The ability of bacterial colonies to induce hemolysis when grown on blood agar is used to classify certain microorganisms . This is particularly useful in classifying Streptococcus streptococcal species. A substance that causes hemolysis is a hemolysin . Types of hemolysis Alpha When alpha hemolysishemolysis is present, the agar under the colony is dark and greenish. Streptococcus pneumoniae and a group of oral streptococci Streptococcus viridans Streptococcus viridans or viridans streptococci display alpha hemolysis. This is sometimes called green hemolysis because of the color change in the agar. Other synonymous terms are incomplete hemolysis and partial hemolysis . Alpha hemolysis is caused by hydrogen peroxide produced by the bacterium, oxidizing hemoglobin to green methemoglobin . Beta Beta hemolysishemolysis , sometimes called complete hemolysis , is a complete lysis of red cells in the media around and under the colonies the area appears lightened yellow and transparent. Streptolysin, an exotoxin, is the enzyme produced by the bacteria which causes the complete lysis of red blood cells. There are two ... results in hemolysis under the surface of blood agar.

Hemosiderinuria syn. haemosiderinuria , brown urine , occurs with chronic intravascular hemolysis , in which hemoglobin is released from RBCs into the bloodstream in excess of the binding capacity of haptoglobin . The excess hemoglobin is filtered by the kidney and reabsorbed in the proximal tubule, where the iron portion is removed and stored in ferritin or hemosiderin . The tubule cells of the proximal tubule slough off with the hemosiderin and are excreted into the urine, producing a brownish color. It is usually seen 3 4 days after the onset of hemolytic conditions. Hemoglobinuria is another indicator of intravascular hemolysis, but disappears more quickly than hemosiderin, which can remain in the urine for several weeks therefore, hemosiderinuria is a better marker for intravascular hemolysis.

Camille Delezenne 10 June 1868 7 July 1932 was a French physician and biologist born in Genech , a town in the department of Nord French department Nord . He studied medicine in Lille , obtaining his hospital internship in 1890. In 1892 he supported his doctorate with a dissertation on Parapneumonic effusion parapneumonic pleurisy . Afterwards he undertook experiments on blood circulation at the Wertheimer laboratory in Lille. During this time period, he also served as mayor of Genech 1893 95 . In 1896 he was appointed associate professor of physiology at the University of Montpellier . At H don s laboratory he conducted systematic investigations of blood coagulation in vertebrates, demonstrating the hepatic origin of antithrombin and describing the blood coagulation system of birds. In 1900 he relocated to Paris , where he worked as a lecturer in the laboratory of physiological chemistry at the Ecole des Hautes Etudes . With assistance from Emile Duclaux 1840 1904 and Elie Metchnikoff 1845 1916 , he was appointed head of the physiology laboratory at the Pasteur Institute , where his primary focus is research of enzymes , venoms and toxins. In 1902 he demonstated a link between the action of enterokinase in mobilizing pancreas pancreatic digestive enzymes and the phenomena of Hemolysis microbiology hemolysis . In 1902 Delezenne became a member of the Soci t de biologie , in 1903 he was co founder of the Bulletin de l Institut Pasteur with Am d e Borrel 1867 1936 , F lix Mesnil 1868 1938 , Gabriel Bertrand 1867 1962 , Alexandre Besredka 1870 1940 and Auguste Charles Marie 1864 1935 , and in 1910 became a professor at the Pasteur Institute.

Reticulocytopenia can originate from congenital hemolytic anemia , especially when exacerbated by Parvovirus B19 infection. Can occur with Sickle Cell Anemia and Spherocytosis , where hemoglobin levels fall rapidly and the marrow cannot compensate, causing absence of reticulocytes. Reticulocytes are immature red blood cells . Hereditary spherocytosis causes hemolysis, which leads to reticulocytosis, not a decrease in reticulocytes.

Hemoglobinemia British Haemoglobinaemia is a medical condition in which there is an excess of hemoglobin in the blood plasma . This is an effect of intravascular hemolysis , in which hemoglobin separates from red blood cells, a form of anemia . Hemoglobinemia can be caused by intrinisic or extrinsic factors. When hemoglobinemia is internally caused, it is a result of recessive genetic defects that cause the red blood cells to lysis lyse , letting the hemoglobin spill out of the cell into the blood plasma. In externally caused hemoglobinemia, an outside attacker acts as an antibody against the red blood cells. This can cause the cells to be destroyed and their hemoglobin released.

Angioid streaks , also called Knapp streaks or Knapp striae are small breaks in Bruch s membrane , an elastic Tissue biology tissue containing membrane of the retina that can become calcified and crack. They were first described by Robert Walter Doyne in 1889 in a patient with retina l hemorrhages. A few years later, ophthalmologist Hermann Jakob Knapp called them angioid streaks because of their resemblance to blood vessels . From histopathology histopathological research in the 1930s, they were discovered to be caused by changes at the level of Bruch s Biological membrane membrane . Presently, it is believed that its pathology may be a combination of elastic degeneration of Bruch s membrane, iron deposition in elastic fibers from hemolysis with secondary mineralization, and impaired nutrition due to stasis medicine stasis and small vessel Vascular occlusion occlusion . Angioid streaks are often associated with pseudoxanthoma elasticum PXE , but have been found to occur in conjunction with other disorders, including Paget s disease of bone Paget s disease , sickle cell anemia and Ehlers Danlos Syndrome .
