A study was undertaken to determine the prevalence and diversity of Arcobacter lanthier species in pig and dairy cattle manure that led to the identification of the strains AF1440T, AF1430 and AF1581, respectively. Initially identified as Arcobacter butzleri based on colony morphology and initial PCR-confirmation tests, analyses of 16S rRNA gene sequences of these strains belonged to the genus Arcobacter and were different from all known Arcobacter species. The isolates formed a distinct group within the genus Arcobacter based on their 16S rRNA, gyrB, rpoB, cpn60, gyrA and atp/i}A gene sequences and fatty acid profiles. The unique species status was further supported by physiological properties and DNA-DNA hybridization that allowed phenotypic and genotypic differentiation of strains from other Arcobacter spp. The isolates were found to be oxidase, catalase and esterase positive, and urease negative; they grew well at 30 °C under microaerophilic condition and produced NO2 and Acetoin, respectively. Based on the common origin and various physiological properties it is proposed that the isolates are classified as members of a novel species with the name Arcobacter lanthieri sp. nov., with the strains AF1440, AF1430, AF1581; type strain AF1440T (=LMG 28516T; CCUG 66485T), AF1430 (=LMG 28515; CCUG 66486) and AF1581 (=LMG 28517; CCUG 66487), respectively.
