Nara Medical University study confirms that ozone inactivates SARS-CoV-2

Nara Medical University (Professor Toshikazu Yano, Director of Infectious Diseases, Takashi Kasahara, Director of Infectious Diseases) and MBT Consortium (members of the Subcommittee on Infectious Diseases: Quorl Holdings Co., Ltd., Sanyu Shoji Co., Ltd., Tamuratec Co., Ltd., Marusan Pharmaceutical Biotech Co., Ltd.)

The company’s research team was the first in the world to confirm the inactivation of the new coronavirus by exposure to ozone gas.

“We also demonstrated academic practicality by experimentally clarifying the inactivation conditions”

The need to sterilize environments and equipment as a consequence of COVID-19 involves a lot of effort and time for manual cleaning.

One of the tools available to solve this problem was sterilization with ozone gas, but without clear scientific evidence, it was not possible to certify its use.

A research team led by Nara Medical University has been able to inactivate new coronaviruses through exposure to ozone gas.

In this report, we report that ozone inactivation of the new coronavirus has been conducted and the relationship between ozone concentration and exposure time and ozone inactivation has been clarified experimentally.

Ozone (chemical formula: O3) is an allotropic form of oxygen, with a characteristic garlic-like odor. Its molecules are made up of three oxygen atoms.

It has the strongest oxidative power close to fluoride and destroys cells like bacteria and decomposes the chemical bonds between substances.

It is effective in deodorization, sterilization and cleaning and is used in various fields such as medical care, nursing care, breeding and in the food sector.

As for the effectiveness of ozone, the bactericidal power of 7 times that of chlorine and has been considered “particularly effective” for the control of infectious diseases.

In Japan, the fire department of the Ministry of Internal Affairs and Communications introduced it to Japan for the first time in 2008, when it identified it as part of the measures to prevent the new flu infection and authorized its use in main airports.

Since then, application on medical sites has progressed and the number of medical institutions introducing ozone generators for the purpose of preventing the spread of healthcare associated infections has been increasing.

The bactericidal ozone-based approach has also been accepted as a measure against new coronavirus infection (COVID-19).

Since January of this year, when COVID-19 infection was spreading around the world, not only medical institutions, but also ambulances, hospitals, hotels, etc. have adopted ozone generators.

Ozone has definitely gained widespread use as an effective sterilization method comparable to manual alcohol cleaning.

Experiment content and procedure

  • Cultivate a new cell line of coronavirus,
  • place a stainless steel plate in an ozone-proof hermetic box installed in a safety cabinet,
  • apply the new coronavirus to be tested.
  • Use an ozonator (medical device certified by PMDA: ozone generator) installed in the ozone-proof hermetic box, the ozone concentration in the ozone-proof hermetic box is controlled and maintained from 1.0 to 6.0 ppm.
    The amount of ozone exposure is set by the CT value. (The CT 330 value is used, which is a verification test value for the certification of medical devices by the PMDA of the Ministry of Health, Labor and Wellness).
  • After exposure, inoculate the cells with the virus,
  • determine if the virus has infected the cells and calculate the amount of virus.

This experiment was possible because the University has a biosecurity level 3 laboratory and virus culture technology.

  1. With a CT value of 330 (55 minute exposure to an ozone concentration of 6 ppm), it was inactivated from 1 / 1,000 to 1 / 10,000.
  2. At a CT value of 60 (60 minutes of exposure to an ozone concentration of 1 ppm), it was inactivated from 1/10 to 1/100.

Experimental device

In this study, we confirmed that ozone can inactivate up to 1 / 10,000.

This shows that in real conditions and using ozone, the new coronavirus can be inactivated on all surfaces and used in the sanitization of environments.

But ozone therapy as a medical therapy, validated by the numerous world scientific researches, has an anti – bacterial / viral / fungal power and in particular anti inflammatory.


MECHANISM OF ACTION

Inactivation of bacteria, viruses, fungi, yeast and protozoa:

  • Ozone therapy disrupts the integrity of the bacterial cell envelope through oxidation of the phospholipids and lipoproteins.
  • In fungi, O3 inhibits cell growth at certain stages.
  • With viruses, the O3 damages the viral capsid and upsets the reproductive cycle by disrupting the virus-to-cell contact with peroxidation.
  • The weak enzyme coatings on cells which make them vulnerable to invasion by viruses make them susceptible to oxidation and elimination from the body, which then replaces them with healthy cells.[26]

Stimulation of oxygen metabolism: Ozone therapy causes an increase in the red blood cell glycolysis rate.
This leads to the stimulation of 2,3-diphosphoglycerate which leads to an increase in the amount of oxygen released to the tissues.

