304 A MANUAL OF BACTERIOLOGY 



which may assume a typhoid type, and two cases of tetragenus 

 cerebro -spinal meningitis are recorded by Ramond and Resibois. 1 



Sarcina ventriculi 



An organism occurring in the contents of the stomach, especially 

 in cases of dilated stomach. Originally described by Goodsir in 

 1842. 



It occurs as a large ovoid cell, several of which are grouped to- 

 gether quadrilaterally so as to form more or less cubical masses, 

 the so-called " woolpacks." According to Falkenheim, it forms 

 on gelatin in thirty-six to forty-eight hours roundish, prominent 

 colonies of a yellowish colour, and in neutral hay infusion a 

 brownish film and flocculi. It produces an acid reaction. 



Other sarcinse also occur in the stomach. 



Clinical examination. 1. The organism can be detected in the 

 vomit, etc., most readily by examination in the fresh state, a 

 little of the material being placed on a slide, diluted with water 

 if necessary, irrigated or not with iodine solution, covered with a 

 cover-glass, and examined. 



2. Film preparations may be stained with weak carbol fuchsin, 

 or by Gram's method. 



Other Organisms met with in Suppurative and 

 Septic Conditions 



Many other organisms may be met with in various suppurative 

 and septic processes, e.g. : 



a. The B. coli in cystitis and pyelitis, ischio -rectal abscess, 

 peritonitis associated with perforation and intestinal obstruction, 

 and puerperal fever (see Chapter X). 



b. The Diplococcus pneumonice in abscesses, empyema, arthritis, 

 meningitis, pericarditis, peritonitis, etc. (see Chapter XII). 



c. The B. typhosus in abscesses, cholecystitis, empyema, and 

 osteomyelitis (see Chapter X). 



d. Anaerobic bacilli, such as B. cedematis and B. perfringens, 

 in foul, gangrenous wounds (see Chapter XIII).
