Fig. 3From: Virulence of three European highly pathogenic H7N1 and H7N7 avian influenza viruses in Pekin and Muscovy ducksVirus excretion in the oropharyngeal and cloacal swabs in Muscovy and Pekin ducks challenged with H7N1-It99 by intrachoanal or intramuscular routes. Virus excretion in oropharyngeal and cloacal swabs at 2 (a-b), 4 (c-d) and 7 (e-f) days post inoculation using RT-qPCR expressed by equivalent Log10 PFU/mL. All results are expressed as average and standard deviation (mean ± SD) per group at indicated time points post infection. The viruses were not detected in swabs collected at 10 dpi (data not shown). Statistical significance shown in asterisks indicate P values < 0.05. For clarity, results of H7N1-It99 IC-inoculated ducks (group 3) was presented in Figure 3 again for comparisonBack to article page
