Wildlife are important reservoirs of bacterial pathogens associated with human diseases. Campylobacteriosis is a relevant gastrointestinal disease in humans and is caused principally by Campylobacter jejuni and Campylobacter coli. This review compiles the current knowledge of the potential for wildlife to carry and spread Campylobacter spp. This output contains supplementary files of results of epidemiological wildlife studies.

Collection Method Campylobacter spp. are part of the Campylobacteriaceae family. These bacteria are Gram-negative rods, small (0.2–0.9 μm wide and 0.2–5.0 μm long), spirally curved, and do not form spores. They move in a way that resembles a corkscrew and are chemoorganotrophs and obtain their energy sources from amino acids or tricarboxylic acid cycle intermediates. Campylobacter is the most reported cause of bacterial infectious gastrointestinal disease. However, systematic disease surveillance programs, which include campylobacteriosis, are largely limited to industrialized countries, such as the United States and member states of the European Union, because in non-industrialized countries they are either scarce or have a lower incidence. Campylobacter infections in humans principally cause diarrhea; however, the severe neuropathological disorders Guillain–Barré syndrome (GBS) and Miller Fisher syndrome (MFS), and reactive arthritis have been associated with Campylobacter infections. Campylobacteriosis is the most common disease caused by Campylobacter spp. These bacteria have a worldwide distribution and a wide host variability. Food-producing animals such as cattle, sheep, swine, and poultry commonly harbor Campylobacter spp. in their gastrointestinal tracts and represent an important route through which organisms could enter the food chain. Data from the articles reviewed showed that at least twelve Campylobacter species have been detected in wild animals in 36 countries and the Antarctica Peninsula. Details of the animal species involved are found in Table S1 in the supplementary data. The most commonly detected species was C. jejuni, followed by C. coli and C. lari. However, other species, C. fetus, Campylobacter helveticus, C. upsaliensis, Campylobacter hyointestinalis, Campylobacter sputorum, Campylobacter canadensis, Campylobacter hepaticus, Campylobacter subantarcticus, and Campylobacter volucris have also been sporadically detected in wildlife. Prevalence estimates for reptiles, mammals, and birds species are presented in Table S1, and this includes information for Campylobacter, C. jejuni, C. coli, and C. lari when available. This review has shown that wildlife can act as an important Campylobacter spp. reservoir, with several studies described in birds and mammals, but less in amphibians, reptiles, and fish. Although most Campylobacter studies have been carried out with either humans or domesticated animals, there are a number of studies which describe the potential roles of wildlife and the environment as a source of C. jejuni infection. In fact, not all studies have been related to human outbreaks with wildlife sources using whole-genome multilocus sequence typing (MLST).
