Biotin-avidin enzyme-linked immunosorbent assays (ELISA) were developed to study the appearance of free antibody of the IgM, G, and A classes of immune complexes (IC) containing those classes and of antigen in the serum and urine of mice with experimentally induced, disseminated histoplasmosis (histo) over a period ranging from 4 to 64 days after infection. Free IgM was detected 4 days after infection, remained at low levels, and disappeared on Day 64, whereas free IgG was first detected on Day 7 and rose to very high levels before declining on Day 64. Free IgA was detected only once, on Day 21. IC containing IgM were seen first on Day 4, remained at low levels, and became undetectable on Day 64. IC containing IgM were detected on Day 7, peaked on Day 14, and declined through Day 64. IC containing IgA wee seen at low levels on Days 7, 14, and 21. Estimation of total IgA levels, done by single radial immunodiffusion, showed a statistically significant decrease on Day 14, followed by a slightly significant increase on Days 21 and 30. Antigen was detected in as much as 80% of serum specimens and 100% of urine samples during the first 2 wk postinfection but rarely afterwards. We conclude that ELISA provides a highly sensitive way to study antibody, IC, and antigen in host body fluids during histo infection and that IgM and antigen detection can be very early indices of infection. Measurements of IC and total IgA seem to be of relatively less importance in detection of infection.
