ELECTROPHORETIC ANALYSIS OF INFECTIOUS BURSAL , DISEASE VIRUS RNA

Abstract

Nucleic acids extracted front four field isolates (two each from vaccinated and unvaccinated flock,) and a vaccine strain of infections bursal disease virus were electrophoresed in 0.8% agarose gel to compare the migration pattern of RNA. /All the five isolates showed two distinct bands indicating the bisegmentation of the viral RNA. No difference in the migration pattern of viral RNA from various isolates was detected.
