Lyme disease is caused by a bacterium that can be transmitted by tick species in the genus, Ixodes. There are dozens of Ixodes species specializing on a wide variety of sometimes overlapping hosts. Ixodes uriae is a tick parasite of many sea birds and travels the globe as the sea birds migrate. Ixodes uriae can be found on king penguins in the southern Indian ocean and is likely responsible for transmitting the Lyme disease bacterium, Borrelia burgdorferi to the penguins.
