influenza B

in·flu·en·za B

influenza caused by strains of influenza virus type B; outbreaks are usually more limited than those due to influenza virus type A, although infections by the two types are clinically indistinguishable; occasionally associated with Reye syndrome.

Influenza A (H1N1) and (H3N2) and Influenza B have circulated globally in humans since 1977.
In addition, both influenza types A and B were circulating during the study, with nearly half of infected index cases having laboratory evidence of infection with influenza B.
This accessibility restricts the potential targets to conserved structures of the ectodomains of viral transmembrane proteins HA, NA, and M2, in the case of influenza A viruses, and HA, NA, NB, and BM2, in the case of influenza B viruses.
The most notable region of conservation is the sequence around the cleavage site, particularly the HA2 N-terminal 11 aa, termed fusion peptide, which is conserved among all influenza A subtypes and differs only by 2 conservative aa replacements in influenza B virus.
Specification of receptor-binding phenotypes of influenza virus isolates from different hosts using synthetic sialylglycopolymers: non-egg-adapted human H1 and H3 influenza A and influenza B viruses share a common high binding affinity for 6'-sialyl(N-acetyllactosamine).
Similar results were obtained with the NS1 of influenza B virus (19,20).
The influenza B virus nonstructural NS1 protein is essential for efficient viral growth and antagonizes beta interferon induction.
Current influenza virus vaccines consist of 3 components: an H1N1 (hemagglutinin [HA] subtype 1; neuraminidase [NA] subtype 1), an H3N2 influenza A virus, and an influenza B virus.
