Antigens of Streptococcus mutans implicated in virulence--production of antibodies.

ABSTRACT

The present studies assayed antibody activities in serum and saliva of animals immunized by different routes, with cells of S. mutans or cell-free preparations containing GTF, FTF, LTA and/or dextranase synthesized by S. mutans. The results show that the type of immunogenic preparation and the route of its administration can elicit different antibody response and may in part explain the disparity of results achieved by different investigators. The results further emphasize the need to use standardized preparations and carefully described protocols for vaccination.
