Recombinant viral proteins delivered orally through inactivated bacterial cells induce protection in Macrobrachium rosenbergii (de Man) against White Tail Disease.

White tail disease (WTD) is a disease of Macrobrachium rosenbergii caused by Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV) with the potential to devastate the aquaculture industry. The present study aimed to explore the possible protection of M. rosenbergii against the disease by oral administration of bacterially expressed recombinant capsid proteins of MrNV and XSV.

Genetic analysis of RNA1 and RNA2 of Macrobrachium rosenbergii nodavirus (MrNV) isolated from India.

Macrobrachium rosenbergii nodavirus (MrNV) is responsible for the newly emerging catastrophic disease known as white tail disease (WTD) in M. rosenbergii. The complete sequence of RNA2 (1175 bp) and 3126 bp region of RNA1 of an Indian strain of MrNV was generated.
