[Study of bacterial motility and rate of movement using a closed circuit television]

Speed and motion patterns of Campylobacter fetus ssp. jejuni, Escherichia coli and Pseudomonas aeruginosa were recorded using a closed circuit television camera attached to a phase contrast microscope. A Sony video analysis system was used to stop frame videotape at 1/7th and 1/15th. Bacterial speeds were: Campylobacter 29.2 micron/s, E. coli 8.9 micron/s and P. aeruginosa 16.8 micron/s.
