Staphylococcus aureus is known to produce coagulase, which can clot plama into gel in tube or agglutinate cocci in slide. This test is useful in differentiating S.aureus from other ...
It makes sense that two organisms in the same niche should compete for space and resources. Far more interesting is the fact that sometimes fungi and bacteria will work together in ...
Haemophilus spp does not grow on 5% Sheep Blood Agar, which contains hemin (factor X) but lacks NAD (factor V).
Haemophilus influenzae will grow in the hemolytic zone of ...
Coagulase is an enzyme that catalyzes the formation of a fibrin clot in plasma. Obvious clumping of the bacteria indicates the bacteria produces bound caogulase.
Staphylococcus aureus ...
– gram positive cocci
– nonmotile
– Catalase: positive
– Oxidase: negative
– facultative anaerobic

Mannitol salt agar (MSA) is a differential and selective media. It is selective because its high salt concentration (7.5 %) inhibits the growth of most bacteria. However, Staphylococcus ...
Colonies of Staphylococcus aureus on blood agar surrounded by wide zones of beta-hemolysis.
s.aureus is positve for fermenting mannitol
note the complete changing in color of the agar
compare with the other post of s. epidermidis.
