The above image is a coloured transmission electron micrograph (TEM) of Methicillin-resistant Staphylococcus aureus (MRSA) bacteria during cytokinesis (cell division/cleavage).
Strains of MRSA are resistant to most antibiotic drug agents. This strain of MRSA can cause boils, abscesses and wound infections.
MRSA is known as a ‘super bug’ within hospitals, where outbreaks may be hard to control amongst immunocompromised patients. The problem is made worse because the bacteria reproduce rapidly by mitosis (cell division).
MRSA most commonly colonises in the nostrils so at many hospitals nasal swabs are taken upon admission. This is effective in minimising the spread of MRSA throughout the hospital.
