CORYNEBACTER I UM BLATELLAE Glaser 

 Insect concerned: The German roach, Blattella germanica . 



In the fat "body of the cockroach are found hacteriocytes, 

 the cytoplasms of which are filled with microorganisms. 

 Glaser (1930b) claims to have cultivated these organisms 

 from the German roach on artificial media, and gave the 

 name Corynehacterium "blattellae to the diphtheroidal forms 

 he isolated. Earlier (1930a), he reported on a similar 

 organism which he isolated from the American roach, ' 

 Periplaneta americana (see Corynehacterium periplanetae 

 var. americana ) . Gier (1936) obtained only negative 

 results in his attempts to cultivate the ""bacteroids" 

 from roaches. 



For a "brief description of this organism see Bergey's 

 Manual (5th ed. , page 798).
