Abstract
Serum concentrations of IgM and IgG antibodies in patients with M. pneumoniae pneumonia were determined by enzyme-linked immunosorbent assay. Analysis of serum specimens by treatment with protein A, followed by fractionation on sucrose density gradient, revealed for the 1st time the presence of rheumatoid factor in M. pneumoniae pneumonia with a remarkably high frequency. Development and persistence of the rheumatoid factor during the clinical course of this disease were also examined.This publication has 0 references indexed in Scilit:
