<p>Ticks are vectors for a larger number of viruses and bacteria than all other arthropod taxa, including mosquitoes. In Europe is it foremost Borrelia spirochetes and the Flavivirus Tick-borne Encephalitis virus that cause disease in humans. In this study, the tick species <em>Ixodes uriae</em> has been studied. <em>I.</em><em> uriae</em> have a circumpolar distribution in both hemisphere and can be found both in Arctic and Antarctica. I collected ticks from Magellanic penguins in south Chile and analyzed them to see if they carry <em>Borrelia</em> spirochetes or Flavivirus. Totally were 218 ticks collected from 165 controlled penguins. All ticks were collected from adult penguins and the parasitizing ticks were all found in the auditory meatus which is a new phenomena compared to earlier studies. Both <em>Borrelia</em> spirochetes and Flavivirus were found in the collected ticks using PCR techniques. This is an interesting result since not much research has been performed in this geographical area before. Until date there is only one species of <em>Borrelia</em> (<em>Borrelia</em> <em>garinii</em>) found in <em>I.</em><em> uriae</em> on the southern hemisphere and new Flavivirus is regularly found around the world. Unfortunately we have not been able to determine species of the <em>Borrelia </em>spirochetes or Flavivirus so far but this work will be continued. <strong></strong></p>
