Abstract
Avian paramyxoviruses isolated from turkeys in 1981 and 1982 were shown by haemagglutination inhibition tests and structural polypeptide analysis to be similar viruses of PMV‐3 serotype but more closely related to PMV‐3/turkey/Wisconsin/68 than to PMV‐3/parakeet/Netherlands/ 449/75 or PMV‐3/parakeet/England/l‐83/82.
