- Faecal bacteria from 49 Gentoo penguins on the Antarctic Peninsula were identified by biochemical methods and sequencing, and tested for antibiotic susceptibility using agar dilution. Of the 42 Enterobacteriaceae isolates found, 39 belonged to the genus Edwardsiella. All isolates were susceptible to the 17 antibiotics tested. This implies that antibiotic selection pressure is a prerequisite to a high prevalence of antibiotic resistance, and in the absence of contact with human activities, antibiotic resistance in Enterobacteriaceae remains undetectable.

- We investigated the potential role of Antarctic tourism in the introduction of human-associated pathogens into Antarctic wildlife. We collected and analyzed 233 fecal samples from eight bird species. The samples were collected at six localities on the Antarctic Peninsula, which often is visited by tourists. Every sample was investigated for pathogens of potential human origin: Campylobacter jejuni, Salmonella spp., and Yersina spp. None of these bacteria was found. Our data suggest that the tourism industry so far has achieved its goal of not introducing pathogens into the Antarctic region. There is, however, an urgent need to further investigate the situation in areas closer to permanent Antarctic settlements.

- Six Gram-stain-negative, spiral-shaped, microaerobic isolates were obtained during a sampling from wild birds in the sub-Antarctic region. Based on initial observations, these isolates were classified as Campylobacter lari-like. The isolates were further characterized by whole-cell protein and amplified fragment length polymorphism (AFLP) analysis, which revealed that they were distinct from C. lari and all other known species of the genus Campylobacter. Here, we present comprehensive phylogenetic, genomic and phenotypic evidence that these isolates represent a novel species within the genus Campylobacter, for which the name Campylobacter subantarcticus sp. nov. is proposed. The type strain is R-3023(T) (=LMG 24377(T) =CCUG 38513(T)).
