Staphylococcus aureus Diseases Pathogenesis Roles of bacterial virulent factors Diagnosis Methods for bacteria classification Treatment and prevention Issues
Bacteria morphology r Staphylococcus grape-like irregular clusters r Streptococcus chains or pairs r Neisseria: kidney shaped diplococci
Bacteria morphology Staphylococcus : grape-like irregular clusters Streptococcus : chains or pairs Neisseria : kidneyshaped diplococci
Bacteria culture: pigmentation r The bacteria produces liposoluble pigments which make the colonies appear in certain color. e Staphylococcus aureus golden yellow o Staphylococcus epidermidis white e Staphylococcus saprophyticus white or lemon vellow
Bacteria culture: pigmentation The bacteria produces liposoluble pigments which make the colonies appear in certain color: Staphylococcus aureus golden yellow Staphylococcus epidermidis white Staphylococcus saprophyticus white or lemon yellow
Bacteria culture: mannitol fermentation r Biochemical reactions for example, staphylococcus aureus is capable of using sugar mannitol(甘露醇) as a food source and will produce acidic byproducts of Staphylococcus aureus, Staphylococcus epidermidis, fermentation that wi‖l Streptococcus pneumoniae and Streptococcus pyogenes on mannitol salt agar plates(containing lower the ph of the 7.5% NaCl, mannitol and phenol red) media
