WAKEFIELD, Massachusetts - 13. june 2005 - AgION Technologies, Inc.a leading provider of engineered antimicrobial solutions, today announced that its research efforts have demonstrated that ionic silver was found to effectively inactivate a strain of human coronavirus 229E, a virus associated with SARS, during a laboratory study conducted by the University of Arizona.
The study led by C.P. Gerba, Ph.D. a K.R. Bright, Ph.D., tested different levels of ionic silver and copper to determine whether they were effective against the 229E strain of human coronavirus, a strain commonly used as a surrogate for the SARS virus in laboratory research. The study showed a significant reduction of virus within 1 hour (90 percent) and reduced virus levels below the detection limit after 24 hours of exposure (99.99 percent).
"Research shows that ionic silver has the potential to deactivate viruses in a relatively short time."
"These are very exciting results," said Dr. Good. "The fact that ionic silver is effective against this strain of human coronavirus suggests that it may also be effective in reducing the human SARS virus, which causes widespread disease in many countries around the world. Because the compound is both safe and effective, there are countless potential applications. "
This study supports previous findings from research on human SARS virus and feline coronavirus. A 2003 study by the Chinese Center for Disease Control and Prevention found that ionic silver completely deactivated the human SARS virus after 2 hours. In addition, a laboratory study conducted by the University of Arizona in 2003 found that ionic silver deactivated 99% of feline coronavirus within 4 hours.
"Research shows that ionic silver has the potential to deactivate viruses in a relatively short period of time," said Jeff Trogolo, Ph.D., Chief Technology Officer, AgION Technologies, Inc. "Studies have shown that coronaviruses can survive on surfaces for hours - even days in some cases - so there is exciting potential for AgION technology to evolve into solutions that are used to reduce these viruses on contaminated surfaces.
The antimicrobial compound Agion consists of naturally occurring silver ions and a ceramic material called zeolite. It is safe, long-lasting and proven effective against a wide range of microorganisms, including bacteria, algae and fungi such as moulds and yeasts. Agion antimicrobials are used in a wide range of applications and can be found in appliances, building products, heating, ventilation, air conditioning, medical equipment, water filtration and delivery, food processing and packaging, and a variety of other consumer, industrial and medical products. AgION antimicrobials are not currently registered with the Environmental Protection Agency to demonstrate efficacy against coronaviruses.
