2O6 BACTERIOLOGY. 



growth in the needle track in test-tubes (Plate 

 XXVI., Fig. i), and characteristic, thread-like, 

 branching, or star-like colonies form in plate- 

 cultivations (Plate XXVI., Fig. 2). Inoculated 

 into mice and rabbits, a fatal result is pro- 

 duced ; but experiments with pigs were unsuc- 

 cessful. Pigeons were also susceptible, and the 

 bacilli were detected in their blood (Plate XXVI., 



Fig- 3). 



Bacillus of choleraic diarrhoea from meat- 

 poisoning, Klein. * Rods from 3 9 /x, in length, 

 1*3 p. wide, rounded at their extremities, singly 

 or in chains of two. Spore formation occurs, the 

 spores being i //, thick, oval, and situated in the 

 centre or at the end of the rod. 



Feeding with the bacilli and inoculation produced 

 positive results. At the autopsy, pneumonia, peri- 

 tonitis, pleuritis, enlargement of the liver and spleen, 

 and haemorrhage were observed, and bacilli were 

 present in the blood and exudations of the animal. 

 They occurred in several fatal cases of choleraic 

 diarrhoea at Nottingham and Welbeck. Symp- 

 toms affected many people who had partaken of 

 beef and ham sandwiches, and baked pork, which 

 produced languor, giddiness, griping in the abdo- 

 men, diarrhoea, nausea, vomiting, and in some 

 cases death. Bacilli were found in the blood 

 and juices, and especially in the capillaries of 

 glomeruli of the kidney.
