The relationship and significance of antibody titres as determined by various serological methods in glandular and ocular toxoplasmosis.
Three types of antibody curve have been demonstrated by testing sera during the course of acquired toxoplasmosis by six different techniques. These three types are due to cell-wall antibody, (demonstrated by four of the techniques), to antibody to soluble antigen, and to IgM antibody to the cell wall. These findings have been supported by absorption experiments. A scheme is presented for testing single sera by two or three different tests to indicate the stage and duration of the infection.
