Figure 1From: Replication of avian, human and swine influenza viruses in porcine respiratory explants and association with sialic acid distributionVirus yields, expressed as log TCID 50 /ml, in the supernatant of the explants. Virus titers were determined at 1, 24 and 48 hpi. Each row shows the results per explant system, from NE down to LE. Each column represents the host from which the different virus subtypes were isolated: pigs, humans and birds. Each value is the mean of three experiments, bars show the S.D. NE: nasal explants, TE: tracheal explants, BE: bronchial explants, LE: lung explantsBack to article page
