Bacter i um mon achae von Tubeuf 

 (See Bacillus B and Bacillus monachae . ) 



Insect concerned: The nun moth, Lymantr ia monacha . 



Von Tubeuf (1892a and "b) isolated this organism from 

 the intestinal tract of the nun moth, considering it to 

 be the causative agent of the "wilt" disease (Wipfelkrank- 

 heit). Later von Tubeuf (1911) reversed his opinion on 

 the specific cause of the disease and concluded that it 

 was due to a variety of intestinal bacteria becoming 

 dominant. Since, Wahl (1909 to 1912) has shown that the 

 disease is due to a virus. 



Eckstein (I89M considered Bacterium monachae , Bacillus 

 E. of Hofmann (1891), and Bacillus monachae to be identi- 

 cal organisms.
