Detection of reassortant influenza B strains from 2004 to 2015 seasons in Barcelona (Catalonia, Spain) by whole genome sequencing.

ABSTRACT:

Background

Influenza B viruses (FLUBV) have segmented genomes which enables the virus to evolve by segment reassortment. Since the divergence of both FLUBV lineages, B/Victoria/2/87 (FLUBV/VIC) and B/Yamagata/16/88 (FLUBV/YAM), PB2, PB1 and HA have kept the same ancestor, while some reassortment events in the other segments have been reported worldwide. The aim of the present study was to find out reassortment episodes in FLUBV strains detected in cases attended at Hospital Universitari Vall d'Hebron and Hospital de la Santa Creu i Sant Pau (Barcelona, Spain) from 2004 to 2015 seasons.

Methods

From October 2004 to May 2015, respiratory specimens were received from patients with respiratory tract infection suspicion. Influenza detection was carried out by either cell culture
