The genome sequence of a reassortant bluetongue virus serotype 3 from India.

ABSTRACT: All 10 genome segments (Seg-1 to 10-a total of 19,188 bp) were sequenced from a strain of bluetongue virus serotype 3 (BTV-3) from India (strain IND2003/08). Sequence comparisons showed that nine of the genome segments from this virus group with other eastern topotype strains. Genome Seg-2 and Seg-6 group with eastern BTV-3 strains from Japan. However, Seg-5 (the NS1 gene) from IND2003/08 belongs to a western lineage, demonstrating that IND2003/08 is a reassortant between eastern and western topotype bluetongue viruses. This confirms that western BTV strains have been imported and are circulating within the subcontinent.

Genome sequence of a reassortant strain of bluetongue virus serotype 23 from western India.

Project description:The full genome sequence (19,177 bp) of an Indian strain (IND1988/02) of bluetongue virus (BTV) serotype 23 was determined. This virus was isolated from a sheep that had been killed during a severe bluetongue outbreak that occurred in Rahuri, Maharashtra State, western India, in 1988. Phylogenetic analyses of these data demonstrate that most of the genome segments from IND1988/02 belong to the major "eastern" BTV topotype. However, genome segment 5 belongs to the major "western" BTV topotype, demonstrating that IND1988/02 is a reassortant. This may help to explain the increased virulence that was seen during this outbreak in 1988. Genome segment 5 of IND1988/02 shows >99% sequence identity with some other BTV isolates from India (e.g., BTV-3 IND2003/08), providing further evidence of the existence and circulation of reassortant strains on the subcontinent.

Full-Genome Sequence Analysis of a Reassortant Strain of Bluetongue virus Serotype 16 from Southern India.

Project description:The complete genome sequence of a reassortant field strain (IND2014/01) of Bluetongue virus (BTV) serotype 16, isolated from sheep from southern India in 2014, was sequenced. The total genome size was 19,186 bp. Sequence comparisons of all genome segments, except segment 5 (Seg-5), showed that IND2014/01 belonged to the major eastern topotype of BTV.

Full genome sequence of bluetongue virus serotype 1 from India.

Project description:We report the full-genome sequence of an Indian isolate of bluetongue virus serotype 1 (BTV-1), strain IND1992/01. This is the first report of the entire genome sequence (Seg-1 to Seg-10) of an Eastern (e) strain of BTV-1. These sequence data provide a reference for BTV-1e that will help to define the phylogenetic relationships and geographic origins of distinct Indian lineages of BTV-1 as well as their relationships with other BTV strains from around the world. The availability of data for all 10 genome segments of this strain will also help to identify reassortment events involving this and other virus lineages.

Complete genome sequence analysis of a reassortant strain of bluetongue virus serotype 16 from Italy.

Project description:The complete genome sequence of a reassortant field strain of bluetongue virus serotype 16 (BTV-16), isolated from cattle in the Apulia region of Italy in 2002, has been determined by Illumina sequencing. Sequence comparisons of segment 1 (Seg-1) to Seg-10, except Seg-5, show that BTV-16 strain ITL2002 belongs to the major eastern topotype of BTV.

Complete genome sequence of bluetongue virus serotype 16 of goat origin from India.

Project description:In this article, we document the first complete genome sequence of an isolate of bluetongue virus serotype 16 (BTV16) from a goat in India. The virus was isolated from an in-contact goat from an animal farm in Chennai where clinical disease occurs in sheep. The total size of the genome is 19,185 bp. The information provided for full-length sequences of all 10 segments will help in understanding the geographical origin and transmission of the Indian isolate of BTV16 as well as its comparison with global isolates of BTV16 of sheep, cattle, and other host species origins.

Full genome sequence of bluetongue virus serotype 4 from China.

Project description:The complete genomic sequence of a bluetongue virus serotype 4 (BTV-4) strain (strain YTS-4), isolated from sentinel cattle in Yunnan Province, China, is reported here. This work is the first to document the complete genomic sequence of a BTV-4 strain from China. The sequence information will help determine the geographic origin of Chinese BTV-4 and provide data to facilitate future analyses of the genetic diversity and phylogenetic relationships of BTV strains.

Project description:The second complete genome of bluetongue virus serotype 9 (BTV-9) is presented in this report. The sequence analysis points to continued circulation in India of a mixed topotype virus apparently belonging to the BTV-9 serotype, and it raises questions about approaches for serotyping bluetongue viruses.

Complete genome sequence of an isolate of bluetongue virus serotype 2, demonstrating circulation of a Western topotype in southern India.

Project description:Bluetongue virus serotype 2 (IND2003/02) was isolated in Tiruneveli City, Tamil Nadu State, India, and is stored in the Orbivirus Reference Collection at the Institute for Animal Health, Pirbright, United Kingdom. The entire genome of this isolate was sequenced, showing that it is composed of a total of 19,203 bp (all 10 genome segments). This is the first report of the entire genome sequence of a western strain of BTV-2 isolated in India, indicating that this virus has been introduced and is circulating in the region. These data will aid in the development of diagnostics and molecular epidemiology studies of BTV-2 in the subcontinent.
