Makes copious amounts of biofilms (a mess of polysaccharides, helps it stick to surfaces and acts as coating that protects it from antibiotics and immune cells) therefore resistant to many antibiotics.

Causes pneumonia вЂ“ patchy infiltrates on xray, icosahedron shaped lamps (capsules) post-viral bacterial pneumonia. Protein A вЂ“ main virulence factor, component of cell wall and binds Fc portion of Ig and prevents opsonization. Plate on mannitol salt agar вЂ“ can ferment and turn agar yellow. Coagulase positive (converts fibrinogen to fibrin). Gram positive (take up crystal violet stain in their thick cell walls). Suggested printing template (6 slides per page): 1Д«undle of grapes.
