Antibody response to peptidoglycan during staphylococcal infections. 1983

L J Wheat, and B J Wilkinson, and R B Kohler, and A C White

Levels of antibodies to peptidoglycan were measured by solid-phase radioimmunoassay in 76 patients with Staphylococcus aureus infections and 44 patients with infections caused by other bacteria. Levels of IgM antibodies to peptidoglycan were elevated in 24% of the patients with endocarditis or complicated bacteremia caused by S. aureus, 21% of those with serious infections caused by other gram-positive cocci, none of those with less serious infections caused by S. aureus or gram-negative bacilli, and 5% of the normal controls. Levels of IgG antibodies to peptidoglycan were elevated in 50% of the patients with endocarditis or complicated bacteremia caused by S. aureus, 3% of those with less severe infections caused by S. aureus, 17% of those with infections caused by other gram-positive cocci, 20% of those infections caused by gram-negative bacilli, and 5% of the normal controls.

D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D010457	Peptidoglycan	A structural polymer of the bacterial cell envelope consisting of sugars and amino acids which is responsible for both shape determination and cellular integrity under osmotic stress in virtually all bacteria.	Murein,Pseudomurein
D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.	Radioimmunoassays
D004696	Endocarditis	Inflammation of the inner lining of the heart (ENDOCARDIUM), the continuous membrane lining the four chambers and HEART VALVES. It is often caused by microorganisms including bacteria, viruses, fungi, and rickettsiae. Left untreated, endocarditis can damage heart valves and become life-threatening.
