This research article presents the full genetic sequences of four strains of African Horse Sickness Virus that are used in a commercial vaccine for the disease in South Africa.

Overview of the Research

The main objective of this study was to sequence the genomes of the four virus strains used in a tetravalent (designed to protect against four different strains) live attenuated (weakened) vaccine for African Horse Sickness. The strains were selected through plaque assay, a method that involves isolating and growing individual viruses in cells.

Methodology of the Study

  • The researchers isolated four different strains of the African Horse Sickness Virus, which are included in a South African commercially produced vaccine against the disease.
  • These strains were plaque-selected, implying they were singled out in lab culture plates for their ability to infect cells and form visible patches or plaques. This procedure helps in isolating individual strains from a mixture.
  • After isolation, the genetic material of the viruses, their genetic blueprint was completely sequenced. This sequencing helps in understanding the genetic composition of these virus strains, including the genes that cause disease and those that evoke immune response.
  • The complete genome sequences serve as references for future research, to understand the genetic diversity of the virus and to develop better, possibly more specific, vaccines against each strain.

Significance of the Research

  • Providing the complete genome sequence of the four African Horse Sickness Virus strains can aid in understanding the diseases they cause.
  • The information is valuable for the development of diagnostic tests and efficient vaccines.
  • The sequenced genomes can act as valued references for future epidemiology studies, virus tracking and understanding the genetic diversity of the virus.

This research contributes to the fields of virology, epidemiology and vaccine development by providing a detailed understanding of the genetic composition of the four African Horse Sickness Virus strains. Understanding these genomes helps in tracking the spread of these virus strains, predicting and controlling outbreaks and improving current vaccinations.
