"Silver" is also effective for bacteria, it is possible to elicit the effect of antibiotics 10 to 1000 times


The team led by Mr. James Collins who is a biomedical engineer at Boston University in Massachusetts unveiled how silver will divide bacteria. It showed that it might become possible to take more effective means against antibiotic-resistant bacteria.

Silver Enhances Antibiotic Activity Against Gram-Negative Bacteria

Silver it antibiotics thousands of times more effective: Nature News & amp; Comment

Precious metals have been used to fight infectious diseases for thousands of years since Hippocrates described about the fact that precious metals originally had antimicrobial properties in 400 BC, but how it works Whether it was a mystery left.

Collins and his team clarify that ionically degraded silver is attacking bacterial cells in two main ways. One is to increase the permeability of the cell membrane and the other is to increase oxygen compound production and interfere with cellular metabolism. This will allow antibiotics to act more effectively.

Gram negative bacteriaBacteria such as Stenotrophomonas maltophilia often have smaller bacterial cells than the molecules that make up the antibiotic so antibiotics can not penetrate into it. However, the increased membrane permeability due to the silver effect allows more antibiotics to enter the bacterial cells and increases the rate of penetration of these resistant bacteria. When antibiotics are strengthened with a small amount of silver, it seems that the antibiotic has inhibitory effect on bacterial growth and function from 10 times to 1000 times as normal.

Vance Fowler, an infectious disease physician at Duke University in North Carolina, says, "The effect of silver is wonderful, but we need to pay close attention to the toxicity of silver." Ingestion of a large amount of silver may cause silver poisoning (a state in which the skin turns a blue gray color), but if ingested by coating a small amount of antibiotic with a small amount of silver, a large effect on bacteria It is also known that we will be able to obtain antibiotics that are stronger than ever in the near future due to the work of silver.
