This toxic protein accounted for the major portion of the toxicity of whole organism. Immunological and chemical data suggest that the toxic protein is the protein component of the Boivin antigen. The lipopolysaccharide endotoxins of the strains examined were relatively non-toxic as compared with the lipopolysaccharides from other Gramnegative bacteria, though in other biological and chemical properties they resembled the general class., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-21-1-191
