Nonhomologous RNA Recombination in Bovine Viral Diarrhea Virus: Molecular Characterization of a Variety of Subgenomic RNAs Isolated during an Outbreak of Fatal Mucosal Disease

Abstract excerpt

Four bovine viral diarrhea virus type 2 (BVDV-2) pairs consisting of cytopathogenic (cp) and noncp BVDV-2 were isolated during an outbreak of mucosal disease. Comparative sequence analysis showed that the four noncp BVDV-2 isolates were almost identical. For the cp BVDV-2 isolates, viral subgenomic RNAs were shown by Northern blot to have a length of about 8 kb, which is about 4.3 kb shorter than the genome of...
