SOME DISEASES NOT PREVIOUSLY REFERRED TO, WITH 

 A DISCUSSION OF THEIR CAUSATION MICRO- 

 ORGANISMS OF SKIN AND MUCOUS -MEMBRANES 



APPENDICITIS. The following Table * shows the usual kinds and 

 relative frequency of the infections in appendicitis : 



It is not improbable that in a still greater percentage of cases 

 a mixture of organisms is present at first, the Bacillus coli subse- 

 quently crowding out the other forms. The Bacillus proteus, 

 B. pyocyaneus, and B. Welchii also occasionally occur. 



Castellani 2 describes a bacillus, pathogenic to guinea-pigs, 

 isolated from a case of gangrenous appendicitis. Morphologically 

 it resembled the Shiga-Kruse dysentery bacillus, and was non- 

 motile, produced acid and gas in glucose and maltose and curdled 

 milk, but did not ferment mannite, lactose, and sucrose. 



BEBI-BEBI. Various observers have attempted to cultivate a 

 micro-organism in this disease. Cocci have been described by 

 Pekelharing and Winkler, Hunter, Okata and Kokubo, a sporing 

 bacillus by Rost, and Hamilton Wright suggests that the disease 

 is due to an intoxication, the result of a gastro- duodenal infection
