b. paratyphosus Schottmiiller B., b. Aertryck, b. Gaertner,. 

 L.I.P.M., b. Gaertner orig. A. He says that on glucose, 

 levulose, mannit, dulcit, maltose, dextrin, galactose, 

 arabinose, and sorbit, acid and gas are produced, while no 

 action occurs on lactose, cane-sugar, inulin, amygdalinr 

 salicin, raffinose or erythrit. He states that the indoi 

 reactiou is variable, but more often found in b. paratyphoid 

 and b. aertryck than in b. Gaertner, and says that on two 

 occasions b. paratyphosus Schottmiiller A, and also the 

 Brion and Kayser strain, showed strong alkalinity on milk 

 after two months. He gives notes of two atypical para- 

 typhoid organisms which gave strong acidity on milk, acid 

 and gas on salicin, otherwise resembling the Gaertner 

 type organisms. 



MacConkey (1906) (7) describing the organism associated 

 with an outbreak of food poisoning at Fulham, isolated from 

 the spleen of a child and the hind limb of a rabbit, says 

 that it corresponded in every way with those of b. enteri- 

 tidis (Gaertner) group, and notes that acid and gas were 

 produced on glucose, mannose, maltose, arabinose, raffinose, 

 mannit, dulcit, sorbit and dextrin. (He notes reasons for 

 the unreliability of the raffinose test). No action took 

 place on lactose, cane-sugar, adonit, erythrit, inulin. 



MacConkey states that b. L. Hume ferments adonit with 

 the production of acid and gas. (A similar organism is 

 later noted by the author). 



Savage and Gunsen (1908) (8) describing an outbreak of 

 food poisoning due to infected brawn, discovered a bacillus 

 which they finally agreed to place in the Aertryck branch 

 of the Gaertner group. It produced acid and gas on glucose, 

 mannit, dulcit, and maltose, but showed no action on lac- 

 tose, saccharose or salicin. Litmus milk was turned acid 

 and later alkaline.
