Abstract
Processes and apparatus are provided for selectively culturing motile bacteria such as Salmonella, Camplylobacter, and others. One embodiment entails providing a carrier partly dipping into the liquid nutrient medium but projecting above a surface of the liquid nutrient medium, the carrier containing supported (e.g. gelled) nutrient medium and having an opening below the surface of the liquid nutrient medium for contact between the liquid medium in the culture vessel and the supported medium of the carrier. Migration of the motile bacteria from the liquid into the supported medium during the culture is thereby facilitated. The sample and the nutrient media are incubated to allow growth of any motile bacteria present in the sample in the liquid medium, and to allow migration of the motile bacteria during the culture into the supported medium.
