6. Septicemic Affections of New Born Animals. The acute 

 septicemic affections of the newborn may clinically be collected, 

 into two groups. In the first group all those affections are 

 considered in which manifestations of an acute gastro-intestinai 

 catarrh are present, and its most conspicuous symptom is 

 diarrhea, while the affections of the second group are charac- 

 terized by suppurative inflammatory processes in various 

 organs and about the body, especially in the joints and extremi- 

 ties. In spite of the variance of the sjTiiptoms the more recent 

 investigations indicate with great probability that the same 

 bacteria produce the diseases belonging to both these groups. 

 It is also probable that several species are concerned in the 

 etiology of the diseases and that the differences in the course 

 of the disease depend especially on the mode of infection. 



While the two forms of disease are apparently very closely 

 related, or possibly even identical in their etiological relation, 

 we consider that the question has not been completely solved, 

 especially as in some of the enzootics frequently only one or 

 the other form comes under observation. Accordingly from a 

 practical standpoint it is deemed advisable in discussing the 

 diseases to separate the forms from each other. 



(a) White Scours of Sucklings: Dysenteria neonatorum 



{Diarrhea neonatorum, Diarrhee des nouveawics [French]; 

 Ruhr der Sduglinge [German'].) 



White scours of newly born is an acute, contagious, infec- 

 tious disease affecting the animals in the first days of their 

 lives, and is observed usually as a stable affection characterized 

 by profuse diarrhea and by rapid exhaustion. 



History. The cause of this dangerous and fatal disease has been 

 thought until recently to be either due to dietetic errors, especially 

 as a result of feeding milk of improper constitution (Tolnay 1799), 

 and also caused by improper feeding of the mother animal, or else as 

 a result of climatic conditions. Based on this supposition the affection 

 has been associated with the gastro-intestinai catarrh of adults which 

 results from similar causes. However, Obich (1865) and Roloff (1875) 

 proved that the disease is transmissible from stable to stable, and 

 further investigations proved beyond a doubt the infectious nature 

 of the disease. Frank (1876) concurred in these tindings, and at 

 the present time this view is generally accepted. The recent investiga- 

 tions of Poels (1899) and Joest (1902), and especially those of Jensen 

 (1893 and 1905) have cleared the etiology of white scours in most 

 points.
