Five Indian isolates of egg drop syndrome (EDS) 1976 virus and the reference strain 127 were compared by restriction enzyme analysis of viral DNA, and the hexon gene amplified by polymerase chain reaction. Using these techniques, no differences were seen among these viruses. However, partial sequencing of the hexon gene revealed major differences (4.6%) in(More)
The virulence of strains of egg drop syndrome (EDS) 1976 virus for the female reproductive tract of chickens was assessed in vitro using oviduct organ cultures (OOC) prepared from precociously induced oviducts in young chicks by oestrogen treatment. Ciliostasis, haemagglutination and virus titres in infected OOC supernatants, histology and immunoperoxidase(More)
MOTIVATION The detection of subtle genomic allelic imbalance events has many potential applications. For example, identifying cancer-associated allelic imbalanced regions in low tumor-cellularity samples or in low-proportion tumor subclones can be used for early cancer detection, prognostic assessment and therapeutic selection in cancer patients. We(More)
Stunted growth in pond-reared Litopenaeus vannamei was observed in different farms located in Tamil Nadu and Andhra Pradesh, India. No mortality was associated with stunted growth. PCR assay on these samples revealed the presence of Enterocytozoon hepatopenaei (EHP) in stunted shrimp. Tissue distribution of EHP in naturally and experimentally infected(More)
Whiteleg shrimp, Litopenaeus vannamei, with clinical sign of muscle opaqueness with reddish colour at the distal abdominal segments were observed in farms located in West Bengal State, India. The mortality of shrimp in all disease outbreak ponds ranged from 20% to 50%, and mortality increased gradually. The RT-PCR assay of these samples using primer sets(More)
Mouse monoclonal antibodies (mAbs) were produced against an Indian isolate of egg drop syndrome (EDS) virus and characterized. Four hybridoma clones were secreting mAbs that bound to a 100 kDa protein, presumably the hexon protein. These mAbs were found to cross-react with two other Indian isolates of EDS virus and to the reference UK 127 strain. Three of(More)
In recent years, researchers have focused on viral and plant immunostimulants which could have beneficial effects in disease prevention and control in shrimp culture. At present, the application of the recombinant VP28 protein (r-VP28) and herbal immunostimulant has been considered as a more effective approach to prevent white spot syndrome (WSS) by(More)
