Serological evidence of equine arteritis virus in donkeys in South Africa.

This research paper investigates and reports the first recognized instance of donkeys being exposed to the equine arteritis virus in South Africa.

Research Methodology

• The researchers collected a total of 734 serum samples from donkeys across several regions of South Africa.
• The time period for the collection was between the years 1989 and 1992.
• The presence of antibodies against the equine arteritis virus was detected using a microneutralization test – a standard diagnostic technique for detecting and measuring antibodies against a virus.

Findings

• Out of the 734 samples, approximately 17% of serum samples tested were found to be positive for the virus.
• The distribution of animals testing positive not only varied across different regions but showed a notable absence of positive cases in the western Cape Province and the Transvaal Highveld.
• However, in certain regions like the northern Transvaal, approximately 30% of the tested samples were found to be positive.

Conclusions

• The nationwide distribution of seropositive donkeys indicates that the equine arteritis virus has been present in South Africa for quite some time.
• This study provided the first serological evidence of exposure of donkeys to the equine arteritis virus in South Africa.
• The findings of this research paper may guide future strategies for disease control and prevention in the equine population.
