title: RFLP-PCR analysis of the aroA gene as a taxonomic tool for the genus Aeromonas.
abstract: The aroA gene has been identified as a target in screening for the presence of most Aeromonas species so far described by PCR. Synthetic oligonucleotide primers of 24 and 25 nucleotides were used by PCR assay to amplify a sequence of the aroA gene, which encodes 3-phosphoshikimate-1-carboxyvinyltransferase, a key enzyme of aromatic amino acids and folate biosynthetic pathway. A 1236-bp DNA fragment, representing most of the aroA gene, according to the nucleotide sequence of A. salmonicida, was amplified from all Aeromonas species tested, which represented most of the 14 hybridization groups. HaeII digestion of the 1236-bp fragment generated a restriction fragment length polymorphisms which could be used as a powerful tool for identification of aeromonads to the genus level.
