Virus titration of nasal washes of ferrets or pigs and oropharyngeal swabs of ducks or chickens infected with A/AB/Kor/CN5/09 (H6N5) virus
| Animal | Group | Mean virus titer (log10 EID50/ml) ± SD (no. of animals shedding virus/no. tested) at indicated day postinfectiona |

Virus titers were determined in eggs. Data are titers of positive samples (≥0.75 log10 EID50/ml). <, titer was below the limit of detection (<0.75 log10 EID50/ml).
