First isolation of <i>Campylobacter vicugnae</i> sp. nov. in humans suffering from gastroenteritis.

ABSTRACT: The present study describes the first isolation of a recently described Campylobacter species, Campylobacter vicugnae, in humans. The isolates were recovered by two independent French laboratories in 2020 and 2022 from a man and a woman suffering from gastroenteritis. Biochemical and growth characteristics, and electron microscopy for these two strains indicated that they belong to Campylobacter genus. 16S rDNA and GyrA-based phylogeny, as well as average nucleotide identity and in silico DNA-DNA Hybridization analyses revealed that both strains belong to the Campylobacter vicugnae species. Both isolates possess a complete cytolethal distending toxin (CDT) locus with cdtA, cdtB, and cdtC, and features of CDT activity were demon
