Alpha hemolysis refers to the partial hemolysis of red blood cells shown by the greenish discoloration surrounding the bacterial colony in the blood agar. The main difference between alpha and beta hemolysis is that alpha hemolysis is involved in partial hemolysis associated with the reduction of hemoglobin in red blood cells whereas beta hemolysis is involved in the complete hemolysis of red blood cells that surround the colony. On prolonged incubation, many alpha hemolytic organisms will begin to appear more clear, but if the surrounding medium contains any shades of brown or green the “hemolysis” is still considered “alpha.”. – Own work (CC BY-SA 3.0) via Commons Wikimedia, Lakna, a graduate in Molecular Biology & Biochemistry, is a Molecular Biologist and has a broad and keen interest in the discovery of nature related things, Difference Between Alpha and Beta Hemolysis, What are the Similarities Between Alpha and Beta Hemolysis, What is the Difference Between Alpha and Beta Hemolysis, What is the Difference Between E coli and Salmonella.

Alpha hemolysis is characteristic of Streptococcus pneumonia and so can be used as a diagnostic feature in the identification of the bacterial strain. There are three types of hemolysis, designated alpha, beta and gamma. A hemolytic reaction, which is where alpha and beta hemolytic strep get their names from, is a reference to how blood cells appear to burst in response to a particular disease. Beta Hemolysis: Beta hemolysis is a type of complete hemolysis of red blood cells that surround the colony. This is sometimes called green hemolysis because of the color change in the agar. Alpha Hemolysis: Alpha hemolysis is also known as partial hemolysis or green hemolysis. The β-hemolysis pattern results in the media displaying clear halos around bacterial colonies.

In alpha thalassemia, there is a decrease in the number of alpha globin chains whereas in beta-thalassemia it is the number of beta globin chains that goes down. Can be alpha, beta, or gamma hemolytic and are normal inhabitants of the human intestinal tract. Alpha and beta hemolysis are two types of hemolysis that occur by the infection of different Streptococcus species. Beta Hemolysis: The width of the zone is 2-4 mm in beta hemolysis. Beta hemolysis: Beta-hemolytic bacteria cause complete lysis of red blood cells, hence they form clear zone around their colonies. Alpha hemolysis 2. FIG.

Alpha particles are made of four nucleons. Alpha-, beta- and gamma-cyclodextrins are cyclic hexamers, heptamers, and octamers of glucose, respectively, and thus are hydrophilic; nevertheless, they have the ability to solubilize lipids through the formation of molecular inclusion complexes. Four types of hemolysis are produced in sheep blood agar by Streptococci namely; alpha (α) hemolysis, beta (β) hemolysis, gamma (γ) hemolysis, and alpha prime or wide zone alpha hemolysis. This is the key differencebetween alpha hemolysis and beta hemolysis. Some Streptococcus pyogenes species produce an oxygen-stable hemolysin called Streptolysin S. Beta hemolysis is shown in figure 2. It is involved in the true or complete lysis of red blood cells. Explain the difference between alpha, beta and gamma hemolysis, and name the type of plate used to determine if a strain of bacteria is hemolytic or not. Streptokock är en typ av gram-positiva bakterier som förekommer som kluster eller korta kedjor. Beta hemolysis refers to the complete breakdown of red blood cells, demonstrated by a clear zone surrounding the bacterial colony in the blood agar. Alpha refers to partial hemolysis with a green coloration (from production of an unidentified product of hemoglobin) seen around the colonies; beta refers to complete clearing (figure 5) and gamma means there is no lysis. * Beta hemolysis means that the bacteria’s hemolytic enzymes completely beak down the blood cells.
