Prevalence of Borrelia burgdorferi sensu latu in rodents from two areas with varying wild ungulate densities in Southern Sweden
On a global scale, zoonotic vector-borne diseases pose an increasing threat towards human health. In Europe, the haemotophagous ectoparasite sheep tick (Ixodes ricinus) acts as a pathogen vector for diseases like tick-borne encephalitis and Lyme disease with increasing annual incidences during the l...
