Tick-borne encephalitis virus (TBEV) infection in horses: clinical and laboratory findings and epidemiological investigations.
Abstract: During a routine examination of 130 horse sera from 13 herds in Thuringia one TBEV antibody positive serum - with a very high titre - could be detected. The horse had been bought from a holding in Bavaria, and was reported to have clinical signs that may have been caused by a TBEV infection. To identify the source of the suspected TBEV infection, ticks from the surroundings of the barn in Thuringia as well as horse sera and ticks from two herds in Bavaria were examined. In the holding in Bavaria, where the horse was kept before, two out of ten horse sera were found to be TBEV antibody positive (20%), in a second herd nearby five out of 15 horse sera were TBEV antibody positive (30%), and in one serum TBEV-RNA could be detected. In addition, at both Bavarian sites, two different TBEV strains were detected in ticks collected in the vicinity of the respective holdings and in the surrounding areas. In contrast, no TBEV-RNA could be found in ticks collected in Thuringia. The suitability of horses as sentinels for the detection of natural TBEV foci supported by subsequent, targeted tick collection as well as the clinical importance of TBEV infection in horses are discussed.

Summary

The study investigates incidences of Tick-Borne Encephalitis Virus (TBEV) in horses, categorizing its clinical symptoms, laboratory findings, as well as carrying out epidemiological investigations to determine potential sources of the virus.
Background and Methods
- The research was initiated after detecting a case of TBEV during a routine examination of 130 horse sera from 13 herds in Thuringia, Germany.
- The horse in question showed signs that suggested TBEV infection and was bought from a holding in Bavaria.
- To identify the source of the TBEV infection, ticks from the horse’s new surroundings in Thuringia and its previous location in Bavaria were examined.
- Horse sera and ticks from two Bavarian herds were also examined.
Findings
- In Bavaria, where the horse was originally kept, TBEV antibodies were found in 20% (2 out of 10) of horse sera.
- In a nearby Bavarian herd, a higher percentage (30%) or 5 out of 15 horse sera were TBEV antibody positive.
- TBEV-RNA was detected in one serum.
- Two different TBEV strains were identified in ticks collected from the vicinity of the Bavarian holdings and the surrounding areas.
- In contrast, no TBEV-RNA was found in ticks collected in Thuringia, the new location of the initially infected horse.
Conclusion and Discussion
- The study contributes to the understanding of TBEV infections in horses, including symptomology and the potential geographic-related prevalence of the disease.
- It posits the potential role of horses as sentinels for the detection of TBEV in natural environments.
- The research also throws light on the importance of considering geographic location as a significant factor in TBEV infection rates, given the diverse results between Thuringia and Bavaria.
