Tribe 7. Hemophilaeae, Nov. Trib. 



Minute parasitic forms growing only in presence of hemoglo- 

 bin, ascitic fluid or other body fluids. 



Genus 9. Hemophilus Committee 1917c, p. 561 



Synonyms: Pyobacillus? Koppanyi 1907; Diplobacillus Morex 1896, 

 not Diplobacillus Weichselbaum 1887. 



Minute rod-shaped cells, sometimes thread forming and pleo- 

 morphic, nonmotile, without spores, strict parasites, growing 

 best (or only) in the presence of hemoglobin, and in general re- 

 quiring blood serum or ascitic fluid. Gram negative.

 occur in long threads and form rhizoid colonies. Form of rod usu- 

 ally not greatly changed at sporulation. 



The type species is Bacillus subtilis Cohn.
