Figure 7From: Genetic and biological characterisation of an avian-like H1N2 swine influenza virus generated by reassortment of circulating avian-like H1N1 and H3N2 subtypes in DenmarkNasal virus excretion. Nasal virus excretion measured with quantitative real time RT-PCR detecting the matrix gene. Group 1 pigs were inoculated post inoculation day (PID) 0 with H1N1 and group 2 pigs were inoculated PID 0 with H1N2 (stapled line).Back to article page
