scribed a serious outbreak of foot rot and erysipelatous in- 

 flammation in the limbs of cattle due to this organism. 



STREPTOCOCCUS EQUI SCHUTZ. 



Synonyms. Streptococcus coryzae contagiosae equormn 

 Eisenberg. 



Place in nature. This streptococcus was described by 

 Schiitz, 2 Sand and Jensen, 3 Poels 4 and Lupke 5 independently 

 as the cause of strangles. It is generally accepted that the 

 organism described by these different authors belongs to the 

 same species. This streptococcus can not be differentiated with 

 certainty from 8. pyogenes. 



STREPTOCOCCUS OF APOPLECTIFORM SEPTICEMIA IN FOWLS 

 NORGAARD AND MOHLER. 



Place in nature. Norgaard and Mohler c described briefly 

 a streptococcus which appeared to be the cause of a fatal dis- 

 ease in chickens designated by them as apoplectiform septi- 

 cemia. It has been found in one outbreak in New York State 

 where nearly every fowl in the flock died. 



Morphology. A streptococcus composed of chains of 

 variable length. Individual chains vary from 0.6 to 0.8 mi- 

 crons in diameter. In tissues they appear as short chains in 

 from 2 to 8 segments, while in bouillon they are much longer. 

 Irregular segments are occasionally observed. Mohler states 

 that the division sometimes occurs longitudinally to the axis 

 of the chain and sometimes a perpendicular division occurs in 

 the same individual. 



Staining 1 . The streptococcus stains readily with aniline 

 dyes and also by Gram's and Gram Weigert's methods. 



Cultivation. This streptococcus is an aerobe and a facul-
