ORDER IV. EUBACTERIALES 



muelleri of Schottmuller; named for Prof. 

 H. Schottmiiller, who isolated this organism 

 in 1899. 



Rods, 0.6 to 0.7 by 2.0 to 3.0 microns, 

 occurring singly and in pairs. Usually motile 

 by means of peritrichous flagella. Gram- 

 negative. 



Gelatin stab: No liquefaction. 



Agar colonies: Small, circular, bluish 

 gray, transparent, homogeneous, entire to 

 undulate. 



Broth: Turbid; thin, gray pellicle and 

 sediment. Fecal odor. 



Litmus milk: Slightly acid, becoming 

 alkaline. 



Potato: Grayish white, viscous growth. 



Indole not produced. 



Hydrogen sulfide is produced. 



Acid and gas from glucose, mannitol, 

 maltose, sorbitol, arabinose, xylose and 

 trehalose. Mucate and 1-tartrate are at- 

 tacked. Fermentation of dulcitol, inositol, 

 rhamnose and dl-tartrate is variable. No 

 action on lactose, sucrose, salicin, adonitol 

 or d-tartrate. 



Sodium citrate may or may not be uti- 

 lized. 



Nitrites produced from nitrates. 



Trimethylamine produced fromtrimethyl- 

 amine oxide (Wood and Baird, Jour. Fish. 

 Res. Board Canada, 6, 1943, 198). 



Aerobic, facultatively anaerobic. 



Optimum temperature, 37° C. 



Antigenic structure: 1, 4, 5, 12: b: 1, 2. 



Source: Isolated from cases of enteric 

 fever in man. Not a natural pathogen of 

 other animals. 



Habitat: A natural pathogen of man 

 causing enteric fever. Also found rarely 

 in cattle, sheep, swine, lower primates and 

 chickens.

 pertaining to abortion; L. adj. equinus per- 

 taining to horses; M.L. adj. abortivoequinus 

 pertaining to aborting horses. 



Rods, 0.2 to 0.5 by 1.5 microns, occurring 

 singly, occasionally in pairs. Motile by 

 means of peritrichous flagella. Gram-nega- 

 tive. 



Gelatin: No liquefaction. 



Indole not produced. 



Hydrogen sulfide not produced. 



Acid and gas from glucose, mannitol, 

 maltose, sorbitol, xylose, arabinose and 

 rhamnose. 1-Tartrate and dl-tartrate are 

 attacked. Fermentation of dulcitol and 

 trehalose is variable. 1-Tartrate may or may 

 not show late fermentation. No action on 

 lactose, sucrose, salicin, adonitol, inositol 

 or mucate. 



Sodium citrate is utilized. 



Nitrites produced from nitrates. 



Trimethylamine produced from trimethyl- 

 amine oxide (Wood and Baird, Jour. Fish. 

 Res. Board Canada, 6, 1943, 198). 



Antigenic structure: 4, 12: — , e, n, x. 



Isolated from the afterbirth of mares that 

 had aborted. 



Habitat: A natural pathogen of mares, 

 causing abortion; also infectious for guinea 

 pigs, rabbits, goats and cows, producing 

 abortion.

 1931) Schiitze et al., 1934. {Bacillus para- 

 typhi abortus ovis Schermer and Ehrlich,
