Determination by enzyme-linked immunosorbent assay of immunoglobulin G (IgG), IgM, and IgA to Brucella melitensis major outer membrane proteins and whole-cell heat-killed antigens in sera of patients with brucellosis.
An enzyme-linked immunosorbent assay was used to compare Brucella melitensis major outer membrane proteins (MOMP) and whole-cell heat-killed antigens (HK) in measuring antibrucella immunoglobulin G (IgG), IgM, and IgA in sera of brucellosis patients and controls. Antibodies to MOMP were generally similar to those against HK, and the correlation coefficients between the two antigens and IgG, IgM, and IgA in patients varied between 0.73 and 0.94. Both antigens are comparably suitable in detecting antibrucella immunoglobulin isotypes for the serologic diagnosis of patients with brucellosis, with high (greater than or equal to 95%) sensitivity and specificity.
