title: Swarming characteristics of Proteus mirabilis under anaerobic and aerobic conditions.
abstract: Nutrients have a pronounced effect on the growth and swarming behaviour of Proteus mirabilis 7002. Iron, zinc, amino acids, and dioxygen are important for rapid growth and normal swarming. Anaerobically grown cultures of P. mirabilis 7002 were unable to swarm on anaerobically maintained rich nutrient agar. Upon exposure to aerobic conditions, P. mirabilis 7002 resumed swarming behaviour. Scanning electron microscopy was used to demonstrate the presence of community organization and mature rafts during normal swarming. These results support the importance of dioxygen and redox status in cell differentiation.
