Staphy lococcus aureus Rosenhach 



Insects and ticks concerned: The silkworm, Bombyx mori ; 

 the roaches Blattella germanica , and Periplaneta orientalis ; 

 the stahle fly, Stomoxys calci trans ; the hedhug, Cimex 

 lectularius ; the house fly, Musca domes tica ; the mosqui- 

 toes, Aedes cinereus , Aedes aegypti , and Anopheles hifur - 

 catus ; Rhodnius prolixus ; and the ticks, Argas persicus , 

 Argas reflexus ; and Ornithodoros moubata . 



Sawamura (1906) lists Micrococcus pyogenes aureus 

 f s cap hy loco ecus aureus 1 as heing experimentally pathogenic 

 to the silkworm. G-alli-Valerio (1907) refers to Staphylo - 

 coccus pyogenes aureus as having heen spread "by the tick, 

 Argas reflexus . Longfellow (1913) found that roaches, 

 prohahly Periplaneta orientalis , carried Staphylo co c cus 

 aureus on their legs. According to Herms (1939) this 

 coccus also has heen isolated from the antennae of the 

 croton hug ( Blattella germanica ) . 



Hindle and Duncan (1925") found Staphylococcus aureus 

 to die out quickly after ingestion hy the tick, Argas 

 persicus . Duncan (1926) supported these results hy the 

 observation that this coccus was greatly inhibited hy the 

 gut-contents of the tick. The same hactericidal effect 

 against this organism was found hy Duncan to he character- 

 istic of the gut-contents of Ornithodoros mouhata and 

 Stomoxys calcitrans hut not "by Cimex lectularius , Rhodnius 

 prolixus , Musca domes tica , Aedes cinereus , and Anopheles 

 hifurcatus . 



St. John, Simmons, and Reynolds (1930) found Staphy - 

 lococcus aureus to survive for at least 2k hours in the 

 gut of the mosquito, Aedes aegypti , though it could not 

 he demonstrated after an interval of seven or more days.
