Understanding MRSA - There has been plenty in the news lately about MRSA. MRSA is Methicillin-resistant Staphylococcus aureus.
Is Your Antibacterial Soap Keeping You Sick?
Many people use antibacterial soaps every day, thinking that they will help to kill germs like those that cause MRSA and keep them healthier. However, a University of Michigan public health professor thinks that they might not work any better over regular soaps. On top of this, the may actually make some antibiotics less effective.

Allison Aiello did a study on whether or not antibacterial soaps work better than regular ones. The surprising results that her team came up with were that plain soap prevents infectious illness just as well as antibacterial soap. Besides this, the antibacterial soaps that you can buy in the store do not remove any more bacteria than regular soap.

Most antibacterial soaps contain the ingredient triclosan. Because of the way that triclosan reacts in the cells it may even cause bacteria to become resistant to amoxicillin a commonly used antibiotic. While this has not been seen on a large scale yet, e-coli bacteria used in lab experiments started showing resistance to the antibiotics after being exposed to .1% weight per volume triclosan soap. This could lead to more antibiotic-resistant super bugs like MRSA.

What this means is that at the concentrations triclosan is found in your average antibacterial soap, the e-coli bacteria could still survive on your hands. What that means for you the consumer is that there is no real reason to spend extra money on antibacterial soaps, when the regular kind work just as well at reducing bacteria.

The study was published in the August 2007 edition of “Clinical Infectious Diseases.” Over the course of the study, the team investigated 27 studies done between 1980 and 2006. The studies found that soaps containing triclosan, in the range that you can typically buy at the store, were not any more effective than regular soap. In hospital settings, triclosan is effective at reducing illness and bacteria; however, the concentration in professional formulation is much higher than what the average consumer can buy.
Your Pet Could Be a Carrier of MRSA - Staph infections have always been a concern in hospitals, particularly MRSA which is resistant to many antibiotic treatments. MRSA has also been showing...
The way that triclosan works is by interfering with the pathway in the bacteria that keeps the cell wall intact. Without this ability, the bacterium dies. However, because of the way it works, mutation can occur. If this happens, there is the potential that triclosan will no longer be effective at killing the bacteria. In the case of a super bug like MRSA, this is one more weapon from the arsenal lost, leaving doctors with even fewer ways to kill the bacteria.
A Definition of MRSA - First off, you will probably want to know what MRSA stands for. It is Methicillin Resistant Staphylococcus Aureus or Multiple Resistance Staphylococcus...
Keep in mind that there are different antiseptic products on the market, and not all of them use triclosan – others may use alcohol or bleach. These were not investigated during the study.
So, when washing your hands to prevent diseases like MRSA, it is not so much the soap that matters. The scrubbing action itself, combined with the cleaning action of the soap, will help wash most of the bacteria down the drain. Complimenting your hand washing routine with alcohol-based hand sanitizers can help finish off any germs that might remain and add to your protection.© Information Warehouse 2007
