BACTERIOLOGY OF MEAT AND MEAT PRODUCTS 123 



found bacteria in 72 cases. Both aerobic (42 strains) and 

 anaerobic bacilli (30 strains) were isolated. The aerobic bacilli 

 were B. coli communis, B. lactis aerogenes, Streptococcus acidi 

 lactici, B. mesentericus ', B. fluorescens non-liquefaciens, Diplococcus 

 pneumoniae and B. suipestifer. The anaerobic bacilli were chiefly 

 of the butyric acid group but the varieties were not accurately 

 defined. 



Bierotti and Machida 1 employed a modified Conradi method 

 and obtained very similar results. They examined 54 organs 

 from II quite healthy animals and found bacilli in 32. 



Their results and those of Conradi are grouped together in 

 the following table.

Horn 2 examined oxen slaughtered in the Leipzig Slaughter 

 House, using a modified Conradi method (enrichment method) 

 and also direct examination. He found, as might be expected, 

 that the number of bacteria in the muscles varied with the time 

 since slaughter. His results are briefly summarised in the 

 following table.
