Bacteria have a sense of touch

http://ift.tt/eA8V8J Although bacteria have no sensory organs in the classical sense, they are still masters in perceiving their environment. A research group has now discovered that bacteria not only respond to chemical signals, but also possess a sense of touch. The researchers demonstrate how bacteria recognize surfaces and respond to this mechanical stimulus within seconds. This mechanism is also used by pathogens to colonize and attack their host cells.
