Abstract
Summary
The role of lipoidal components of M. pneumoniae as antigenic determinants in vitro and in vivo is described.
Sera with TRI or CF titers with lipid antigen of 8 or greater are usually positive in the ID test, suggesting that this test might be used as a screening test for antibody to M. pneumoniae.
Since there is a high degree of correlation between TRI and CF titers when lipid extracts of M. pneumoniae are used as antigens, we feel that the lipid CF test will serve as an indicator of neutralizing antibody to M. pneumoniae.
