sp. nov., a hippurate-positive species isolated from poultry Free

Abstract

Three strains of an unusual hippurate-positive species were isolated at 37 °C from caecal contents of broiler chickens and a turkey. All strains were initially identified as by means of genus-specific PCR, but none was further identified using specific PCRs for known thermophilic species. Phylogenetic analyses based on 16S rRNA, and gene sequences revealed that these strains formed a robust clade distinct from other species. Amplified fragment length polymorphism analysis and whole-cell protein electrophoresis were subsequently carried out and confirmed the divergence between the avian strains and other taxa. These data indicate that the unidentified strains belong to a novel taxon which could be distinguished from other campylobacters through its phenotypic and genotypic characteristics. The name sp. nov., is proposed for the novel species, with the type strain 86/06 (=LMG 24591 =CCUG 56292).
