In examination of colonial birds in the Volga delta in the Astrakhan region (188 bioassays from 229 birds) and in the Komandorskie Islands of the Kamchatka region (244 bioassays from 208 birds) in 1974, 15 strains of Newcastle disease virus (NDV) were isolated (8 strains from 7 birds and 7 strains from 12 birds, respectively). The strains were isolated from Egretta alba and Ardea cinerea, and Phalacracorax carbo in the Astrakhan region and from Lunda cirrhata and Uria aalge in the Komandorskie Islands. The isolates were obtained from tracheal and cloacal washings and from pools of viscera. These data are the first evidence of the existence of Newcastle disease virus foci in the USSR.
