[Serotype 185 and E. coli O115 - two distinct bioseropathotypes (author's transl)].

E. coli O115 strain 27w and TRABULSI's serotype 185 have been subjected by us to comparing examinations of the serological behaviour of their cell wall and their protoplasmatic antigens, of their biochemical and cultural behaviour and their pathogenicity for the mucous membranes of guinea-pigs. As a result of this inquiry it was found, that E. coli O115 27w and the dysentery-provoking serotype 185 are biological distinct bacteria which only share a minor cross relationship of their O-antigens, and which should not be classified together.
