“…It is also plausible that zoonotic enteric bacteria and other pathogens can spread and circulate through wildlife across the Southern Ocean. C. lari, the most abundant Campylobacter species recovered at all four sites, has been reported previously in Southern Ocean penguins, gulls, skuas and seals (Bonnedahl et al, 2005;García-Peña et al, 2017Leotta et al, 2006). The widespread distribution of C. lari among host species and localities and its high genetic diversity suggest that it has long been circulating in the region.…”

“…lari has been detected in penguins belonging to Pygoscelis adeliae and Pygoscelis papua, and Campylobacter lari subsp. concheus in Pygoscelis adeliae and Pygoscelis antarcticus [ 28 ]. Campylobacter has also been found in wild birds living in the wild and housed in rescue centres [ 16 , 17 , 29 , 30 ].…”

Climate change, excessive exploitation of agricultural land which reduces natural habitats, wildlife shooting, and the use of pesticides all cause difficulties for wildlife, with considerable numbers of animals being brought to wildlife rescue centres. Although the efforts of staff involved in wildlife management at these centres usually focus on therapeutic treatments to reintroduce them into the wild, the monitoring of pathogens that may be transmitted to humans is of relevance. Campylobacter (C.) jejuni and C. coli are frequently carried by animals without inducing clinical signs and are responsible for enteric disorders and more rarely extra-intestinal disease in humans. Farm species and poultry, in particular, are the main reservoirs of C. jejuni and C. coli, but wild animals may also be carriers. The aim of this paper was to investigate the presence of C. jejuni and C. coli in wild birds housed at a wildlife rescue centre and to evaluate the sensitivity of the detected strains to antibiotics. Campylobacter was found in 52 out of 209 (24.88%) birds from 33 different species. C. jejuni was more prevalent, while C. coli was only detected in three Long-eared Owls (Asio otus). The incidence of the infection was particularly high (72.22%) among omnivorous species. Infection rates were higher in birds housed indoors (57.14%) than outdoors (31.74%). Moreover, Campylobacter was not detected in species whose mean temperature body is below 40 °C or higher than 42.2 °C. The most common antibiotic resistance in the tested strains was against trimethoprim/sulfamethoxazole, ciprofloxacin and enrofloxacin. In addition, multi-drug resistance was also found. The results highlight the need to increase biosecurity measures at rescue centres so as to reduce health-related risks to workers involved in wildlife management.

“…We isolated Campylobacter spp. from apparently healthy birds, as was done in previous studies [ 18 , 40 ]. While the absence of overt signs of disease suggests commensal colonization rather than infection, clinical signs are rarely observed even in birds that mount an immune response to infection [ 41 – 43 ], and mild symptoms or opportunistic infections cannot be ruled out.…”

“…[ 11 – 13 ]). At least five species of Campylobacter have been found in the Antarctic and the surrounding sub-Antarctic: Campylobacter insulaenigrae [ 14 ], Campylobacter jejuni [ 15 , 16 ], Campylobacter lari [ 14 , 17 , 18 ], Campylobacter subantarcticus [ 19 ] and Campylobacter volucris [ 18 ]. In addition, at least one unidentified C. lari -like bacterium has been reported [ 20 ].…”

Characterization of Campylobacter spp. isolated from wild birds in the Antarctic and Sub-Antarctic

A lack of knowledge of naturally occurring pathogens is limiting our ability to use the Antarctic to study the impact human-mediated introduction of infectious microorganisms have on this relatively uncontaminated environment. As no large-scale coordinated effort to remedy this lack of knowledge has taken place, we rely on smaller targeted efforts to both study present microorganisms and monitor the environment for introductions. In one such effort, we isolated Campylobacter species from fecal samples collected from wild birds in the Antarctic Peninsula and the sub-Antarctic island of South Georgia. Indeed, in South Georgia, we found Campylobacter lari and the closely related Campylobacter peloridis, but also distantly related human-associated multilocus sequence types of Campylobacter jejuni. In contrast, in the Antarctic Peninsula, we found C. lari and two closely related species, Campylobacter subantarcticus and Campylobacter volucris, but no signs of human introduction. In fact, our finding of human-associated sequence types of C. jejuni in South Georgia, but not in the Antarctic Peninsula, suggests that efforts to limit the spread of infectious microorganisms to the Antarctic have so far been successful in preventing the introduction of C. jejuni. However, we do not know how it came to South Georgia and whether the same mode of introduction could spread it from there to the Antarctic Peninsula.
