Caption:
This historic 1965 photograph, depicted a laboratory technician, as he was employing a microtechnique, during an analysis, which would test for the suspected presence of antistreptolysin O (ASO or ASLO), in a patient’s serum samples. ASO is an antibody, produced by a person infected with Lancefield group A streptococci bacteria, in response to the bacterial production of an enzyme, i.e., antigen, streptolysin O. This enzyme is one of two, produced by this pathogen, which is involved in the hemolytic reaction seen in specific streptococcal infections. Hemolysis is the physical breakdown of red blood cells (RBCs).
