<p>Leptospirosis is a globally distributed infectious disease that affects both animals and humans. While the infection is endemic in tropical regions, its incidence seems to increase in temperate regions. The serological diagnostic test used in routine to detect antibodies against the bacteria responsible for the disease performs better when local variants are used. In Austria, however, no locally circulating strain has been available to date. A new study, published in the latest issue of <em>Scientific Reports</em>, has now been able to close this research gap. </p>
