90 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Gelatin is not liquefied. In most cases, milk was found to be the best 

 culture-medium. 



The authors differentiate two types, A and B. In type A, 2 ■ 7-3 ' 7 p.c. 

 of lactic acid is produced in milk, this lactic acid being of the inactive 

 modification. The protoplasm is stained homogeneously by Loffler's 

 methylen-blne or Neisser's stain. Bacilli of type B so stained show 

 deeply staining granules, and in milk 1 ■ 2-1 ■ 6 p.c. of laevolactic acid is 

 formed. 



Bacillus septictemise anserum exsudativse.* — P. Frosch and K. 

 Bierbaum isolated this organism from the heart-blood and peritoneal fluid 

 of two geese that had died of goose-plague. It possesses many points 

 of resemblance to the B. influenzse Pfeiffer. It is a small bacillus 

 0'5-l # 5fi long, 0'b fj. in breadth. It takes up the ordinary stains. 

 but is Gram-negative. It stains best with carbol-fuchsin. It is non- 

 motile, and does not form spores. When first isolated it grows only 

 upon media containing blood, but after cultivation for about twenty 

 generations it will grow upon alkaline agar and some other media. 

 The optimum temperature is 37° C. Cultures possess low vitality and 

 are prone to die out. It is assigned to the group of pseudo-influenza 

 bacilli.
