Abstract
An automated, quantitative microhemagglutination assay for antibodies to
Treponema pallidum
was developed by using
T. pallidum
-sensitized erythrocytes and an automatic serial-dilution instrument. Reactivity was found in sera from 54 rabbits and 6 chimpanzees infected with
T. pallidum.
Reactivity was also found in sera from animals infected with
T. pertenue, T. carateum
, and
T. cuniculi
. No reactivity was found in sera from 75 normal rabbits or from 129 rabbits immunized with cultivatable treponemes or a variety of other bacteria. In approximately 3 min, 13 twofold serial dilutions of each of 8 preabsorbed sera and the addition of sensitized erythrocytes to each dilution were accomplished automatically. The automated assay can serve as a research tool in quantitating antibodies to pathogenic treponemes, and evaluation of its clinical usefulness seems warranted.
