New MRSA Bacteria Killer Registered by EPA

04 Sep 2005

http://www.medicalnewstoday.com/medicalnews.php?newsid=30105

The EPA (Environmental Protection Agency) has recently registered a

new product for preventing and eliminating methicillin-resistant

Staphylococcus aureus (MRSA), which causes potentially deadly

infections commonly known as " staph " infections. The MRSA " super

bug " is typically contracted in hospitals, in other healthcare

environments, and in health clubs and locker rooms.

The EPA has registered Selectrocide™ chlorine dioxide for use as a

disinfectant on hard, non-porous surfaces and instruments, including

those used within hospitals and other medical settings. As a no-

wipe, no-rinse spray, Selectrocide chlorine dioxide can also be used

on hard, non-porous surfaces in health clubs, spas, public places

and swimming facilities as a treatment against MRSA. The EPA has

also registered Selectrocide™ as a disinfectant for vancomycin-

resistant Enterococcus faecalis, athlete's foot, Mycobacterium bovis

(TB) and other pathogens that spread in many environments.

MRSA is usually spread by direct physical contact with those already

infected or through indirect contact by touching objects (towels,

clothes, sports equipment, etc.) that infected skin has

contaminated. Consequently, any heavily trafficked area can be a

source of infection.

According to a report by the BBC News, " Staphylococcus aureus is the

leading cause of human infections in the skin and soft tissues,

bones and joints, abscesses and normal heart valves. It flourishes

in the hospital setting, producing bloodstream and surgical wound

infections, including MRSA. "

HOW SELECTROCIDE™ KILLS MRSA AND OTHER DEADLY PATHOGENS

Selectrocide™ is greater than 99% pure chlorine dioxide, an ideal

biocide because of its ability to kill viruses, bacteria, fungi, and

algae at low saturation levels (parts per million) in a manner that

does not allow pathogens to build resistance to the compound.

Prior to Selectrocide™, healthcare and health club environments were

limited to using substances like bleach and quaternary ammonium

compounds that can leave residue and require higher concentrations

than does chlorine dioxide to achieve the same antimicrobial

efficacy.

Selectrocide's chlorine dioxide is produced in water and sprayed,

mopped, or sponged onto surfaces that require disinfection. After

application, the solution is left on target surfaces and does not

require rinsing. Due to the comparatively low application

concentrations required to kill pathogens, Selectrocide is

compatible with most materials.

THE DEVELOPMENT OF MRSA AND ITS INCREASING RESISTANCE TO ANTIBIOTICS

Staphylococcus aureus (SA)-Antibiotic Resistance (General):

Throughout history, Staphylococcus aureus (SA) has been a dangerous

pathogen once it has successfully breached the normal defense

system. The first effective antibiotic against SA, penicillin,

became available in the 1940s. Soon after, SA evolved resistance to

penicillin, and by the late 1950s, 50 percent of all SA strains were

resistant. Today, fewer than 10 percent of SA infections can be

cured with penicillin.

The next weapons against SA, methicillin and cephalosporin, became

available in the 1960s and 1970s. By the late 1970s, some strains of

SA had evolved resistance to these drugs. Today, as many as 50

percent of SA strains isolated from U.S. hospitals are resistant to

methicillin. (Source: National Institutes of Health)

GENERAL BACKGROUND INFORMATION ON CHLORINE DIOXIDE AND SELECTROCIDE™

Chlorine dioxide is effective at low concentrations across a wide

range of pH (roughly 4 to 9), and, because it is a gas in its

natural state, dissipates upon exposure to sunlight As a

consequence, it is known widely as one of the most effective

inhibitors of algae, yeast, mold, fungi and viruses. However,

because transporting the gas is prohibited in all but frozen forms,

pure chlorine dioxide has heretofore been limited to use in large

concerns that employ chemical generators, such as pulp mills

(controlling slime) and municipal water systems (water purification

applications).

Similarly, in cleaning and antimicrobial knockdown applications,

pure chlorine dioxide has been unavailable, and only

with " stabilized " solutions or acidified sodium chlorite, which are

corrosive and produce significant chemical residues, could any of

the advantages of chlorine dioxide be realized.

JUST ADD WATER -- AND WAIT. Now, Selectrocide™ brings the power of

greater than 99% pure chlorine dioxide solutions to point-of-use

applications. Selectrocide™ produces chlorine dioxide simply by

submersing the product in water. The resulting chlorine dioxide

solution can be used to kill disease-bearing bacteria, yeasts,

molds, fungi and algae using spraying, washing or " dip " cleaning

methods.

Selectrocide™ makes it possible-for the first time-to generate

specific concentrations of chlorine dioxide at the point of use, at

neutral pH and with very low residuals, using only tap water.

SUMMARY OF SELECTROCIDE™ BENEFITS

* US EPA-registered as a disinfectant against MRSA, and other

potentially virulent pathogens.

* Pathogens cannot build up resistance to Selectrocide™ because it

kills harmful organisms by breaking down cell walls.

* Easy to use and does not require HAZMAT or complicated equipment

* Can be made on-site in specific quantities and in concentrations

desired. Only tap water is required to generate the chlorine

dioxide.

* Because it kills pathogens with such efficacy, Selectrocide™ may

reduce costs because fewer disinfection treatments may be required

during a given maintenance and cleaning cycle.
