110 SANITARY ENTOMOLOGY 



of animals dead from anthrax externally sterilized eggs of Musca 

 domestica, Calliphora vomitoria, Lucilia ccesar and Sarcophaga carnaria 

 and from day to day dissected the larva; feeding on this flesh, always 

 demonstrating anthrax germs in their bodies, and he further proved 

 that these larvae retained the germs in their bodies through pupation to 

 maturity and for at least nine days after maturity. He fed flies on 

 meat polluted with anthrax and demonstrated twenty-four hours later 

 the bacilli in the feces and on the eggs. Graham-Smith (1912) found 

 that many blow flies (Calliphora erythrocephala and Lucilia casar) 

 which emerged from larvae fed on meat infected with anthrax spores were 

 infected and remained so for 15 daj's or more. He also found that a large 

 proportion of house flies (Musca domestica) which develop from larvae 

 fed on spores of B. anthracis are infected. Because of the habit of blow 

 flies of breeding in and attacking wounds there have been many cases 

 of human anthrax on the battle front in Europe. The ease with which 

 this may occur is quite evident in view of the above quoted investigations. 



Bacillus cloadfE Jordan has been found in the alimentary canal of 

 Musca domestica in London by Nicoll (1911). 



Bacillus coli Escherich, an organism normalh' found in the alimentary 

 canal of man, but often found causing secondary infections, was found 

 by Cao (1906B) in various strains adhering to the eggs at the time of 

 oviposition of flies caught in the laboratory (Musca domestica, Sarco- 

 phaga carnaria, Lucilia cwsar, and Calliphora vomitoria). 



Bacillus coli amaerogenes was isolated by Scott (1917) from Musca 

 domestica caught in Washington. 



Bacillus coli commumior Dunham, an abundant inhabitant of the 

 human and animal intestine, has been isolated from the body and intes- 

 tinal contents of Musca domestica in New York and Washington by 

 Torrey (1912) and Scott (1917). 



Bacillus coli commwnis Escherich, an organism common in the intes- 

 tine of man and animals and associated with a large variety of lesions, 

 has been isolated from the body and intestinal contents of Musca 

 domestica by Torrey (1912), Nicoll (1911), Scott (1917) and Cox, 

 Lewis and Glynn (1912). 



Bacillus coli mutahilis was found on the body and in the intestines 

 of Musca domestica in London by Nicoll (1911). 



Bacillus "colisimile" Cao was fed by. Cao (1906B) to larvas of Musca 

 domestica, Calliphora vomitoria, Lucilia ccesar and Sarcophaga carnaria 

 in flesh and he later demonstrated its abundant presence in the feces of 

 the larvas. 



Bacillus cuniculicida Koch and GaffTky, the cause of SEPTICEMIA 

 in rabbits and guinea pigs, was isolated by Scott (1917) from house flies 

 (Musca domestica) caught in Washington, and he looks upon the fly
