Best Answer

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.

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.

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.

Trypticase soy agar are media used for bacterial growth. Actinobacteri, Firmicutes, Gammaproteobacteria and fungal bacteria can grow on these media.


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.


Why was a blood agar rather than a nutrient agar plate used for the culture from your mouth?

because blood agar contain only blood, the culture from the mouth might not grow properly, whereas nutrient agar contain mixture of nutrient and blood, therefore culture from the mouth will properly.


What organisms cannot grow 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 gram positive cocci fails to grow on blood agar but grows well on chocolate agar?

Haemophilus influenzae


Which bacteria can grow on nutrient agar?

Nutrient agar is a general purpose medium supporting growth of a wide range of non-fastidious organisms. Most any bacteria will grow on it.An example of a fastidious organism is Neisseria gonorrhea, which requires blood or hemoglobin and several amino acids and vitamins in order to grow.


How can organisms that do not use starch grow on a starch agar plate?

Organisms that do not use starch grows on a starch agar plate by using other organisms. The other organisms break down the starch into sugar and the starch intolerant organisms can complete those simple sugars.


Why is blood agar differential and enriched?

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!


Can you use blood to grow bacteria on petridishes?

Bacteria will grow in blood but no the growing medium in petri dishes should be clear agar.


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 agar is blood agar?

trypticase soy agar (TSA) mixed with sheep blood (blood agar) its one of the most used agar types for identifying bacteria, because most bacteria can grow on it, a few examples are Bacillus and Stahpylococcus (known for food poisoning) the agar also alows you to see if the bacteria does hemolysis on blood

Since Endo Agar selects for Gram negative (-) organisms, and differentiates for lactose, lactose += red colonies and surrounding medium, also coliforms produce a golden metallic green sheen, E. Coli is one example of a microorganism that could grow on Endo Agar.


How is it possible for an organism to grow on starch agar if it does not hydrolyze starch?

Starch agar is usually composed of nutrient agar with starch added. Organisms can grow on it w/o the use of starch because the media provides the necessary carbon and energy sources.
