Summary[edit]

Description
English: Hanging drop observations of M. bavaricum and cocci. Hanging drop assay showing M. bavaricum and unspecified magnetotactic cocci accumulating along the right edge of a water drop. The local magnetic field generated by Helmholtz coils is parallel to the observation plane and points to the right, as indicated by the white line inscribed in a circle. Therefore, MTB cells accumulating on the right edge are north-seeking (NS). M. bavaricum is easily distinguishable from cocci because of its elongated shape and larger size. During the first two parts of the video, few M. bavaricum cells, already immobilized in the partially dried drop edge, are surrounded by highly motile cocci performing backward loops not observed in case of freely swimming cells. The third part of the video shows another region of the drop edge with more, still motile M. bavaricum cells. The last part of the video show M. bavaricum and cocci swimming away from and back to the drop edge after reversing the field direction twice.
