Fig. 59 MYXOBACTERIAL FRUITING BODIES B: THE MYXOBACTERIAL SWARM (11, 12, 16) 111 the vegetative stage also, myxobacteria give the impression of a degree of organisation far beyond that of other bacteria. The swarm moves outwards from the centre of germination in a regular fashion, following the hues of physical stress in the substrate. It concentrates in chosen areas, converging towards the incipient fruiting body, and piling up, the bacteria crawling over each other, to encyst in an elevated mass. The appearance of ordered purpose is most remarkable in so lowly an organism. C; THE SWARM OF PROTEUS (9, 12, 13, 15) Some degree of cell-specialisation and organisation in the swarm of Proteus is indicated by Klieneberger-Nobel (1947) and other workers. It is suggested that the swarm commences its activity when an initial generation of large cells has produced a sufficient concentration oi metabolites to provide the energy for swarming. The swarm cells are filamentous. They move out rapidly over the substrate until their reserve oi energy is exhausted, and then f rest until it becomes possible to repeat the process.
