ABSTRACT
Background: \r\n', u'Rotavirus is the major important cause of infectious infantile gastroenteritis and diarrhea, especially the children aged 6 months to 24 months. Some efforts made to provide safe water and cultivate the hygiene have not reduced the diarrhea caused by rotaviruses. Develope a vaccine agaisnt this virus is of high importance. A question about the production of this kind of vaccine targeted athow to make human rotaviruses strains adapt cultured cells.\r\n', u'Objectives\r\n', u'To determine the multiplicity of infection (MOI) of human rotaviruses strains in vero cell.\r\n', u'Subjects and method: \r\n', u'The multiplicity of infection of Human rotaviruses strains (G1 P8, G1P4, and G4P6) were selected and the CDC- Atlanta US supplied the vero cell.Use vero cells cultivate, temper the vero cell and, applying direct immunofluorescence to determine the multiplicity of G1P8, G1P4, C4P6.\r\n', u'Results:\r\n', u'The MOI of G1P8, G1P4 and C4P6 are 0.02 ffu/cell, 0.15ffu/cell, and 0.35 ffu/cell, respectively.\r\n', u'Conclusion:\r\n', u'Using the vero cell to multiple the rotaviruses is the effective part during the production of vaccines against rotaviruses. The MOI of human rotaviruses strains G1P8, G1P4 and G4P6 are in order:0,02 ffu/cell, 0,15ffu/cell, and 0,35% ffu/cell. \r\n', u'
