A polymerase chain reaction (PCR) assay was developed for the identifi
cation of the three species of Arcobacter which have been recovered fr
om clinically ill or healthy humans and/or livestock, namely Arcobacte
r butzleri, Arcobacter skirrowii and Arcobacter cryaerophilus. The ass
ay utilizes primers targeted to the genes encoding 16S rRNA of Arcobac
ter spp. The assay reduces the amount of time required to positively i
dentify strains of Arcobacter.
