Complete coding genome sequence of putative novel bluetongue virus serotype 27

Area of Science:

• Veterinary Virology
• Genomics
• Arthropod-borne Viruses

Background:

• Bluetongue virus (BTV) is a significant re-emerging pathogen affecting livestock globally.
• The emergence of novel BTV serotypes poses a continuous threat to animal health and international trade.
• Previous BTV serotypes (BTV-25, BTV-26) were recently identified in Europe and the Middle East.

Purpose of the Study:

• To report the complete coding genome sequence of a novel BTV serotype.
• To characterize the genetic relationship of this new BTV serotype to known BTV strains.

Main Methods:

• Whole-genome sequencing of the novel BTV isolate.
• Comparative sequence analysis using bioinformatics tools.
• Phylogenetic analysis to determine evolutionary relationships.

Main Results:

• The complete coding genome sequence of a novel BTV serotype, designated putative BTV-27, was determined.
• The novel BTV isolate was detected in goats in Corsica, France, in 2014.
• Sequence analysis revealed the closest relationship between the novel BTV serotype and BTV-25 and BTV-26.

Conclusions:

• The discovery of this novel BTV serotype highlights the ongoing evolution and geographic spread of BTV.
• Understanding the genetic makeup of new BTV strains is crucial for disease surveillance and control strategies.
• Continued genomic surveillance is essential to monitor BTV diversity and emergence in animal populations.
