title: Ehrlichia-infected ticks on migrating birds.
abstract: During the spring of 1996, an estimated 581,395 Ehrlichia-infected ticks were imported into Sweden by migrating birds. Ehrlichia gene sequences found in ticks collected from these migrating birds were identical to those of granulocytic ehrlichiosis found in domestic animals and humans in Sweden. These findings support the idea that birds may play a role in dispersing Ehrlichia.
