Viral titers from oropharyngeal swabs and trachea tissue from inoculated chickens in both the long-term and short-term antibiotic treatment trials. Viral titers in oropharyngeal swabs and tracheal tissues of H9N2-infected chickens in the long-term antibiotic treatment trial (A and B) and short-term antibiotic treatment trial (C and D). Ratio of positive samples to the number of all tested samples is shown above each group. Dashed black lines indicate the lower limits of detection (*P < 0.05, Kruskal–Wallis and Dunn’s tests)
