Identification of Clinical Aeromonas Species by rpoB and gyrB Sequencing and Development of a Multiplex PCR Method for Detection of Aeromonas hydrophila, A. caviae, A. veronii, and A. media

Conventional identification of Aeromonas species based on biochemical methods is challenged by the heterogeneous nature of the species. Here, we present a new multiplex PCR method directed toward the gyrB and rpoB genes that identifies four Aeromonas species, A. hydrophila, A. media, A. veronii, and A. caviae, and we describe the application of this method on a Danish strain collection.
