Neurovirulence of mumps virus: intraspinal inoculation test in marmosets.
An intraspinal inoculation test of mumps virus using marmosets was performed in order to develop a neurovirulence test of mumps vaccines. In the group inoculated with non-neurovirulent Jeryl Lynn vaccine strain at 10(2.0) pfu/dose, there were only minimal histopathological changes in 3 of the 5 marmosets. In contrast, all marmosets inoculated with neurovirulent Urabe and NK-M46 vaccine strains developed extensive encephalitis and meningitis. Thus, this marmoset model, which can distinguish between non-neurovirulent and neurovirulent vaccine strains, is useful for evaluating neurovirulence of vaccine strains and elucidating the molecular pathogenesis of mumps.
