Scientists have learned to cheat the bacteria

Bacteria have no nervous system, and the movement almost chaotic.

It is known that bacteria are able to move them to useful objects such as food by using the chemotaxis (reaction to a chemical stimulus). This year, four Swiss microbiologists found that in addition to chemotaxis in bacteria is a kind of touch – the ability to feel touch. The researchers were able not only to unravel the bacterial mechanism of touch, but to deceive him.

The feeling of surface is very important for bacteria: partly thanks to him they learn a suitable place to live (for example, the intestinal wall or mucosa). The ability to feel touch directs the movement of bacteria and helps to colonize large areas of suitable surfaces. The infection success is also often dependent on bacterial “sense of community”: the bacteria form a film community of millions of cells that are more resistant to antibiotics than individual groups of bacteria.

The researchers, led by distinguished Professor of biology Yves Bruno learned how the bacteria find and cling to the surface. Many bacteria have flagella – organelles that unicellular use as a paddle. The movement of the flagellum causes the diaphragm motor. Swiss biologists have found that due to motor are harmless to humans bacteria Caulobacter crescentus is able to feel a touch to the surface and react to it. The flagellum of C. crescentus acts as a probe; bumping into an obstacle, its receptors trigger a cascade of reactions that completes synthesis of the active sticky polysaccharides, with which the bacterium is attached to the surface. To trick the bacteria in the sense of surface, team Bruno has made a big molecule of maleimide to drinking, to effectively block the movement of these structures.
