108 SWINE DISEASES 



with extensive kidney lesions are usually in fair condition 

 when they are observed at the time of slaughter. 



Treatment. The application of therapeutic agents 

 for the relief of chronic interstitial nephritis in swine has 

 not been practiced. Should such a case be diagnosed, 

 the removal of the cause and the provision of good 

 quarters and wholesome food would probably be suf- 

 ficient until the animal was in condition for slaughter. 



Pyelonephritis 



Pyelonephritis is an inflammation of the pelvis of the 

 kidney, a condition that has been observed in swine but 

 is rare. 



Etiology. Calculi and parasites are frequently pre- 

 disposing factors in this disease. Primarily, the disease 

 is the result of infection. Pyogenic bacteria may cause 

 the condition, but more frequently it is caused by a 

 pleomorphic organism that has been named corynebacillus 

 renalis. 



Lesions. The pelvis of the kidney is dilated with a 

 thick, brownish, purulent fluid and tissue shreds. The 

 mucosa of the renal pelvis is thick and contains hemor- 

 rhagic spots. The kidney may contain purulent centers 

 or it may be converted into a purulent mass. 



Symptoms. Frequent urination is a symptom of 

 this disease, the urine voided being cloudy. Loin sensi- 

 tiveness and inappetence are also observed in these 

 cases. 



Treatment. Thus far no treatment has been found 

 that is of any value. 



Albuminuria 



Albuminuria is a condition in which there is elimination 

 of albumin in the urine. 



Urinalysis is now in its infancy in veterinary medicine. 

 Considerable time and energy have been devoted to the 

 study of urine from some animals, particularly the horse, 

 but little attention has been given to systematic urinalysis 

 of swine.
