Influenza B virus is a major causative agent of respiratory disease in humans. Our study of an outbreak of influenza B virus in Wenzhou from 2011 to 2014 revealed that 163 (5.58 %) of 2921 samples were influenza B positive. Sequencing of the hemagglutinin and neuraminidase genes showed substitutions at the amino acid level. Phylogenetic analysis revealed co-circulation of the B/Victoria and B/Yamagata...
Defective prophages, which are found in the genomes of many bacteria, are unable to complete a viral replication cycle and propagate in their hosts as healthy prophages. They package random DNA fragments derived from various sites of the host chromosome instead of their own genomes. In this study, we characterized a defective phage, PBP180, which was induced from Bacillus pumilus AB94180 by treatment...
