Virus shedding for chickens inoculated with 6 log10 EID50 of LPAIV-1, LPAIV-2, or HPAIV. Virus titers from oropharyngeal (OP) (blue) and cloacal (CL) (red) swabs were determined by qRT-PCR. Dotted lines indicate the limit of detection for each virus. Asterisks (*) indicate statistically significant difference between OP and CL virus titers (one-way ANOVA with Sidak’s multiple comparisons test; p < 0.05).
