Figure 10From: Enhanced replication of avian-origin H3N2 canine influenza virus in eggs, cell cultures and mice by a two-amino acid insertion in neuraminidase stalk Viral RNA loads in some tissues and swabs of chickens inoculated with r-06 ( ) and r-06/NA2 ( ) strains at 2 dpi. Five chickens were chosen randomly and euthanized from each group. Each dot represents viral RNA load in an organ sample from one chicken. Viral loads are expressed as log10 RNA copy numbers per gram of sample.Back to article page
