Figure 1. Oropharyngeal shedding of influenza A(H9N2) virus isolate A/environment/Bangladesh/9306/2010 (Env/9306) by pet birds and chickens, Bangladesh. Measurement of donor and contact bird virus shedding is based on the inoculation date of donors; donor and contact birds were kept in the same cage or enclosed environment. A) Donor finches (n = 5), B) parakeets (n = 5), or C) chickens (n = 6; red lines) were inoculated with 105 log1050% egg infectious doses (EID50) units of Env/9306 and paired with naive birds of the same species (n = 4 or 5; black lines) in the same cage. Birds were swabbed every 2 dpi and virus titer (log10 EID50/mL) was determined in eggs. Individual shedding curves for each animal are provided.
