MICROBES OF MALIGNANT ANTHRAX

Roux and Yersin, isolated from the fauces of the healthy as also of in- 

 llamed throat, there occur bacilli which form very pronounced clubs 

 and threads with segregated protoplasm with terminal knobs, but which 

 in cultural respects differ from the pseudo-diphtheria and the true 

 diphtheria bacilli. 



Thus, from milk taken directly from the teats of the cow I have

isolated a bacillus forming exquisite clubs [sec Fig. 124), but which in 

 cultural respects markedly differs from the diphtheria bacillus ; it forms 

 on Agar yellow round colonics and grows much faster than the diph- 

 theria bacillus, besides being non-pathogenic. Similarly from putrid 

 beef I have isolated bacilli which in morphological respects bear a great 

 resemblance (j'tv Fig. 125) to the diphtheria bacillus but do not grow 

 at 37^ C.
