The above results may be summarized as follows: 
The organisms studied fall into fifteen groups by reason of certain 
differences in their power to ferment carbohydrates and alcohol mannite. 
The first group, or “A” type, is represented by the ‘‘ Shiga,” which ferments only 
dextrose; the second, or “B” type, by the culture “ Port Arthur,” which was 
isolated by Dr. Oshida from Russian military officers suffering from acute epi- 
demic dysentery. It attacks maltose in addition to dextrose, producing acid. 
The third, or “C” type, is represented by the culture which I have called 
“Yalu.” It was isolated from a few dysentery patients among sailors of the 
Japanese squadron cruising on the Yalu Sea. The type ferments saccharose in 
addition to dextrose. 
The fourth, or “D” type, is the culture * Rio-yang II,” which was isolated after 
the siege of Rio-yang from a patient near that place in Manchuria. It is capable 
of fermenting both dextrose and dextrin. 
The fifth, or “E” type, is designated as “Korea I” and ferments both dextrose 
and lactose. It was isolated by naval fleet surgeon Dr. Momose from a patient 
at Chin-Kai-wang, Korea. 
The sixth, or “F” type, is represented by the culture “ Wakayama I,” which 
I isolated in an epidemic at Wakayama (situated about 20 miles distant from 
Osaka). The organism attacks saccharose, dextrin, and lactose in addition to 
dextrose. 
The seventh, or “G” type, is represented by the culture “ Tokyo I,” which 
ferments dextrose and alcohol-mannite. This type was first isolated by Flexner, 
and afterwards was classified by Hiss as Type IT and by Park, Collins, and 
Goodwin as Type III. The strain with which my experiments were made was 
obtained in Japan by Kawaguchi and Tsuchiya, but at the time of its isolation 
it was thought to be identical with the “Shiga” type. Later I studied its exact 
characters and afterwards Dr. Futaki (31) (1903), Nakajo (32), and Tsuchiya 
(33) (1904) also reported upon them. This type is identical with the “Y” type 
of Hiss and Russel. 
The eighth, or “H” type, is represented by “ Korea II,” which differs from the 
type “G” in fermenting saccharose. This organism is identical with the “Strong” 
type of Hiss (first isolated by Strong). 
The ninth, or “I” type, is illustrated by the culture “ Rio-yang II,” which, 
besides dextrose, also ferments mannite, maltose, and saccharose. 
The tenth, or “J” type, is represented by the culture “ Baltic II.” This organ- 
ism ferments not only dextrose and mannite, but also dextrin. This type was 
studied by military surgeon Dr. Oshida; it was isolated from captured Russian 
naval officers suffering from dysentery on board the Baltic fleet after the battle 
of the Japanese Sea and was sent by him to me. 
I am justified in considering it as a strain having a different source from those 
of the same type isolated in Japan, since the Russian patient from which it was 
obtained had not been in Japan nor in communication with that country. 
The eleventh, or “K” type, is represented by the culture “ Tokyo III,” which 
differs from type “J” only by the fact that it ferments saccharose. 
The twelfth, or “L” type, is represented by the culture “ Yamaguchi,” which 
differs from the “O” type only in not fermenting lactose. 
The thirteenth, or “M” type, is represented by the culture “ Tokyo IV,” which, 
besides dextrose and mannite, also ferments maltose and lactose. The fermenta- 
tion, except in the case of lactose, is usually rapid, being distinctly manifest in 
twenty-four to forty-eight hours.
