Mean AIV titers by quantitative real-time RT-PCR for each swab construction type by day post inoculation and transport media: a) brain heart infusion (BHI), b) phosphate buffered saline (PBS). Statistical significance (pā€‰ā‰¤ā€‰0.05) in differences among the amount of virus recovered by swab construction type for each day post inoculation is indicated by different letters above the bars. Error bars represent standard deviation.
