ACHROMOBACTER DEL r CATULUM (Jordan) Bergey et al. 

 (See also Achromobacter hyalinum . ) 



Insect concerned: The Colorado potato beetle, Leptino - 

 tarsa decemlineata . 



Steinhaus (19^1) isolated this bacterium from the 

 alimentary tract of the Colorado potato beetle. See Ber-

Achromobacter euryd 1 ce (White) Bergey et al. 

 (See also Bacillus alvei and Bacillus pluton . ) 



Insect concerned: The honey bee, Apis me 11 if era . 



White (1912) named this organism Bacterium eurydice . 

 Bergey et al. (see Bergey's Manual, 2d ed. , 1935, P« 170; 

 see also 5th ed. , 1939, P« 517), renamed it Achromobacter 

 eurydice . 



White was unable to produce European foulbrood in bees 

 with Bacterium eurydice , although it is apparently a 

 secondary invader in the disease. Burnside, (193*0 found 

 that Bacillus alvei , the recognized causative agent of 

 European foulbrood, is capable of morphologic, cultural, 

 and biologic transformation, and he further states that 

 Bacillus alvei "is also capable of stabilization, at least 

 temporarily, as a sporogenic rod, an asporogenic rod 

 resembling Bacterium eurydice, or a coccoid resembling
