Structure and PhysiologyStaphylococcus aureus is a Gram-positive, coccal-shaped, facultative anaerobic bacterium. During binary fission, the two daughter cells that are produced do not completely separate. Incomplete separations of the cells result in the cluster formation. S. aureus is a catalase-positive bacterium that is able to combat the electronegative oxidizing...

Staphylococcus aureus (MRSA)

Structure and PhysiologyMethicillin-resistant Staphylococcus aureus (MRSA) is a Gram-positive, coccal-shaped, facultative anaerobic bacterium that is responsible for many difficult to treat infections. MRSA is any strain of Staphylococcus aureus that has developed a resistance to beta-lactam antibiotics through the process of natural selection. Beta-lactam antibiotics include penicillin, methicillin, dicloxacillin,...
