Natural communities of marine bacteria, an isolate (FMB-Bf3) from one marine community, and Escherichia coli were examined by video microscopy for the magnitude and uniformity of their speed. Natural communities formed tight microswarms that showed higher speeds (mean = 230 microns s-1) than did E. coli (15 microns s-1) or FMB-Bf3 (mean = 62 microns s-1). Outside the microswarms, the marine bac...
