organism described by Shiga. The authors proved the etiologic 

 importance of this organism by experiments on animals and in 

 one case on man, and they were the first to isolate the bacillus 

 from the lymphatic glands. 



Shiga ^"^ reported extensive comparative studies between 

 various strains of the organisms, including the ones from Manila. 

 He credited the proof of the etiologic status of the organism to 

 Strong and Musgrave. 



Ohno'^ published an extensive study of all the available strains 

 of dysentery bacilli. He elaborated the classification into five 

 varieties. 



Bowman ^2 studied an epidemic of infantile dysentery in 

 Manila during August, 1907, from private patients selected from 

 our service. 



An organism of the typhoid-colon group with certain definite 

 distinctions was isolated from all these cases. This organism, 

 which Bowman designated as Bacillus "S," appeared to be the 

 causative agent in this epidemic. 



In cultural characters. Bacillus "S" is smaller and more delicate . 

 than B. coli or B. dysenterise, and it is actively motile. Toxic 

 properties and comparative agglutination tests seem to show 

 that it is distinct from other organisms of the group. However, 

 it is rather closely allied to Morgan No. 1, which was found by 

 Phalen and Ashburn in one epidemic of acute dysentery in and 

 around Manila. 



The prevalence and influence of the "Y" bacillus of Hiss and 

 RusseP* in infantile dysentery and further studied by Hiss^* 

 have been studied in the Philippine Islands by Whitmore. These 

 organisms are being assigned an important etiologic role in 

 colitis of children in Europe,'^ and should be studied partic- 

 ularly with reference to the benign dysenteries among children in 

 this country. 



Phalen and Kilbourne^* described an epidemic of bacillary 

 dysentery in Luzon. 



Bacteriologic studies of 8 cases at Camp McGrath showed 

 Morgan's No. 1 bacillus " in 5 cases, but no dysentery organ-
