Continuing prevalence of African horse sickness in Nigeria.

The research article focuses on the ongoing prevalence of African Horse Sickness in Nigeria, which was confirmed using blood samples from various horse breeds and donkeys tested through an ELISA process.

Research Methodology and Sampling

• The researchers gathered equine sera or blood samples from ten different regions across Nigeria. The regions were chosen to provide a comprehensive overview of the presence of African Horse Sickness across all geographical locations in Nigeria.
• The samples were taken from both indigenous and locally cross-bred horses, imported, exotic horses, and African donkeys. This diverse sample pool was chosen to generate a broad understanding of the disease’s prevalence across different equine species in Nigeria.

Testing Procedure

• The blood samples were then tested for antibodies against African horse sickness viruses (AHSV) using a competitive enzyme-linked immunosorbent assay (ELISA). ELISA is a common laboratory technique used to measure the concentration of substances (in this case, antibodies) in biological liquids (like equine sera) which helps in disease detection.
• A high percentage (79.8%) of the tested samples were found to contain AHSV antibodies. The presence of these antibodies suggests that the equines were infected with the African horse sickness virus at some point, as antibodies are the immune system’s response to an infection.

Conclusion

• The high percentage of positive results signifies a widespread prevalence of African Horse Sickness, reinforcing the notion that the disease is still rampant in Nigeria. The research does not provide a direct reason for the continued prevalence, but the wide geographical spread provides a compelling argument for further investigation and intervention strategies to control and prevent the spread of this disease.
