BACILLI 485 



BACILLUS MULTIPEDICULOSUS 



Authority. Fliigge, Die Mikroorganismen, 1886, p. 323. 



Where Found. In air and water. 



Microscopic Appearance. Long slender bacillus. It is not motile. 



Cultures. 



GELATINE PLATES. The depth colonies are round or oval, and smooth - 

 rimmed ; at some spots on the periphery broad, radial and concentric extensions 

 project, which consist of circular zoogkea masses. In from two to three 

 days these extensions are visible to the naked eye, but as they only occur here 

 and there, and only incline to any length at one end of the colony, the general 

 appearance is that of an insect with innumerable feet and antennae. No 

 liquefaction takes place. 



GELATINE TUBES. Forms short isolated extensions along the needle's path in 

 the depth. 



POTATOES. Dirty yellow, somewhat restricted, smooth expansions. 



BACILLUS STOLONATUS 



Authority. Adametz-Wichmann, Die Bakterien dcr Nutz- und Trink- 

 wasser, Adametz. Vienna, 1888. 



Where Found. In water. 



Microscopic Appearance. Bacilli two and a half times as long as broad. 

 Very motile. 



Cultures. 



GELATINE PLATES. Forms in the depth small whitish or yellowish brown 

 colonies, round or egg-shaped, with smooth rims. On the surface, protruding 

 ball-shaped colonies. In peptone-gelatine, without broth, they are brown in 

 colour. No liquefaction takes place. 



GELATINE TUBES. .Forms a whitish expansion at the point of inoculation, 

 whilst in the depth a slow granular growth makes its appearance. In older 

 cultures (about two to three weeks) the upper part of the needle's path becomes 

 widened in the shape of a bottle or funnel, and the sides covered with white 

 growths. No liquefaction takes place. ' 



AGAE-AGAB PLATES. From the centre of the colony variously twisted 

 branches extend, from which again numerous fine irregular ramifications 

 proceed. Under a low power it appears as a very thin, finely granular, 

 yellowish expansion, the branches of which appear like clubs. 



POTATOES. Forms a dirty white expansion.
