[The effect of somatic antigen from Bacillus subtilis on migration of mouse macrophages].

The migration of mice peritoneal macrophages has been studied on agar plates. The migration of the macrophages from mice treated by the intra peritoneal route by a somatic antigen of Bacillus subtilis, was 37% less than the migration of the macrophage from control mice. The presence of the antigen in the gel did not modify the migration of macrophages in either treated or control mice. This confirms the non specific character of the activity of this antigen.
