Deoxyribonuclease B (DNAse B) is one of several extracellular enzymes produced by group A beta-hemolytic streptococci. Since DNAse B is produced extensively by group A serotypes and is not produced in significant amounts by other serological groups (C and G), anti-DNAse B is a reliable streptococcal antibody test for both skin and throat infections.
Applications
Used in the formulation of anti-DNAse B assays which are used in the diagnosis of group A Streptococcal based illnesses.
