Campylobacter lanienae sp. nov., a new species isolated from workers in an abattoir.

Abstract

Campylobacter-like organisms were isolated from the faeces of healthy individuals during a hygiene survey of abattoir workers. The strains, which exhibited characteristics of Campylobacter, being non-glucose-fermenting, oxidase- and catalase-positive, Gram-negative, motile rods, were identified to the genus level by a PCR assay. Nucleotide sequence analysis of the 16S rRNA gene, DNA homology experiments and determination of G + C content demonstrated that they constituted a previously undescribed species, whose nearest phylogenetic neighbours were Campylobacter hyointestinalis subsp. hyointestinalis, Campylobacter fetus and Campylobacter mucosalis. The name Campylobacter lanienae sp. nov. is proposed for this taxon and species-specific PCR primers were evaluated which will find use in the study of its epidemiology, prevalence and pathogenicity.
