Implication

May inform multivalent rotavirus vaccine design; leaves open translation from animal models to humans.

Key Points

This research aims to identify which viral gene segments induce protective immune responses against rotavirus serotypes.
Used reassortant rotaviruses from MA-104 cells coinfected with simian strain SA11 and bovine strain NCDV.
Tested the protective response from vp3 and vp7 proteins in adult mice through oral immunization.
Constructed reassortant viruses containing proteins from different parent strains to assess immune effects.
Adult mice developed neutralizing antibodies to both vp3 and vp7 after inoculation with strain Eb.
Passive protection against UK challenge was observed in progeny from mouse dams immunized with gene 9 from NCDV.
Reassortant viruses induced protective immune responses against both parental serotypes through oral immunization.

Structured PICO

Population

Adult mice and mouse dams used to study protective immune responses to reassortant rotaviruses.

Intervention

Oral immunization with reassortant rotaviruses containing structural proteins vp3 and vp7 from different parents (SA11, NCDV, Eb, UK)

Outcome

Induction of neutralizing antibodies and passive protection of progeny against rotavirus challengesurrogate

Reassortant rotaviruses expressing vp3 and vp7 from different parental strains can induce protective immunity against both serotypes, informing future rotavirus vaccine strategies.
