Scientists from the University of California (USA) have found out how the bacteria manage to move and spread with such rapidity. It was found that for the movement bacteria   use special hooks - hair or processes pili   and as climbers overcome obstacles.

In addition, in the arsenal of the bacteria there are specific maneuvers, allowing to receive acceleration   when traveling. By acting on these processes, as scientists say, can seriously hamper the spread of infections in hospitals.

The object for study and experimentation became a bacterium Pseudomonas aeruginosa   or Pseudomonas aeruginosa Characterized by the rapid proliferation and resistance to many antibiotics. The researchers were able to film the entire process of movement bacteria in a viscous medium on the glass. It revealed algorithm movements.

As it turned out, bacteria, moving, throws forward fimbriae and reducing them tightened. Also by zakidyvaniya one elastic process, the bacterium is able to achieve a significant acceleration and overcome space up to 20 times faster. Thus, due to the high speed when the snatch viscosity of the medium decreases, which also increases the speed of movement of the bacteria.

By blocking these abilities, scientists plan razrabatat modalities that prevent the spread of infections.
