The mumps virus neurovirulence safety test in Rhesus monkeys: a comparison of mumps virus strains.
Wild type mumps viruses are highly neurotropic and a frequent cause of aseptic meningitis in unvaccinated humans. To test whether attenuated mumps viruses used in the manufacture of mumps vaccines have neurovirulent properties, a monkey neurovirulence safety test (MNVT) is performed. However, results with several mumps virus MNVTs have raised questions as to whether the test can reliably discri...
متن کاملGene-specific contributions to mumps virus neurovirulence and neuroattenuation.
Mumps virus (MuV) is highly neurotropic and was the leading cause of aseptic meningitis in the Western Hemisphere prior to widespread use of live attenuated MuV vaccines. Due to the absence of markers of virus neuroattenuation and neurovirulence, ensuring mumps vaccine safety has proven problematic, as demonstrated by the occurrence of aseptic meningitis in recipients of certain vaccine strains...
متن کاملMumps vaccine virus strains and aseptic meningitis.
Mumps immunization can easily be included in national schedules, particularly if combined with measles or measles and rubella vaccines, but debate continues concerning the relative safety of various licensed mumps vaccine strains. The opportunities for control of mumps are also being affected by differences in the cost of the vaccines prepared with different strains of mumps virus. The present ...
متن کاملResponse to experimental infection with mumps virus in rhesus monkeys.
Experiments were conducted in which rhesus monkeys were infected with mumps virus by inoculation into the parotid gland. Virus was isolated from buccal swab specimens from animals up to 6 days after inoculation. Immunofluorescence staining for mumps antigen was positive, and infectious virus was recovered from tissue biopsies of inoculated glands. Histological examination of biopsied glands rev...
متن کاملImmunocyte response to experimental mumps virus infection in Rhesus monkeys.
Nineteen rhesus monkeys were inoculated with mumps virus by retrograde ductal instillation into the parotid gland. Evidence of infection was obtained in all instances. Virus was isolated from buccal swabbings and parotid biopsies for 1 week after inoculation. A vigorous serum-neutralizing antibody response occurred within 3 weeks, and there was marked monocytic infiltration of the parotid strom...
