MRSA-Killing Paint Created

Scientists at Rensselaer Polytechnic Institute has developed a high tech paint that safely kills MRSA. This special paint was developed for use on surgical equipment, hospital walls, and other surfaces. When MRSA touches this special coating, it dies preventing the main way this germ travels from one person to another (which is by contact). 100 percent of MRSA in contact with this special paint were killed within 20 minutes.

The paint contains a naturally occurring enzyme called lysostaphin contained within carbon nanotubes. This compound can be mixed into ordinary house paint before application.

Unlike other antimicrobial coatings, it is toxic only to MRSA, does not rely on antibiotics, and does not leach chemicals into the environment or become clogged over time. It can be washed repeatedly without losing effectiveness and has a dry storage shelf life of up to six months.

New Convenient MRSA Antiseptic Gel Product

It was brought to my attention recently about a product used to help treat and prevent active MRSA skin infections called StaphASeptic. The product contains two ingredients: benzethonium chloride (kills MRSA) as well as lidocaine (numbs the skin). The lidocaine is helpful in that some MRSA skin infections are quite painful. This product can be found and purchased at Amazon.com in varying quantities from 2 oz tube, 4 oz tube, or packets.
