•Microbubble collapse in vicinity of a bacterial cell is investigated numerically.•Bubble dynamics ranges from weak jetting away from the cell to a spherical collapse.•Bubble-induced local stresses can exceed poration thresholds of cell membranes.•Bacterial cell damage can be explained solely by mec...
