BAC I LLUS ALBOLACT \ S Migula 



Insect concerned: The American roach, Periplaneta ameri - 

 cana . 



This organism was first isolated from "boiled milk. 

 Hatcher (1939) isolated it from the feces of the American 

 cockroach, Periplaneta americana . 



According to Bergey's Manual (5th ed. , p. 667) this 

 organism agrees in its morphologic and cultural charac- 

 teristics with Bacillus cereus and is considered to he a 

 variety of the latter. It differs from Bacillus cereus 

 "by the acid fermentation of milk.

and Streptococcus apis . ) 



Insects concerned: The honey "bee, Apis mellifera , and 

 Polia oleracea . 



Cheshire and Cheyne (1885) first described Bacillus 

 alvei as the cause of the "brood disease now known as 

 European fouTbrood. The etiology of this disease, which 

 is of great economic importance, has "been the subject of 

 considerable controversy. Maassen (1907) "believed that 

 it is caused "by either Streptococcus apis or Bacillus 

 alvei . White (1912, 1920a, 1920b) was unable to produce 

 typical European fouTbrood with Bacillus alvei , Strepto - 

 coccus apis or Bacterium (now Achromobacter ) eurydice and 

 concluded that a new species, Bacillus pluton , was the 

 real cause. Burns ide (192*0 attempted to bring some order 

 out of the confusion. He found that "Bacillus alvei is
