Six strains of an organism associated with and apparently etiologically related to clinical cases of dysentery have been described. Five of these strains were isolated from cases in a town in Lancashire and the other from a case in Nigeria.These strains seem to be identical with the Newcastle dysentery bacillus described by Clayton and Warren except for the apparently constant difference in the action on mannite. Their relationship to the Flexner group of dysentery bacilli has been discussed.
