354 MICROBIOLOGY 



Schriitzler 2 speaks of its being the cause of meat poisoning. 

 Wesenberg 3 was able to isolate Bacillus proteus from decom- 

 posing meat which had caused serious illness in a large num- 

 ber of people. The poison may be a cleavage product result- 

 ing from the decomposition of the meat rather than a specific 

 toxin elaborated by this bacillus. 



Pathogenesis. Large doses injected into animals may 

 give rise to localized abscesses. In man it has been found 

 apparently as the etiological factor in cystitis and pyelone- 

 phritis.
