GENUS STREPTOCOCCUS 205 



ever, to determine the species of these streptococci. Gilruth 4 

 mentions a streptococcus as the cause of a very serious mas- 

 titis of cows. He found that while it is generally a chronic 

 disease, occasionally a very acute state of inflammation is 

 seen. He states that cases are not altogether rare where death 

 from generalized septicemia has followed the very acute form 

 of the disease. 



OTHER STREPTOCOCCI. 



The literature contains many statements concerning the 

 presence of streptococci in various local lesions and also asso- 

 ciated with the lesions in certain infectious diseases. We have 

 found streptococci repeatedly in the lesions of dog distemper 

 but have not been able to find them in all cases. The descrip- 

 tions that have been published of streptococci isolated from 

 morbid tissues have, as a rule, not been sufficiently complete to 

 differentiate them or to justify naming them as new species. 

 At present, therefore, we can only say that streptococci have 

 been found in a great variety of lesions. It is possible that 

 further investigations will show that certain of these bear a 

 causal relation to the morbid tissues in which they were found.
