a
NDV was isolated from the oropharyngeal swab samples (
&
) or from both oropharyngeal and cloacal swab samples from the same bird (
*
). NDV isolates without any symbolic notation were isolated from cloacal swabs only.
b
Mean death time in 10 d-old SPF embryonated chicken eggs (hours) (< 60, velogen; 60–90, mesogen; >90, lentogen).
c
Intracerebral pathogenicity index in day-old chickens (< 0.7, lentogen; 0.7–1.4, mesogen; 1.4–2.0, velogen).
d
Amino acids 112–117.
