Excerpt from The Journal of Hygiene, 1912, Vol. 11 The present paper contains the results of an enquiry into the differentiation of certain organisms of varying source, which present characters more or less closely allied to those of the mannite or Flexner type of the dysentery bacillus. The non-mannite type, first discovered by Shiga in 1898, as the cause of certain forms of bacillary dysentery in Japan, and later by Kruse in 1901, as the cause of epidemic dysentery in Rhenish West phalia, has been shown to remain remarkably true to type, and our present cultural and serological methods amply suffice to separate it off clearly from the mannite or Flexner type. We are, in fact, justified in speaking of the Shiga bacillus of Dysentery. It is other wise with the mannite-fermenting type. The work of the last ten years in various countries has elicited the fact that the bacillus discovered by Flexner in Manila in 1901 must be regarded merely as a type of a group comprising an ever-increasing number of strains differing in certain properties from the type-strain, and from each other. The members, or sub-types, of the mannite-fermenting group, which have been most thoroughly investigated are Flexner's bacillus, the Y bacillus of Hiss and Russell discovered in 1904, and the bacillus of Strong.
