[West Nile virus infection of agricultural animals in the Astrakhan region, as evidenced by the 2001-2004 serological surveys].
Abstract: Sera sampled from 2,884 farming animals in the Astrakhan region in 2001 to 2004 were investigated by the hemagglutination inhibition test (HIT) in order to indicate specific antibodies to West Nile virus (WNV). HIT-positive samples were investigated by the neutralization test (NT). WNV antibodies were detected in all the examined species of animals: horses (the proportion of positive tests throughout the observation averaged 9.8%; the agreement with NT results was 94.1%), cattle (6,4 and 72.%), camels (5.2 and 41.7%), pigs (3.1 and 75%), and sheep (2.2 and 57.1). Relationships between the environmental features of WNV in different natural zones, the infection rate, and the conditions of keeping farming animals in the Astrakhan region are analyzed.

The research organization conducted a study from 2001 to 2004, analyzing sera samples from 2,884 farming animals in the Astrakhan region to identify the presence of West Nile Virus (WNV) antibodies. They found that all examined species had WNV antibodies, indicating WNV infections among these animals in the region.
Methodology and Findings
- The study involved testing sera samples from 2,884 agricultural animals in the Astrakhan region collected from 2001 to 2004.
- The initial testing method used was the Hemagglutination Inhibition Test (HIT), used to indicate the presence of specific antibodies to the West Nile Virus.
- Samples that tested positive with the HIT were then checked by the Neutralization Test (NT).
- The research revealed the presence of WNV antibodies in all the animal species tested. These species included horses, cattle, camels, pigs, and sheep.
- The proportion of positive tests across the entire study was average, with horses showing the highest incidence at 9.8%, followed by cattle at 6.4%, camels at 5.2%, pigs at 3.1%, and sheep at 2.2%.
- The results between the HIT and NT largely agreed, with the highest concurrence in horses at 94.1%.
Interpretation of Results
- The detection of WNV antibodies across the various agricultural animal species indicates a presence of the WNV infection amongst these animals across the Astrakhan region.
- The percentage of each species that tested positive indicates the relative prevalence of the disease among them. The highest was seen in horses, which suggests that they may be the most vulnerable to this infection.
- The overall positive test results indicate a widespread presence of the virus in most farming animals in the region during the time period observed.
- The differences in concurrence between HIT and NT results also shed light on the relative accuracy of these testing methods.
Analysis of Environmental factors
- The study also examined the environmental features of WNV in different natural zones, the infection rate, and the conditions of farming animals in the Astrakhan region.
- Understanding the environmental factors that contribute to the spread of WNV can help inform prevention strategies and potentially lessen the impact of future outbreaks.
- Further investigation and analysis of these factors are necessary to understand and combat WNV transmission in agricultural settings.
