Two Different Types of Staff Infections, MRSA is the More Aggressive

Kennewick, Wash, - There are two types of staph infections.

Methicillin Sensitive Staphylococcus Aureus, or MSSA, which is easier to treat

the other type of staph, MRSA, which can be fatal.

Surprisingly, cases of the deadly strain of bacteria have been present in our community for some time.

MRSA can cause serious soft tissue damage. Over the years, infectious disease specialist Dr. Olympia Tachopoulou says the bacteria acquired a toxin called PVI, making it more aggressive and resistant to treatment.

"Staphylococcus aureus, which is a scientific name, acquired new genes that make it produce toxins that can cause these more aggressive infections" said Dr. Tachopoulou.

"In the tri-cities, we have noticed that about 50 to 60 percent of the staphylococcus aureus isolates are MRSA" Tachopoulou continued.

In early 2005, 40 percent of staph infections were MRSA, by October 2007 the percentage of MRSA cases has climbed to 50 percent.

MRSA can be treated, locally an 11 year old Hermiston boy diagnosed with a skin version of MRSA has returned to school.

It's when MRSA gets into the bloodstream; it can attack the heart, brain and other organs, and be deadly.
