Cigarette smoke makes the deadly MRSA superbug even stronger, according to a new report from the University of California, San Diego School of Medicine.

Researchers concluded that cigarette smoke strengthens the MRSA bacteria's cell wall. Thus, the MRSA cell can repel peptides and other immune system mechanisms intended to defeat the dangerous bacteria. MRSA bacteria also invaded human cells more aggressively when treated with cigarette smoke.

"Cigarette smokers are known to be more susceptible to infectious diseases. Now we have evidence that cigarette smoke-induced resistance in MRSA may be an additional contributing factor," said study author Dr. Laura E. Crotty Alexander.

An antibiotic-resistant superbug, MRSA is known to cause skin and blood infections and pneumonia. Last month, researchers at the University of Nottingham discovered a promising antibiotic-free MRSA treatment comprised of garlic, onion, cow bile and wine.
