the Dead bacteria continue to destroy the sight.

a Team of Israeli scientists found that the nitrate of silver causes a kind of "zombie Apocalypse" in the cells of Escherichia coli. Dead bacteria continue to destroy the sight. The result of the study published in the Scientific Reports website.

the study of antibacterial effect of silver, researchers found that Pseudomonas aeruginosa, or Escherichia coli, dying from nitrate of the precious metal continued to kill live bacteria. Scientists have dubbed this process "the zombie effect".

the Researchers linked the deadly properties of dead bacteria with the chemical principle of Le Chatelier (occurrence in equilibrium system of forces trying to shift this balance, causing the resistance to this process). the

In the environment of dead Pseudomonas aeruginosa establishes the equilibrium between the silver concentration inside the bacteria and in the environment. After hitting dead bacteria from the system in a pure culture of Pseudomonas aeruginosa and the current balance is disturbed, the cell-zombies will wear silver bacteria into the surrounding space. This leads to the alignment of equilibrium and death healthy sticks. In this case, the researchers note, the dead bacteria cope with the destruction of live cells as effective as the nitrate of silver.



Antibacterial properties of silver have been known since ancient times. Hippocrates noted that this precious metal was helping in the fight against certain diseases. And according to Persian Chronicles, the rulers used to store water in silver vessels. the "the Persian king, going to war, he always took the food, thoroughly - cooked at home, and livestock. He also took water from the river that flows through Susa, for drinking as soon as she was to the king's taste. Whenever he travelled, he was accompanied by several wagons drawn by mules, which transported the water already boiled for drinking and poured in a silver jar", wrote Herodotus.

However, due to the fact that silver is a heavy metal that, when ingested in large quantities, impairs the functioning of cells. For example, can cause discoloration of the skin on a silvery or bluish-gray.
