Duncan (1926) found Streptococcus haemolyticus (now 

 known as Streptococcus pyogenes ) to be inhibited by the 

 "bactericidal principle of the gut contents of Argas p_er- 

 sicus but not by that of Ornithodoros moubata .

During studies on the bacterial flora of normal insects, 

 Steinhaus (19^1) isolated a gram- positive coccus from a 

 long-horned grasshopper. The coccus at times appeared 

 almost as a very short rod. This characteristic is shared 

 by an organism which Bergey's Manual (1939; 5th ed. , page 

 258) describes under the name Micrococcus chersones ia ,
