Sellards & Sturm (Massachussels, 1919) who found it in 25 

 out of 31 cases of measles. It usually disappeared quickly after the 

 symptoms ceased. 



Seligmann & Wolf (Berlin), in 1919, by using the „coughing 

 method" demonstrated it in 30 out of 94 cases of influenza, in 22 

 out of 57 cases of measles, in 20 out of 44 cases of whooping- 

 cough, in 12 out of 52 cases of tuberculosis, in 2 out of 21 cases 

 of diphtheria, but in no case out of 31 scarlatina patients and 16 

 healthy persons. 



Pilot & Pearlman (Chicago) from April to July 1920 made 

 cultivations from the excised tonsils and adenoids of 155 persons 

 and found Pfeiffer's bacillus in the tonsils 62 times and in Ihe 

 adenoids 47 times. 



Stillman (New York) in the winter of 1920—21 when there 

 were only a few cases of typical influenza in the town, cultivated 

 Pfeiffer's bacillus from the throat and other places in 30 out of 

 35 patients with lobar pneumonia. 



Thai on the whole Pfeiffer's bacillus is principally met 

 with in the beginning of the disease is maintained by 

 Neueeld & Papamarku, Olsen and many others. Some Italian 

 authors have found this to a particularly marked extent. 



Piras and Gosio (1) assert that in order to demonstrate Pfeif- 

 fer's bacillus it is important to make the examination in the first 

 12—15 hours of the illness. 



That this provision is not always necessary, is evident at any 

 rate from the paper cited of Opie & others (p. 37). 



The occurrence of the bacillus in influenza in the blood 

 and various internal organs apart from the respiratory tract 

 is reported, in addition to the already mentioned authors 

 (Paltaue (1), Leiciitentritt; Messerschmidt, Hundeshagen, 

 & Sciieer, Kraus & Kantor), amongst others by the fol- 

 lowing: , 



Courmont, Durand, & Dufourt found Pfeiffer's bacillus by 

 cultivation of the blood post mortem in 4 cases (twice in pure cul- 

 ture and twice associated with Streptococci); they did not find it 

 however in kidney, spleen or liver, nor in 86 blood tests taken 

 in vivo. 



v. Hoesslin; Dick & Murray, and Spooner, Scott, & Heath 

 each report finding Pfeiffer's bacillus twice in the blood; the two 

 last-named groups of authors each examined the blood of 80 pa- 

 tients, in vivo and post mortem respectively.
