野禽新城疫病毒F和HN基因的遗传变异趋势
Hereditary Variation and Evolution of F and HN Genes of Newcastle Disease Virus Isolated from Wildfowl
摘要
Abstract
Newcastle disease virus carried by wildfowl is the important reason and potential source which caused Newcastle disease in poultry.Based on 44 wildfowls' (including wild duck, parrot, pigeon, swan ,mandarin duck, wild goose, turkey, etc.) NDV from genbank and the pigeon NDV (PB9601) and the penguin NDV(QE01) cloned and sequenced by our laboratory ,the F gene cleavage site sequence, genotype and the hereditary variation of the deduced amino acids of HN and F gene were analyzed.The results showed the most NDV isolates genotype belonged to Ⅶ and Ⅵ and the others existed different genotypes (I, II, V, IX).Through the hereditary variation analysis of F gene,the isolates had obvious regional and genus traits among the same species or the same regions; most of the isolated strains had farther genetic distance with LaSota, V4, B1, TEX-48.The similar results can be obtained through the genetic evolution of relations of HN genes.关键词
