Flagellum in bacteria
WebBacteria swam more smoothly due to a counterclockwise rotation of their flagella in the presence of increasing attractant. In a decreasing attractant gradient, there is an increase in bacterial tumbling, produced by a clockwise flagellar rotation. WebAug 3, 2024 · Flagellated bacteria preloaded with cancer drugs offer promise in medicine. Magnetosomes carry the iron crystals, and these crystals can naturally navigate to the right body organs. But it takes the flagellum to propel the bacteria loaded with drugs and magnets to cancerous organs. Motility via flagella is key in bacterial therapy, since ...
