Table 1 Results of pyrosequencing 40 individual plaques picked from nasal wash samples from RD exposed ferrets on the days post exposure indicated, the peak day of virus shedding for these animals.

From: Contact transmission of influenza virus between ferrets imposes a looser bottleneck than respiratory droplet transmission allowing propagation of antiviral resistance
