Abstract: Migratory shorebirds use, among many, the East Atlantic Flyway that links breeding areas as north as Tundra habitats to aquatic wintering grounds in West Africa. As a consequence, they are potentially important in the spread of global zoonotic diseases transmitted by ticks, such as Lyme borreliosis and tularemia—two diseases previously detected in Portugal. In this study, we looked at the infection status of seven populations of shorebirds during their migration, breeding, or wintering in the Portuguese wetlands to access if they carry these pathogens and to discuss their potential risk in the Portuguese wetlands. A total of 212 migratory shorebirds captured in the Tagus and Sado estuaries; key staging and wintering sites in this flyway and important breeding areas for some species were analyzed for the presence of Borrelia burgdorferi sensu lato and Francisella tularensis. In the present study, B. garinii was identified in seven (3%) specimens (five black-tailed godwits Limosa limosa, one common redshank Tringa totanus, and one little stint Calidris minuta), whereas F. tularensis subsp. holarctica was identified in one (0.4%) little stint. To our knowledge, this is the first evidence that shorebirds that migrate through or winter in Portugal transport these pathogens, potentially contributing for their introduction along the flyway, including the Mediterranean region.
