | susceptibility of adenovirus types 2, 7, and 12 to human interferon was measured in three human diploid cell strains during a single-cycle infection. although the relative susceptibility of adenovirus to interferon varied in these cell strains, the final yield of each type in each cell strain decreased as the interferon dose increased. on the other hand, wide difference in interferon susceptibility of adenoviruses and vesicular stomatitis virus (vsv) was noted, as interferon doses above 100 unit ... | 1972 | 4344095 |