Ozone activates the Krebs cycle by enhancing oxidative carboxylation of pyruvate, stimulating production of ATP.

It also causes a significant reduction in NADH and helps to oxidize cytochrome C.
There is a stimulation of production of enzymes which act as free radical scavengers and cell-wall protectors: glutathione peroxidase, catalase and superoxide dismutase.

Production of prostacyline, a vasodilator, is also induced by O3 [Figure 1].[25]

Activation of the immune system: Ozone administered at a concentration of between 30 and 55 μg/cc causes the greatest increase in the production of interferon and the greatest output of tumor necrosis factor and interleukin-2.

The production of interleukin-2 launches an entire cascade of subsequent immunological reactions.[27]

ADVANTAGES OF OZONE THERAPY

  • Diabetic complications are attributed to the oxidative stress in the body, O3 was found to activate the antioxidant system affecting the level of glycemia.
  • Ozone prevented oxidative stress by normalizing the organic peroxide levels by activating superoxide dismutase.[36–37]
  • Ozone was found to completely inactivate the HIV in vitro, this action of O3 was dose-dependent.
  • Concentration used for inactivation was found to be non-cytotoxic. The inactivation was owing to the reduction of the HIV p24 core protein.[38]
  • Ozone was also found to increase the host immunity by increasing the production of cytokine.[39]
  • In an in vitro study, it was observed that O3 is very effective in reducing the concentrations of Acinetobacter baumannii, Clostridium difficile and methicillin-resistant Staphylococcus aureus in dry as well as wet samples, hence it can be used as a disinfectant.

Ozone: A Potential Oxidant for COVID-19 Virus (SARS-CoV-2)

New white paper available from the IOA on the use of ozone to inactive the COVID-19 (SARS-CoV-2) virus. Abstract and summary below, full paper can be found HERE:

https://www.tandfonline.com/doi/full/10.1080/01919512.2020.1795614

ABSTRACT

Currently, no medicine has demonstrated efficacy in treating the ongoing pandemic COVID-19 caused by SARS-CoV-2 virus. Being a potent oxidant, ozone is lethal against most bacteria and viruses found in water, or on surfaces and aerosols. Ozone has also been successfully used to treat several viral diseases such as Ebola and HIV Hepatitis B and C. Using molecular modeling, this study evaluated the reactivity of ozone toward representative key molecules in the structure of SARS-CoV-2. The results show that ozone is able to attack the proteins and lipids of the virus’s spikes and envelope, particularly the amino acids tryptophan, methionine and cysteine, and the fatty acids, arachidonic acid, linoleic acid, and oleic acid. Ozone also attacks the N-glycopeptides of the spike protein subunits 1 and 2, though at lower reactivity. Disruption of the structure of SARS-CoV-2 could inactivate the virus, suggesting that ozone could be an effective oxidant against COVID-19 virus. If incorrectly applied, ozone is toxic and contact with the respiratory tract must be avoided.

Summary:

Ozone has been used successfully to inactivate pathogens and viruses in many applications and has a long history of success. Based on this the assumption is made that ozone will also inactivate the SARS-CoV-2 virus. This study uses representative viruses, and molecular modeling to provide that ozone could be an effective oxidant against SARS-CoV-2. Ozone was able to attach the proteins and lipids of the virus destroying the integrity of the virus rendering it unable to cause further infection or reproduction.

How to Dismember Corona Virus with Ozone

Given the mountain of evidence that ozone is a quick and effective destroyer of viruses and bacteria, why is there so much hesitation to champion ozone as a key weapon against the spread of Covid 19? The EPA has a list of 478 different products and 30 active ingredients that officially kill the Covid virus, but ozone is nowhere to be found in the list. The closest thing to ozone that is on the list is hydrogen peroxide. Have all these products actually been applied to the virus and proven to destroy or inactivate it? How can you tell if a virus is dead or inactive? Given what we are gradually learning about the virus, how it spreads, and how it infects our bodies, how effective are these disinfectants in preventing infection?

