Determination of bacterial swimming speed in methylcellulose and Ficoll viscosity solutions. (a) Negative stained images of the bacterial strains tested; A. butzleri, C. jejuni wild type, C. jejuni Δpgp1 mutant (straight cell type), S. enterica, and W. succinogenes. (b) Cell size measurements of individual cells from each type. Swimming velocities of strains in methylcellulose (c) or Ficoll (d) solutions of increasing viscosity, reported as the average swimming speeds of two independent cultures, recorded in triplicate, containing the swimming speeds of >600 individual cells and reported in µm/sec ± one standard deviation.
