Recovery of velogenic Newcastle disease virus from dead and healthy free-roaming birds in Nigeria.
Fourteen Newcastle disease virus isolates were recovered, 10 from dead birds (nine chickens and one guinea fowl) and four from apparently healthy, free-roaming birds (one chicken, two ducks and one pigeon) in Nigeria. The pathogenicity indices showed all the isolates to be velogenic.