Dr. Chedly Tizaoui, a professor of chemical engineering at Swansee University has taken a rather novel approach in an attempt to answer some of these questions. Instead of conducting statistical analysis of thousands of people or trying to count dead viruses after applying a particular disinfectant, Dr. Tizaoui has applied molecular modeling to evaluate the effect of ozone on the molecular structures the virus. He shares his results in the International Ozone Association research journal “Ozone: Science and Engineering” https://www.tandfonline.com/doi/pdf/10.1080/01919512.2020.1795614?needAccess=true

Molecular modeling is an especially useful tool for studying viruses because viruses are so small they can’t be seen with a standard light microscope. Their shape and structures are defined on a molecular level, so understanding the types of molecules making up their structure allows us to make an accurate model. The model not only evaluates the shape and function of corona virus anatomy, but it also evaluates the bonds holding these molecules together. Understanding the relationships between these molecules and how they function together to make the Corona Virus so sucessful provides important insight in the weaknesses and vulnerabilities of the virus.

We may not yet know all the complex interactions of the virus with people, or exactly how the virus infects, but we do have a pretty clear understanding of the molecular structure of the virus. It is also clear that the unique shape and structure of the molecular structures on the outer shell play a key role in the success of the virus. Molecular modeling is a tool that helps us see how this structure is altered when a molecule like ozone comes into contact with it.

Ozone is like a molecular hand grenade in the virus world and has the power to change the shape of the virus’s “arms” and disable them. Various kinds of molecules behave and react in predictable ways making it possible to use molecular modeling to study what happens when something like ozone molecules interacts with the structures on a virus.

Ozone is an exciting molecule to model because it packs a lot of energy. The molecule is very sensitive and quick to unload its energy on nearby molecules. It has a very positive 100 year track record for effectively destroying viruses and bacteria. The water treatment industry has grown to appreciate the value of ozone for destroying pathogens in water. The food industry is also learning how to harness its power for sanitation and shelf life extension. Ozone has also been used extensively in medical treatment, but faces an uphill battle against the pharmaceutical and chemical industries.

After applying the science of molecular modeling to Corona Virus anatomy and ozone, Dr. Tizaoui concludes, “The results show that ozone is able to attack the proteins and lipids of the virus’s spikes and envelope, particularly the amino acids tryptophan, methionine and cysteine, and the fatty acids,varachidonic acid, linoleic acid, and oleic acid. Ozone also attacks the N-glycopeptides of the spike protein subunits 1 and 2, though at lower reactivity. Disruption of the structure of SARS-CoV-2 could inactivate the virus, suggesting that ozone could be an effective oxidant against COVID-19 virus.”

Thank you, Dr. Tizaoui, for sharing this research. Now it’s our job to safely get the ozone where it needs to be to do its work.

Good and Evil of Ozone

The ozone hole is slowly healing

The Coronavirus pandemic has sparked an exponential increase in interest in ozone as a disinfectant. The phones at Oxidation Technologies have been ringing non-stop with people looking for answers and looking for help with their grand ideas for ozone as a silver coronavirus bullet. Our ozone specialists have been working hard to provide accurate information for those looking for answers. Ozone has been a powerful tool for over a hundred years, but misinformation is dangerous in a climate of desperation and hype. Our goal throughout this health crisis has been to educate our callers about safe and unsafe uses of ozone, effective and ineffective applications of ozone, and the facts and false claims people make about ozone.

If there is so much interest in ozone as a powerful and chemical-free disinfectant, why do we read so much about ozone as a very bad and deadly pollutant? For example, the American Lung Association says “Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U.S.”  On the other hand, the Food and Drug Administration (FDA) approved the use of ozone as an antimicrobial agent for the treatment, storage and processing of foods in gas and aqueous phases.” For years, now, we have recognized the value of an atmospheric layer of ozone that shields “living things from too much ultraviolet radiation from the sun.” Ozone sterilization of water has made the bottled water industry possible providing billions of bottles of safe drinking water. The answer to this paradox is not difficult or mysterious, but does require some ozone education. We hope you take some time to explore the wealth of ozone information on our website.
