FAMILY ENTEROBACTERIACEAE 



503 



Agr. Exp. Sta. Bull. 400, 1940, 43-70, 

 for a discussion of this species. 



Rods: 0.5 by 1.0 to 1.5 microns, occur- 

 ring singly. Motile with peritrichous 

 flagella. Gram-negative. 



Gelatin colonies: Small, circular, gray- 

 ish, granular, becoming yellowish-brown. 



Gelatin stab: Flat surface growth. 

 No liquefaction. 



Agar colonies: Small, circular, grayish, 

 entire to undulate. 



Agar slant: Filiform, grayish, moist, 

 entire growth. 



Broth: Turbid. 



Litmus milk: Slightly acid, becoming 

 alkaline. 



Potato: Grayish -white streak. 



Indole not formed. 



Nitrites produced from nitrates. 



Acid and gas from glucose, fructose, 

 galactose, arabinose, maltose, dextrin, 

 mannitol, sorbitol and inositol. Acid 

 from glycerol. No action on lactose, 

 sucrose, raffinose, inulin, salicin or 

 adonitol. 



Reduces trimethylamine oxide (Wood 

 and Baird, loc. cit.). 



Hydrogen sulfide produced. 



Optimum temperature 37 °C. 



Aerobic, facultative. 



Antigenic structure: [I], IV, [V],XII: 

 i: 1, 2, 3... 



Source: Isolated during a mouse ty- 

 phoid epidemic in the Hygienic Institute 

 of Greifswald, German}-. 



Habitat: Causes food-poisoning in 

 man. A natural pathogen for all warm- 

 blooded animals. This type occurs more 

 frequently than any other type not con- 

 fuied to a specific host. Also found in 

 snakes bj' Hinshaw^ and McNeil (Amer. 

 Jour. Vet. Res., 6, 1945, 264). 



4a. iSalmonella typhiinuriuni (Type 

 Binns). (Bacillus paratyphcsus B Binns 

 type, Schtitze, Lancet, 1, 1920, 93; Group 

 VI of Hecht-Johansen, Copenhagen, 

 1923; Typus-Binns, Kauffmann, Zbl. f . d. 

 ges. Hyg., ^0, 1931, 273; Salmonella iij- 

 phimuriian var. Copenhagen, Kauffmann, 



Ztschr. f. Hyg., 116, 1934, 368; Salmon- 

 ella typhi-murium var. Binns, Schtitze 

 et al.. Jour. Hyg., 34, 1934, 339; Sal- 

 monella aerirycke var. Storrs, Edwards, 

 Jour. Bact., 30, 1935,471.) 



Morphology and cultural characters 

 indistinguishable from those of Sal- 

 monella typhimurium, except some 

 strains ferment maltose late or arc 

 anaerogenic. 



Antigenic structure: [I], IV, XII: i: 

 1, 2, 3 . . . (Edwards, Jour. Hyg., 36, 

 1936, 348). Many colonies may be ex- 

 amined before the specific phase flagellar 

 antigen is demonstrated. Differs from 

 Salmonella typhimurium in lacking anti- 

 gen V. 



Source : Isolated by Dr. McNee from a 

 case of food poisoning in man, France, 

 1919. 



Habitat: Natural host the pigeon, and 

 may infect other animals, including man. 



5. Sahnonella sp. (Type Koln). {Sal- 

 monella koln Sievers, Cent. f. Bakt., I 

 Abt., Orig., 150, 1943, 52; Salmonella 

 coeln Kauffmann, Acta Path, et Micro- 

 biol. Scand., Suppl. 54, 1944, 33.) 



Antigenic structure: IV, V, XII: y: 

 1,2, 3 . . . 



Source: A single culture isolated from 

 a human case of enteritis. 



Habitat: Not reported from other 

 sources as yet.

 (Bacillus paratyphcsus B, Stanlej^ type,

 food poisoning in Stanley', England by
