Genomic and antibody-based assays for the detection of Indian strains of nodavirus and extra small virus associated with white tail disease of .

White tail disease (WTD) of cultured is caused by nodavirus (NV) and extra small virus (XSV). Since both the viruses have small single strand RNA as genetic material with short generation time, they are more prone to mutations. Hence detection methods developed for one strain may be suboptimal for the detection of isolates from the different geographical locations.

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.

Protection of Macrobrachium rosenbergii against white tail disease by oral administration of bacterial expressed and encapsulated double-stranded RNA.

White tail disease (WTD) of cultured Macrobrachium rosenbergii is caused by M. rosenbergii nodavirus (MrNV) and an extra small virus (XSV), both present together, and the mortality rate can be as high as 100% within 2 or 3 days of infection. Possible protection of M.

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.
