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 Bacteriological Nomenclature. A strict application of the Priority Rule in the Bacteriological 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 literature 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, rabbits, 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.

2. Pasteurella septicaemiae (Bergey et al., 1925) Breed, comb. nov. (Bacillus septicaemiae anserum exsudativae Riemer, Cent. f. Bakt., I Abt., Orig., 37, 1904, 648; Eberthella septicaemiae Bergey et al., Manual, 2nd ed., 1925, 250.)
