Hedgehog home territories are shrinking in urban and rural areas leading to an increase in population densities and the number of animals living in gardens and parks frequented by humans.2 As a consequence, hedgehogs are coming into contact with humans directly when weak animals are found and cared for and indirectly via feces encountered during gardening, posing a risk for transmission of zoonotic agents. Outbreaks of hedgehog-related salmonellosis in humans have been reported in Norway,1 however, minimal information exists about pathogen prevalence in German free-ranging hedgehogs. The goal of this study was to determine if free-ranging hedgehogs in Germany impose a zoonotic risk. The study population included 100 free-ranging hedgehogs which were brought to a veterinary hospital for care and were humanely euthanized or died. Animals were necropsied and organ specimens were screened for infectious pathogens by culture and molecular methods. Listeria spp., Leptospira spp., Escherichia coli, and Salmonella spp. were each identified in approximately 20% of hedgehogs. Chlamydia spp., Yersinia spp., and methicillin-resistant Staphylococcus aureus was identified in lower percentages. Influenza A virus, Francisella tularensis, Coxiella burnetii, and mycobacteria were not detected in any specimen. Our results indicate that hedgehogs in Germany could carry several pathogens with particularly high zoonotic risk to humans.
