Serological and molecular evidence of Leptospira spp. in martens from Poland

Martens are susceptible hosts for Leptospira spp.. Given their adaptability and overlapping habitats with livestock and humans, they also represent valuable targets for integrated surveillance within the One Health framework. This study provides the first evidence of Leptospira spp. sequence types and serological diversity in martens in Poland, and offers valuable insights into the epidemiology of wildlife leptospirosis.
