Description
Leptospirosis is among the most widespread zoonoses worldwide. Transmission is often via direct or indirect contact with infected rodents which serve as a reservoir. As Leptospira spp. can cause severe infections in humans, it is important to understand the transmission dynamics and identify risk factors for zoonotic infections.
A previous study conducted during 2018 - 2020 in northwestern Germany demonstrated that season, population density, and individual host characteristics significantly influenced Leptospira prevalence in bank voles. The current study aims to compare the prevalence of Leptospira spp. and their genomospecies and sequence types in bank voles from the same trapping sites in 2023 and 2024 with previously published data.
In total, 560 bank voles (Myodes glareolus) were caught in 2023 and 2024 at seven trapping sites at forest plots near Osnabrück. So far six of 161 kidney samples were positive for the lipl32 gene of pathogenic Leptospira spp.. Multilocus sequence typing (glmU, pntA, sucA, tpiA, pfkB, mreA and caiB gene) resulted in the identification of sequence types 24 (L. interrogans), 110 (L. kirschneri) and 197 (L.borgpetersenii). The results of this first subset indicates that in addition to a similar prevalence (3.7% (95% CI: 1.4–7.9)), the occurrence of sequence types remains stable over longer time periods.
These findings underscore the importance of long-term monitoring and further research based on the One Health approach.
