The following review aims to summarize the present knowledge on Campylobacter jejuni and other Campylobacter-species in wild birds. The question of whether campylobacters present in wildlife, especially those found in wild birds, play a role in the epidemiology of human campylobacteriosis has been around for more than 30 years (Kapperud and Rosef, 1983; Smibert, 1969). This review will summarize what is currently known and point to the gaps in understanding of these organisms and their interplay with hosts and the environment. Here the focus will mainly be on C. jejuni, as this species has received most attention, but data for Campylobacter coli and Campylobacter lari will also be discussed.
