166 Pyo-Septiceinia of Sucklings. 



with the secretion small tissue shreds or cartilaginous and bone 

 particles may be discharged. The motility of the affected joints 

 is interfered with by the pain and by the tense and swollen 

 condition. The animal does not support the body with the 

 affected extremity, and protects it from touching the floor. If 

 several joints are affected at the same time, the animal no 

 longer moves around, but lies constantly on the ground. 



The affection of the lungs is indicated by a painful cough 

 and rapidly increasing difficulty in respiration, which is later 

 associated with a profuse nasal discharge, as an indication of 

 a developed purulent bronchitis. Percussion reveals only in 

 circumscribed areas a dull or tympanitic sound ; by auscultation, 

 however, the most varied catarrhal sounds, such as whistling, 

 roaring, moist rales, and in parts also bronchial breathing, may 

 be distinguished. Sometimes friction sounds may also be heard 

 over some parts of the lungs and the heart, indicating an acute 

 exudative inflammation of the corresponding serous mem1)ranes. 

 In such cases the patients lie much on the chest with extremi- 

 ties drawn under the body, or with legs extended. 



In the presence of an inflammation of the brain and its 

 membranes, the patients are much depressed and apathetic. 

 Sometimes chronic spasms may be noticed in some of the mus- 

 cles or groups of muscles, or the animal may struggle consid- 

 erably. With relative frequency, symptoms of meningitis may 

 be present as the result of the extension of the inflammation 

 to the medulla ; still later paralysis may appear in the extremi- 

 ties, or in the territory of some of the facial nerves. 



Symptoms showing disturbances of the digestive organs 

 are hardly ever absent, and in some cases they may even be 

 present at the onset of the disease. Severe colicky s^^njitoms 

 may appear when the animals lie in a cramped condition on 

 the ground with the head turned toward the abdomen ; touching 

 of the abdomen causes considerable pain. The constipation 

 which is at first present is followed by diarrhea, the animals 

 passing first light, later dark colored, and very fetid, fluid feces. 

 The feces soil the parts around the anus, and later the excre- 

 ments and urine are passed involuntarily. 



In the meantime the animals become greatly emaciated, 

 they lose their strength, the eyes are sunken deep into the 

 orbits, the action of the heart becomes accelerated and weak, 

 the body temperature drops below normal, the extremities, the 

 face and the ears become cold, the body is covered with per- 

 spiration, and finally the patients die, with symptoms of con- 

 vulsions or without any struggle. Death may occur before the 

 progress of the disease through the stages described, from 

 asphyxiation or paralysis of the brain. 



In cases of pure septicemia only high fever and severe 

 diarrhea, sometimes also hematuria are observed ; in such cases 

 the patients die within a few days as they rapidly lose strength.
