The paper analyzes the results of isolation of Newcastle disease virus (NDV) strains from 336 swaps of 31 wild bird species collected in the 2001 summer in the Volga estuary (Astrakhan Region). Twenty-seven NDV strains were isolated from little terns (Sterna albifrons) (n=11; infection rate, 24.4%), great cormorants (Phalacrocorax carbo) (n=6; 11.1%), coots (Fulica atra) (n=8; 6.5%), sandwich terns (Sterna sandvicensis) (n=1; 100%), and common redshanks (Tringa totanus) (n=1; 50.0%). Four strains were sequenced by the 374 n. a. residue fragment from the beginning of the F gene, one of them was by the full F gene, and another (Stemal/Astrakhan/2755/2001) was by the full genome. Nucleotide sequences have allowed the authors to classify corresponding NDV strains as 5b genotype and the analysis of the amino acid sequence of the F-protein cleavage site has shown them to belong to a non-pathogenic group.
