This toxin contains highly antigenic effects which causes it to produce the antibody anti-streptolysin O. Clinically, the presence of these antibodies can indicate a recent Group A streptococcal infection. Streptolysin O is also known to facilitate apoptosis in Keratinocytes. See more Streptolysins are two hemolytic exotoxins from Streptococcus. Types include streptolysin O (SLO; slo), which is oxygen-labile, and streptolysin S (SLS; sagA), which is oxygen-stable. SLO is part of the See more Streptolysin S (SLS; sagA), is a cytolytic virulence factor which is a member of the thiazole/oxadole-modified microcin (TOMM) family. This cytolysin is a post-translationally modified See more Streptolysin O (SLO; slo), is a bacterial toxin that has four protein domains which is known to make the plasma membranes in animal cells permeable. It does this by creating pore complexes within the membrane by first binding a monomer to the cholesterol … See more WebMay 15, 2005 · Initially, antistreptolysin O (ASO) titers should be obtained. If the test result is positive, it confirms a recent invasive streptococcal infection. The antibody response usually peaks at about...

WebJul 24, 2024 · Antistreptolysin O (ASO) is an antibody targeted against streptolysin O, a toxic enzyme produced by group A Streptococcus bacteria. ASO and anti-DNase B are the most common of several antibodies that are produced by the body’s immune system in response to a strep infection with group A Streptococcus.This test measures the amount … WebStreptolysin O is a sulfhydryl-activated toxin produced by groups A, C and G of streptococci. It is an oxygen-labile hemolytic enzyme capable of causing lysis in animal cells, particularly white and red blood cells. It does so by binding to membrane cholesterol, where it polymerises to form a transmembrane channel. Product Details Target Species WebJul 1, 2005 · Streptolysin O (SLO) was the designation assigned to the oxygen-dependent labile hemolysin found in cell-free culture fluids during the growth of GAS in liquid cultures. A second cell-associated hemolysin was named streptolysin S (SLS), because its activity was stable to atmospheric oxygen. rrr movie online ticket booking
