Characterization of Aeromonas caviae and A. veronii by standardized cellular protein electrophoretic patterns

Aeromonas caviae and A. veronii recovered from clinical and environmental samples were characterized by SDS-PAGE of whole cell proteins. All strains were typable and showed unique banding patterns. A high intra-specific diversity within these two microorganisms was revealed. Separation of the Polish strains from the Hong-Kong isolates was observed. A. caviae and A. veronii were not distinguishable with respect to their ecological origin. However, strains with very similar protein patterns could dominate in a specific habitat.
