DESCRIPTION Ol sri.i II .-. 



the bacilli, inoculated into the con- 

 junctiva of healthy rabbits, produces 

 severe ophthalmia. The poisonous 

 principle is a chemical ferment 

 ulir'm. Boiling, which does not 

 destroy the spores of the bacillus, 

 destroys the ferment, and cultiva- 

 tions started from these spores, 

 though teeming with jequirity 

 bacilli, are quite harmless (Klein). 



The bacilli occur in infusions 

 of the beans of Abrus precatorius 

 or jequirity. 



Bacillus of Schaffer (Freuden- 

 reich). Rods 2 to 3 p. in length, 

 1 f in width, and long filaments. 



Colonies circular, granular, yel- 

 lowish. 



In the depth of gelatine a growth 

 develops in the track of the needle 

 and a greyish layer on the surface. 

 On agar the growth is greyish 

 and sometimes brownish, and on 

 potato yellowish. 



In broth with peptone and milk 

 sugar there is copious formation of 

 gas-bubbles. 



They closely resemble Bacillus 

 coli communis. 



They were isolated from cheese 

 and potato. 



Bacillus of Scheurlen. Rods 

 1-5 to 2-5 p in length, -5 fi in width. 

 They were isolated from cancerous 

 growths by Scheurlen, and were 

 later identified with Bacillus epider- 

 midis. 



Bacillus of Schou. Short rods 

 and cocci-forms. 



Colonies are spherical, opaque, 

 and granular. 



The bacilli inoculated in gelatine 

 rapidly liquefy it, and a white de- 

 posit forms at the bottom of the 

 liquid. 



Rabbits inoculated in the trachea, 

 or made to inhale pure-cultures, are 

 said to develop fatal pneumonia. 

 They were isolated from rabbits 

 with pneumonia, following section 

 of the vagi. 



Bacillus of swine plague 

 (p. 3ol). 



Bacillus of Tommasoli 

 rods from 1 to 1*8 \i in length, ami 

 25 to :'> p. in width, singly, and in 

 short chains. 



Colonies grey and shiny. 



In the depth of gelatine ti 

 form a filament composed 

 packed colonies. an<l on the surface 

 a shining mass. 



On agar the growth con-i-i 

 greyish patches. 



On potato the growth is granular 

 and yellowish-white. 



Cultures rubbed into the skin 

 are said to produce a vesicular 

 eruption. 



They were isolated from the 

 scalp in a case of sycosis. 



Bacillus of Utpadel. K.uS I-.':* 

 to 1'5 n in length, and '75 to 1 p, 

 in width, singly, in pairs ;unl short 

 chains. 



Colonies milk-white. 



On the surface of gelatine the 

 growth is milk-white, and on agar 

 yellowish-white. 



Injected subcutaneously in cats, 

 guinea-pigs and mice, they produce 

 extensive oedema, and a fatal ter- 

 mination. 



They were isolated from the 

 human intestine. 



Bacillus of Winogradsky. (See 

 Bacillus nitrificans.) 



Bacillus ovatus minutissi- 

 mus (Unna). Short rods with 

 pointed ends '6 to /i in length, 

 4 /x in width, singly, and in 

 masses. 



Colonies are minute, granular an-1 

 yellowish. 



The bacilli inoculated in 

 depth of gelatine form a filament 

 of closely packed gre\ 

 colonies, and on the free surface 

 there is a shiny, greyish 

 layer. 



On agar the growth JH very sum 

 lar, and on potato a! 



They were isolated from tin- akin 

 in eczema seborrlm < 



Bacillus oxytocus perniciosus 

 I Wys-nkowitch). KnU short and 

 thick. 



Ionics circular, granular, yel- 

 lowish. ..r y. ll-.u 



The bacilli inoculated in i 

 depth of g.-latuir produce a gi 

 resembling Friedliwkr'i pneumo 

 coccn> 



'1 1), v coagulate milk.
