streptococci like S.mutans grow on this medium.. may be other anaerobic pathogenic streptococci(animals) also grow in this medium . Listeria monocytogenes, a gram positive foodborne pathogen, also grows very well on this medium and may actually show better hemolysis zones than when grown on regular sheep blood agar.

Can Lactobacillus grow on blood agar?
yes
Will p. aeruginosa grow on a blood agar media?
no
A bacterial species that grows on blood agar but will not grow on trypticase soy agar is termed an anaerobe?
false
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!
What is the composition of modified nutrient glucose agar media?
Modified nutrient glucose agar is composed of agar, water, glucose, extracts, peptone and sodium chloride. Modified nutrient glucose agar allows organisms to grow.
What type of medium is blood agar?
Blood agar is media rich in reb blood cells and the most commonly used type of media is horse blood media. It is useful for the isolation of bacteria such as Streptococci or organisms that would not readily grow on media that lack red blood cells. For the isolation of Streptococci it is also useful in observing alpha and beta haemolysis.
Can Lactobacillus grow on blood agar?
yes
Will p. aeruginosa grow on a blood agar media?
no
Does pseudomonas aeruginosa grow on blood agar?
Yes.
What type of semisolid medium is used to grow bacteria?
Agar is a semi solid medium used to grow bacteria.
What kind of agar should be used to grow bacteria from hands before and after washing for a grade 8 science fair?
blood or nutrient agar would work, but blood agar will most likely grow more bacteria.
Why 7.5 percent sodium chloride agar is selective media?
Because 7.5% NaCl agar inhibits gram negative organisms from growing, and is "selective" in that only gram positive organisms can grow in this type of agar.
A bacterial species that grows on blood agar but will not grow on trypticase soy agar is termed an anaerobe?
false
Can Klebsiella pneumoniae grow on Mannitol salt agar?
No, K. pneumoniae will not grow on Mannitol Salt Agar- gram negative organisms cannot grow on MSA, and K. pneumoniae is gram negative.
What gram positive cocci fails to grow on blood agar but grows well on chocolate agar?
Haemophilus influenzae
What fastidious organisms grow only on chocolate agar?
Most pathogenic organisms will grown on chocolate agar, it depends mostly on the incubation conditions i.e. temperature, presence/absence of oxygen etc. However there are some fastidious organisms that require certain growth factors to grow.
What is the composition of modified nutrient glucose agar media?
Modified nutrient glucose agar is composed of agar, water, glucose, extracts, peptone and sodium chloride. Modified nutrient glucose agar allows organisms to grow.
