Blood agar plates allow for the growth of fastidious organisms and the differentiation of three hemolytic activities.
An agar plate is a Petri dish that contains a growth medium (typically agar plus nutrients) used to culture microorganisms or small plants like the moss Physcomitrella patens. Selective growth compounds may also be added to the media, such as antibiotics. Blood agar plate (BAP). Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a concentration of 5–10%. BAPs are enriched, differential media used to isolate fastidious organisms and detect hemolytic activity. Chocolate agar. Chocolate agar (CHOC) is a type of blood agar plate in which the blood cells have been lysed by heating the cells to 56 °C. It is used for growing fastidious respiratory bacteria, such as Haemophilus influenzae. No chocolate is actually contained in the plate; it is named for the coloration only. Blood agar plate (BAP). Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a concentration of 5–10%. BAPs are enriched, differential media used to isolate fastidious organisms and detect hemolytic activity. 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 o … rganisms that would not readily grow on media that lack red blood cells. The erythrocytes in blood agar serve two purposes: as a source of food for the growing bacteria and as a diagnostic indicator for certain types of bacteria. There are two types of red blood cell hemolysis, referred to as alpha (or complete) hemolysis and beta (or incomplete) hemolysis. The presence of alpha or beta hemolysis on a blood agar plate is diagnostic for certain types of bacteria Blood Agar Plates (BAP) (Atlas p. 49). Blood agar is actually a couple of related media, all of which are rich formulations containing peptones, yeast extracts, liver or heart extracts (depending on the medium), and blood. The blood is usually sheep's red blood cells (RBC), though horses and other species may be used. One such pathogen that BAP can detect is Streptococcus pyogenes which causes a number of diseases including strep throat, rheumatic fever, and necrotizing fascitis. Purpose: blood agar plates allow for the growth of fastidious organisms and the differentiation of three hemolytic activities. Horse blood agar (HBA) is a type of blood enriched microbiological culture media. As it is enriched, it allows the growth of certain fastidious bacteria, and allows indication … of haemolytic activity in these bacterial cultures. The erythrocytes in blood agar serve two purposes: as a source of food for the growing bacteria and as a diagnostic indicator for certain types of bacteria. There are two types of red blood cell hemolysis, referred to as alpha (or complete) hemolysis and beta (or incomplete) hemolysis. The presence of alpha or beta hemolysis on a blood agar plate is diagnostic for certain types of bacteria Blood agar contains general nutrients and 5% sheep blood. It is useful for cultivating fastidious organisms and for determining the hemolytic capabilities of an organism. Some bacteria produce exoenzymes that lyse red blood cells and degrade hemoglobin; these are called hemolysins.  Blood agar is a bright red and opaque medium that is used to accelerate the growth of medically-important fastidious bacteria. Blood agar is made of nutrients and a little bit of sheep blood. Blood agar is used to for cultivating fastidious organisms and for determining the hemolytic capabilities of an organism. Posted on. (Answer #1). Agar or agar plate is nothing but a growth media composed of certain nutrients that allow the growth of microbial organisms needed for scientific experiments. A Blood Agar is a special and more complex kind of agar that is composed of the requisite rich nutrients along with blood.
