OP, oropharyngeal swabs; CL, cloacal swabs; –, all of the chickens died at the end of the observation.
a
For statistical purposes, a value of 1.5 was assigned if virus was not detected from the undiluted sample in three embryonated hen's eggs (Kang et al., 2015).
b
Chickens inoculated with virus.
c
Naïve contact chickens housed with those inoculated.
d
No detected.
