“…Class II of ND viruses are a group of viruses most virulent and avirulent viruses with some genotypes I-IV found prior to 1960 with the genome size of 15186, while genotype V-VIII, a new strain that was isolated after 1960 with a genome size of 15192 nt. genotype VII and VIII are new genotypes found after 1980 that caused a pandemic in Europe, the Far East and South Africa (Czegledi et al, 2006;Herczeg et al, 1999;Ke et al, 2001;Lomniczi et al, 1998;Abolnik et al, 2004;Liu et al, 2007). The results of our study showed that the ND virus used in this study was six isolates belonging to genotype VII, one virus was genotype 1 and other virus are genotype VI.…”

Newcastle disease (ND) is a very contagious disease in chickens and turkeys and one of the most important diseases of poultry in the world. The infection causes sudden death with high mortality. In Indonesia, Newcastle disease in recent years showed symptoms slightly different from previous symptoms of this disease. NDV infection of genotipe VII has been reported to cause this outbreak in several commercial poultry farms in Indonesia. This study aimed to isolate and identify the recent ND virus and determine group of genotype of ND in Indonesia for the development of seed of ND vaccines expected to be more effective in the control of Newcastle disease in the field. The method used in this study includes the collection of samples from the field, ND virus isolation, RT-PCR and DNA sequencing of the F and HN genes of ND viruses. Our result showed that six isolates belong to genotype VII of ND viruses, one isolate belong to genotype VI and the other isolate belong to genotype I. The prediction of pathotypes of amino acids sequence on F gene of NDV indicated that seven isolates have motif R-R-R-K-R and R-R-Q-K-R which is a marker for pathotype for velogenic of ND viruses. The cleavage site of amino acid sequences from one isolate (RIVS isolate) has G-K-Q-G-R-L which is lentogenic pathotype of NDV. This study indicated that genotype VII viruses were predominant virus circulating in the field and we suggested the update of master seed vaccine of ND in Indonesia.

“…Kr-owl/6/05 and the Kr-owl/7/ 05 were placed in the genotype VII and showed the highest degree of similarity to strains of NDV (Ch-501/02, ZJ-1/00, Kr-005/00, and KBNP-4152) belonging to subgenotype d of the genotype VII (VIId). This indicates that these Korean owl isolates belong, genetically, to the VIId group, which is prevalent in poultry in eastern Asia, including Korea, Japan, China, and, in more recent years, Taiwan (Ke et al, 2001;Yu et al, 2001;Mase et al, 2002;Lee et al, 2004;Zou et al, 2005). Interestingly, the owl isolates Krowl/6/05 and the Kr-owl/7/05 showed the highest nucleotide similarities (99.5% over 389 nucleotides) to Korean isolates Kr-021/04, which was isolated from a layer chicken in December 2004 (Cho et al, 2007).…”

“…Most recent Korean isolates (since 2000) belong to sublineage d of genotype VII (VIId) (Lee et al, 2004). The prevalence of VIId in Korea is similar to that in neighboring countries, including China (Liang et al, 2002;Liu et al, 2003;Zou et al, 2005), Japan (Mase et al, 2002), and Taiwan (Kou et al, 1999;Yang et al, 1999;Ke et al, 2001;Tsai et al, 2004). Newcastle disease virus strains can be classified into three pathotypes (lentogenic, mesogenic, and velogenic) on the basis of in vivo pathogenicity test parameters such as the mean death time (MDT) in specific pathogen-free (SPF) chicken embryos and the intracerebral pathogenicity index (ICPI) in day-old SPF chickens.…”

“…All isolates from chickens were classified into genotype VII, the predominant genotype responsible for most Newcastle disease outbreaks in the East Asian countries, including Japan [6,[10][11][12][21][22][23]. Among the isolates from chickens, those collected in 2001 (JP/Nagano/01 and JP/ Miyagi/02) were clustered with isolates from 2000 to mid-2001, suggesting that they were derived from a common origin.…”

“…The phylogenetic analysis of NDV reported by several groups of the researchers revealed that genotype VII has been predominant in East Asian countries, including Korea, Taiwan and China, since the 1980s [6,[10][11][12][21][22][23]. This genotype has also been the predominant pathogen in Japan, mainly in chickens, since 1985 [15].…”

ABSTRACT. Seventeen isolates of Newcastle disease virus (NDV) were obtained from various prefectures in Japan during the years 2001-2007 and were genotypically analyzed by the reverse transcriptase-polymerase chain reaction (RT-PCR) method coupled with direct sequencing. These NDV isolates were classified into three genetic groups that had been reported previously, namely, genotypes I, VI and VII. The isolate from an aigamo duck was classified into genotype I with isolates mainly from waterfowl. All isolates from pigeons were classified into genotype VI, the predominant genotype responsible for most Newcastle disease outbreaks in pigeons. The isolate from a pet bird was classified into genotype VI, distinct from the remaining viruses in genotype VI. All isolates from chickens were classified into genotype VII, the predominant genotype responsible for most Newcastle disease outbreaks in the East Asian countries. Among the isolates from chickens, isolates after 2002 were genetically most closely related with isolates in Korea. The single isolate from a wild cormorant was also classified into genotype VII, although it was different from the recent NDV epidemic strain in Japan.KEY WORDS: epidemiology, genotype, Newcastle disease virus.
