title: [Toxicity of S-, R- and M-forms of enteropathogenic E. coli O149:K91:H10].
abstract: Toxicity of freeze-dried lysates of the organism for unweaned mice (3-4 days old) increased in the order:smooth-mucoid-rough. The toxicity was neutralized by mixing the toxin with immune serum of group O149. All toxins of the smooth, rough and mucoid variants of the Escherichia coli strain possessed hypersensitivity, skin necrosis, abortion and diarrhoea factors, which could be partly or completely neutralized by binding with homologous immune serum.
