94 HEMORRHAGIC SEPTICEMIA 



HEMORRHAGIC SEPTICEMIA IN CATTLE. 



Synonyms. Wild und Rinderseuche; Pasteurellosis bovum; 

 SSphcSmie hemorrhagique du boeuf. 



% 77. Characterization. Hemorrhagic septicemia in 

 cattle is determined by an acute attack usually running a 

 rapid course and terminating fatally. The lesions consist 

 largely of hemorrhagic areas more or less widely distributed 

 throughout the body and due to the presence ot a specific 

 microorganism. 



§ 78. History. In 1878, Bollinger described under the 

 name of Wild und Rinderseuche an epizootic disease which 

 killed a large number of wild boars and deer in the Royal 

 game preserves of Munich. After the disease in these animals 

 had died out, the domestic cattle in the neighborhood began 

 to die of the same or a very similar affection. He reports it to 

 be sudden in its onset and rapidly fatal in its course, with a 

 mortality of 90 per cent. Death occurred in from 12 hours to 

 a few days after the appearance of symptoms. 



An exanthematous and a pectoral form are described. In 

 the exanthematous form there are large and small hemorrhages 

 disseminated throughout the muscles and viscera. The intes- 

 tines exhibit large numbers of ecchymotic areas, while the 

 submucous tissue is infiltrated with a serous exudate. L,arge 

 hemorrhagic tumors infiltrated with serum are abundant in 

 the subcutaneous tissue, often extending into the muscles. The 

 mucous membranes of the tongue, larynx and pharynx, and the 

 lymphatic glands of these regions, are swollen and infiltrated 

 with more or less bloody serum. In the pectoral form, there is 

 a hemorrhagic lobular pneumonia, with considerable infiltra- 

 tion into the interlobular tissue of a serofibrinous exudate. 

 The pleura is infiltrated and inflamed and covered with a 

 fibrinous exudate. The pleural cavities contain from two to 

 twenty-five litres of liquid. At the same time there exist a 

 certain degree of hemorrhagic enteritis and the widely dissem- 

 inated hemorrhagic lesions common to the preceding form.
