BACILLUS OF RAUSCHBRAND. 299 



B. BACILLI PATHOGENIC IN ANIMALS. 



The following bacilli have been recognised as the 

 exciting agents of infective diseases, partly in the case 

 of domestic animals, and partly in animals used for 

 experiments : 



Bacillus of Rauschbrand. 

 (Bacterie du Charbon symptomatique.) 



In the case of Kauschbrand of cattle, Bellinger and 

 Feser, and later Arloing, Cornevin, and Thomas, have 

 found large rods, resembling anthrax bacilli, but never- 

 theless distinctly different, and have come to the con- 

 clusion that they are the exciting agents of the disease. 

 This disease, which chiefly attacks young cattle, a half Symptoms of 

 to four years old, and lambs, and which often runs R 

 through herds in the form of very fatal endemics, begins 

 with loss of appetite, followed chiefly by the formation 

 of an irregular swelling in the skin at some part 

 or other of the body; this swelling rapidly increases 

 in size, and distinct crepitation can be felt at its centre. 

 Death occurs 36 to 48 hours after the commencement 

 of the symptoms, the temperature rising at first and 

 th6n sinking to an abnormal degree. On making a Post-mortem 

 post-mortem examination we find, at the seat of the ai 

 swelling in the subcutaneous cellular tissue a collection 

 of gas, which chiefly consists of a mixture of cabornic 

 acid and methane ; the muscles and cellular tissue are 

 soaked with a large quantity of sero-sanguineous fluid, 

 and the surface of the muscles are of a black colour ; 

 the tymphatic glands in the neighbourhood of the part 

 affected are markedly hyperaemic. In the internal 

 organs there are no characteristic or constant alter- 

 ations. In the serous fluid between the fibrilla? of the 

 muscle, and in the subcutaneous cellular tissue there are 

 large numbers of bacilli ; these may also be found in 

 cover glass preparations made from the liver and spleen, 

 and in the blood vessels and capillaries, though this is 

 rare, and they are only found in these situations in
