    Abstract

    Newcastle disease virus (NDV) strains isolated from ostriches have been genotyped for the first time by partial sequencing of the F gene to determine the epidemiologic role that this species can play within ND outbreaks. Fifteen additional NDV strains, mostly isolated from chickens but also from pigeons and penguins, were also included in the study to determine genetic relationships with ostriches NDV isolates. High genetic diversity was demonstrated in ostrich NDV isolates, as the 10 isolates were grouped in four distinct NDV genotypes. In agreement with the results obtained when chicken isolates have been molecularly characterized, the predominant genotype in ostriches was the genotype VII. More interestingly, evidences of recombination between genotype II and VII were observed in one ostrich isolate and in two further chicken isolates. Therefore, it seems that ostriches may play a relevant role in the ecology and epidemiology of ND particularly in those regions where they have an increasing farming importance as minor poultry species. © 2010 Elsevier B.V.
