[Occurrance of antibodies against Leptospira in horses in Middle Germany].

The research explores the presence of antibodies against the bacteria Leptospira in horses in Middle Germany. The study found a significant number of horses carrying these antibodies without showing any clinical symptoms, suggesting potential infection.

Study Objective and Methodology

• The purpose of this research was to identify antibodies and potential risk factors for Leptospira infection in horses in Middle Germany.
• This study retrospectively examined serum samples from 314 horses using a microscopic agglutination test, a laboratory technique used to detect the presence of antibodies against specific bacteria.
• The antibodies for eight different Leptospira serovars – distinct variations within a species of bacteria – were investigated.

Findings and Observations

• Overall, 17.2% of the horses tested positive for one or more of the serovars analyzed.
• The most prevalent serovar detected was lcterohaemorrhagiae, found in 11.1% of the horses, followed by Bratislava (found in 9.6% of horses) and Grippotyphosa (1.9%).
• Notably, mares showed a significantly higher occurrence of antibodies than geldings or stallions.
• The likelihood of antibody presence varied with the horse’s use. Horses used for breeding have a significantly lower risk than horses used in sports or leisure activity.
• The prevalence of antibody presence was higher in the summer season than in other seasons of the year.

Other Significant Findings

• The study didn’t find a significant correlation between breed, husbandry conditions, and age on antibody occurrence.
• No major differences were observed in clinical chemical parameters between horses with positive or negative Leptospira antibody results, suggesting that horses can be infected with Leptospira without showing clinical symptoms.
