Pathogen detections and quantifications in nasal swab supernatants and lung tissues of inoculated pigs.

aQualitative results of M gene real-time RT-PCR in nasal swab supernatants collected at 2, 3 and 7 DPI H1N1 and in lung tissues collected at necropsy (+ and − : positive and negative genome detection).bResults of virus titration in nasal swab supernatants. Virus titers are expressed in log TCID50/ml (ni: not isolated; nt: not tested; *: averages calculated with values obtained from successful titrations).cResults of Mhp quantification (expressed in pg DNA/25 mg organ) in lungs at necropsy. SD: standard deviation. N.a.: not applicable.
