[Characteristic of endotoxin (and haemolysin) for S-, R- and M-forms of the enteropathogenic "E. coli" (author's transl)].
Endotoxins of E. Coli O 149, IN S-, R- and M-forms, were examined in comparison. Gas chromatography showed only quantitative differences in the amount of volatile fatty acids. Electrophoresis of immunsera and bacteriostatic potency of sera, showed the immunogenicity of those 3 endotoxins, in sequence: S leads to R leads to M. Endotoxin of enteropathogenic E. coli O 149 provokes haemorrhagic effects in bones marrow of mice. Endotoxin influences the reticulo-endothelial system (mobilization of immunocytes). Endotoxin does not provoke any changes in "ligated loop tests'.
