Although bacteria do not have the central nervous system, they can "feel" the world around.
In a study conducted by researchers from the University of Basel, it was discovered that these small microorganisms do not only have the ability to respond to chemical signals but already have a sense of touch. This means that they can recognize different surfaces and act accordingly.
For people, touch sensation is very important because it helps us to recognize and avoid dangerous areas. Bacteria allow this sensor to recognize the type of surface they are in contact with. Scientists believe that what is happening within the first few seconds after contact with the surface is essential for successful infection.
In order to find the mechanism by which the bacterium serves to sensitize the surface, scientists have studied the harmless type of Caulobacter crescentus bacteria
Scientist Urs Jenal said, "We do not know much about how bacteria recognize mechanical stimuli and how they change their behavior. With the help of unpopular Caulobacter bacteria, we have been able to prove for the first time that bacteria have a "touch sensation". This mechanism helps them recognize surfaces and begin producing their own adhesin inside cells. "
Some bacteria have a flagel called flagelum and allows them to move. Some have only one and some more flagelum. The young C.crescentus bacteria have only one whip, and their number increases after a while. Because of the flagelum rotation, the bacteria can move through the fluid. But these microorganisms do not have muscles, but move with the energy they give them the proton flow through the cell membrane.
This mechanism allows bacteria to "feel". When the cells come into contact with the surface, the engine operation triggers the flagelum. This is why the proton flow is disturbed. Within a few seconds, the response of the bacterium that begins to produce an adhesive that will fix them on this surface is generated.
Although the bacteria they have studied harmless, scientists believe that they will discover this through understanding and further exploration of infectious diseases.
