URINARY APPARATUS. 175 



ored; secretion of milk suspended, great depression and general 

 weakness of the body. Dark red areas on mucous membranes 

 which (spots) become coated with grayish white layers, when the 

 latter drop off and leave ulcerous erosions. Most animals die on 

 the fifth or sixth day. 



Calf diphtheria. Diphtheria vitulorum is an acute infectious 

 disease characterized by compous-diptheritic accumulations on the 

 buccal mucous membrane and caused by the Bacillus necrophorus. 



Stomatitis pustolosa contagiosa is an exanthema with a typical 

 course. It occurs in the form of pustules, principally at the mouth, 

 and is characterized by its mild course. Period of incubation 3-5 

 days. At first appearance of eruption there is fever, but this soon 

 subsides. Horses refuse feed, they salivate, mouth painful to the 

 touch. Within 2-3 days minute nodules or blisters appear on the 

 mucous membrane; these are at first red, then gray or yellow, 

 break open and form ulcers. Intermaxillary glands swollen, con- 

 junctivitis, now and then ulcers on the outer part (skin) of the 

 lips, forearm and body; healing requires 10 days to two weeks. 



Hog cholera, an infectious septicemia produced by a filterable, 

 ultramicroscopic virus, readily transmissible. In its course multiple 

 hemorrhages appear in the mucous membranes and skin. In the latter, 

 superficial necrosis. At first a general febrile affection without local- 

 izations, aggravation of symptoms, conjunctivitis, red patches on the 

 skin, often vesicular eczema and diphtherioid lesions on the buccal 

 mucus membrane, especially that of the tongue. In the beginning 

 constipation and bloating of the abdomen followed by excessive diar- 

 rhoea, stinking feces, drawing up and painfulness of abdomen. Sep- 

 ticemic, peracute cases also observed. 



Swine typhus, typhus suis, a typical enteritis, not readily 

 transmitted, caused by Bacillus suipestifer. Febrile chronic affec- 

 tion with progressive emaciation. Often accompanying Hog 

 cholera and difficult to differentiate. 



Dog plague (Stuttgart), typhus canum, a severe, acute, typical 

 contagious infectious disease, confined almost exclusively to the di- 

 gestive tract. Occurs in the form of a severe gastroenteritis and 

 ulcerous stomatitis. Vomiting, anorexia, exhaustion, laziness, coma- 

 tose condition. Never any elevation of temperature, often hypo- 

 thermia. 



Diarrhe? of calves. Dysenteria neonatorum. A neracute in- 

 fectious disease of new-born calves, resembling a septicemia. Char- 

 acterized by severe diarrhea, whitish stinking feces, general weak- 

 ness, and usually terminating in death within a few days. 



Red Dysentery. Dysenteria coccidiosa bovum, a hemorrhage 

 enteritis caused by coccidia. 



g. Intoxications. 



Lupinosis is an intoxication disease affecting the body as a 

 whole. It is caused by a poisonous principle (lupinotoxin) which 

 occurs in lupines. Diminished appetite, increased temperature, icteric 

 coloration of conjunctiva, general weakness, cerebral depression. 

 Urine yellow, contains bile pigments and albumin.
