Fig. 4: Motility of various Leptospira strains on NRK or MDCK cells.

a Swimming and crawling speeds. Percentiles (boxes) and the minimum and maximum values (whiskers) of the speed data set are shown as described in the legend of Fig. 3. b The ratio of speeds measured using MDCK and NRK. The values of ratio and error were obtained from the averaged speeds and standard errors of the data set shown in a (see Supplementary Note 1 for details on error propagation). The strain names are presented by serovar names, and some of them are abbreviated: Hebd Hebdomadis, Ictero Icterohaemorrhagiae, Autum Autumnalis. Full names and the number of samples measured are shown in Supplementary Table S2.
