Identification and grouping of Newcastle disease virus strains by restriction site analysis of a region from the F gene

Abstract: A 75% region of the F gene (between nucleotides 334 and 1682) of Newcastle disease virus (NDV) RNA was amplified by reverse transcription polymerase chain reaction (RT-PCR). PCR products were cleaved by three restriction endonucleases and the positions of thirty cleavage sites were mapped in more than 200 NDV strains. Restrictions site analysis established six major groups of NDV isolates and unique fingerprints of vaccine strains. Group I comprised lentogenic strains isolated mainly from waterfowl with some f… Show more

“…The restriction sites of the F gene of each strain are summarized in Table 2. None of the RFLP patterns was the same as those reported previously [4] and they could be grouped into Group VII [8]. Ck/Tw/ 2066/94, isolated before the 1995 outbreak, had the same restriction sites as Ck/Tw/2137/95, Ck/Tw/2164/95 and Ck/ Tw/2174/95.…”

“…The present results indicate that Taiwan isolates belonged to none of the proposed six groups [4], or rather genotype VII based on the restriction site analysis [8]. However, the HinfI and BstOI cutting sites were similar to those of group III NDV strains (AUS/32 and MIY/51).…”

“…Class I viruses are not commonly reported and are found in waterfowl, live bird markets, and domestic poultry (Alexander et al, 1992;Aldous et al, 2003;Seal et al, 2005;Kim et al, 2007). The class II viruses are categorized into genotypes I to IX (Ballagi-Pordany et al, 1996;Lomniczi et al, 1998;Herczeg et al, 1999;Yang et al, 1999;Liu et al, 2003). In Korea, genotype VII first emerged in 1984 and then reemerged in 1995 (Lee et al, 2004).…”
