DESCRIPTION OF SH 





In a nourishing fluid they are 

 overcome by the presence of micro- 

 cocci, Bacterium termo or Bacillus 

 subtilis. 



They occur in the soil, in putrid 

 blood, and many putrid albuminous 

 fluids, and occasionally in the blood- 

 vessels of man and animals after 

 death. 



Bacillus septicus acuminatus 

 (Babes). Rocfe with lancet-shaped 

 ends, about the size of the bacilli 

 of mouse-septicremia. They exhibit 

 polar staining. They can be culti- 

 vated at 37C. 



On agar and blood serum the 

 colonies are circular, transparent, 

 and later coalesce and form a yel- 

 lowish layer. 



They are fatal to rabbits and 

 guinea-pigs in from two to six 

 days. 



They were isolated from an infant 

 after death from septic infection 

 occurring five days after birth. 



Bacillus septicus agrigenus 

 (Nicolaier). Rods resembling Ba- 

 cillus septicaemias haemorrhagicae. 



Colonies circular, granular, with 

 concentric zones of varying tints of 

 brown. 



Intravenous injections are fatal 

 to rabbits in twenty-four to thirty- 

 six hours, and bacilli abound in the 

 blood. 



They occur in recently manured 

 soil. 



Bacillus . septicus keratoma- 

 lacise (Babes). Short thick rods 

 singly, and in pairs : often capsu- 

 lated. 



Colonies white, with dentated 

 contours. 



The bacilli, inoculated in the depth 

 of gelatine, grow in the track of 

 the needle and on the surface ; gas 

 bubbles are developed. 



On agar the growth is arbores- 

 cent and opalescent. 



On blood serum they form a 

 shining, somewhat transparent, 

 dentated film. Cultures have an 

 ammoniacal odour. 



They produce purulent inflam- 

 mation of the cornea. 



They were isolated from the 

 cornea in a case of septicaemia 



following 

 child. 



keratomalacia 



Bacillus septicus ulceris jran- 

 graenosi(Babrs).- -short ro.U 

 ; /x in width. 



Inoculated in the depth of gela- 

 tine they produce li a and 

 gas in the track of the needle. 



On agar greyish-white shining 

 patches are found. 



On potato they develop a trans- 

 parent film. 



They are pyogenic in rabbit - 

 mice. 



They were isolated from the 

 internal organs and blood in a case 

 of septicaemia following gangrene. 



Bacillus septicus vesicae 

 (Clado). Rods 1-6 to 2 p in length, 

 5 /n in width. 



Colonies circular, transparent, 

 yellowish. 



The bacilli inoculated in tin- 

 depth of gelatine form a delicate 

 filament composed of closely-packed 

 colonies, and on the surface th- 

 a filmy growth. 



On agar they form a gri-\ 

 white layer, and on j>tato the 

 growth is dry and brown. 



They are poisonous to rabbi te, 

 guinea-pigs, and mice. 



They were isolated from urine 

 from a case of cy- 



Bacillus sessilis (I- K 

 Rods resembling those of thi 

 bacillus. 



They are said to be distinguished 

 by fission commencing in a newly 

 formed rod before it has been set 

 free from the spore. 



They were isolated from the blood 

 of a cow. 



Bacillus smaragdino-phospho- 

 rescens(Kat/). Rods with pointed 

 c-mN. 'I p in length, 1 j* in width. 



Coloni.- i.iintly yellow, 



with concentric rings. 



Inoculated in the gela- 



tine a white filament forms in the 

 track of tin- m-edle and a greyiah- 

 white patch on the free surface ; 

 and there is son 



In bn.th they produce turbs : 



On potato they produce a thin 

 brownish-yi'llow film. 



They are photogenic, and the
