324 MICROBIOLOGY 



bacilli have been reported by Van Ermengem, 2 Hoist, 3 Poels 

 and Dhont, 4 and Basenau. 5 Schom 6 found B. Gartner in an 

 outbreak of disease among rats and also found it in the living 

 normal rats. He concludes that the rat is the "carrier" of 

 this bacillus. Trautman 7 had previously reported this organ- 

 ism as the cause of a disease in rats. 



Bacillus icteroides Sanarelli. 8 This organism was discov- 

 ered by Sanarelli in the blood of yellow fever patients and was 

 thought by him to be the cause of that disease. Reed and 

 Carroll 9 showed that it was closely related to if not identical 

 with B. suipestifer. Later investigations showed that it bears 

 no specific etiological relation to yellow fever. 



Bacillus typhi murium Loeffler. 10 This organism was dis- 

 covered by Loeffler to be the cause of a fatal epizootic among 

 field mice. Smith pointed out that it belonged to the B. sui- 

 pestifer group of bacteria. 



B. morbificans bovis Basenau. 11 Basenau discovered this 

 organism in meat. It seems to be identical with or at. least 

 very closely related to B. enteritidis. 



B. paracolon Gwyn. In 1898 Gwyn 12 reported the dis- 

 covery of a bacillus in the blood of a patient who presented all 

 the symptoms of typhoid fever but who did not give the usual 

 blood reaction. He designated it as "paracolon." 



Bacillus Gushing. Gushing 13 isolated this bacillus from
