Does streptococcus pneumoniae have fimbriae?
Frimbriae are structures related to Gram-negative bacteria. S. Pneumoniae, however, is Gram-positive. Therefore it does not have fimbriae.
Why is blood agar considered s differential medium?
its made from blood Blood agar is enriched because of the nutrients in it, including blood from various mammals, mainly sheep. Many types of bacteria can grow on blood agar. It is differential because organisms can be "differentiated" based on the type of hemolysis present on the agar as they grow. The blood cells in the agar are either completely lysed as the bacteria grows, which results in beta hemolysis, or a clear halo around the bacterial colony. If the blood cells are partially lysed, alpha hemolysis results and appears as a green halo around the colony. If no blood cells are lysed, this is called gamma hemolysis which is really no hemolysis at all. The colony will appear as just the colony with the blood agar unchanged. This is helpful in determining a preliminary identification of certain organisms such as Staphylococcus aureus, which is beta hemolytic and Streptococcus pneumoniae, which is alpha hemolytic. Differential agars help to differentiate bacterial species based on their metabolic processes as they grow. Hope this answer helped to clarify a bit more than the previous one!
