FAMILY V. BRUCELLACEAE 



397 



bining form in such specific epithets as 

 aviseptica, boviseptica, suiseptica, etc. Names 

 of this type were apparently introduced 

 about 1896. 



The confusion that exists in regard to the 

 scientific name of this species should be 

 clarified by appropriate action taken by the 

 International Judicial Commission on Bac- 

 teriological Nomenclature. A strict applica- 

 tion of the Priority Rule in the Bacteriologi- 

 cal Code would apparently result in the 

 introduction of a specific epithet gallicidus 

 never used in the literature except by its 

 author. A careful review of the early litera- 

 ture might even reveal some other binomial 

 validly published before 1883. No attempt 

 is made here to list the various names that 

 have been used for this species as found in 

 various animals such as man, children, 

 calves, buffaloes, goats, sheep, swine, 

 horses, cats, dogs, ferrets, rats, mice, rab- 

 bits, guinea pigs, fowls, ducks, swans, wild 

 pigeons, pheasants, canaries, etc. 



Source: Early isolations were from fowls, 

 cattle and rabbits. 



Habitat: The cause of chicken cholera 

 and hemorrhagic septicemia in warm- 

 blooded animals.
