[Evaluation of 2 culture media for the isolation and enumeration of motile Aeromonas in different kinds of water].

In recent years an increasing incidence of Aeromonas-related cutaneous infections and gastroenteritis has raised a serious public health problem. It appeared therefore timely to define a specific method allowing the rapid isolation and enumeration of the bacteria in their various aquatic habitats. In this line of research we have compared the growth of Aeromonas originating from different aquatic sources and raised on two media, i.e. RS-agar and PXA-agar. Whatever the aquatic system we observed that the PXA-agar medium clearly was better adapted for a quick enumeration of Aeromonas.
