| Description: |
Bacteria propel and change direction by rotating long, helical filaments, called flagella. The number of flagella, their arrangement on the cell body and their sense of rotation hypothetically determine the locomotion characteristics of a species. The movement of the most rapid microorganisms has in particular remained unexplored because of additional experimental limitations. We show that magnetotactic cocci with two flagella bundles on one pole swim faster than 500 μm·s-1 along a double helical path, making them one of the fastest natural microswimmers. We additionally reveal that the cells reorient in less than 5 ms, an order of magnitude faster than reported so far for any other bacteria. Using hydrodynamic modeling, we demonstrate that a mode where a pushing and a pulling bundle cooperate is the only possibility to enable both helical tracks and fast reorientations. The advantage of sheathed flagella bundles is the high rigidity, making high swimming speeds possible. ; MC1_3Dtracks Experimental data from the lab; created with MatLab, saved as .mat files. The .mat files include structs. Most important is the Bugs cell that includes 5 columns, first column is the line number, second to fourth is x,y,z coordinates and fifth is the correlation value as a representation of the certainty of the finding. Created with an adapted version from the Nature Communication article by Taute et al. from 2015. Comes with 2 example reading and analysing scripts for MatLab.
