Abstract

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-3023T (=LMG 24377T =CCUG 38513T).
