Mimicking MDAs with PTAs in SPF chickens and the response to vaccination and challenge. After transferring antibodies into SPF chickens, chickens were vaccinated one day later and challenged 28 d after vaccination. Seroconversion after vaccination (a), viral titers in oropharyngeal swabs after challenge (b) and seroconversion after challenge (c) are shown in Fig. 2. Superscripts a-c denote differences among each group at the same time point. The symbol (*) denotes differences among groups at the same time point. P < 0.05 was considered significant
