andreev551 [17]

Answer:

All of the options are true for a MRSA infection.

Explanation:

<em>Staphylococcus aureus</em> is one of the most frequent pathogens causing hospital and community infections. <em>S. aureus</em> can become very easy methicillin resistant (called MRSA isolates) and others beta-lactam antibiotics (are the ones widely used to treat infections) and usually can be resistant to other class of antibiotics, become a  very strong bacteria making treatment options very limited. MRSA isolates can rapidly transfer the methicillin resistance to other species of S<em>taphylococcus</em> and some other bacteria. Also <em>S. aureus</em> can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat  MRSA infections  with the hope that can´t develop resistance to this new drugs.
