such a case be diagnosed, the removal of the cause and the provision 

 of good quarters and wholesome food would probably be sufficient 

 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 predisposing 

 factors in this disease. Primarily, the disease is the result of in- 

 fection. Pyogenic bacteria may cause the condition, but more fre- 

 quently it is caused by a pleomorphic organism that has been named 

 corynebacillns renalis. 



Lesions. — The pelvis of the kidney is dilated with a thick, brown- 

 ish, purulent fluid and tissue shreds. The mucosa of the renal pelvis 

 is thick and contains hemorrhagic 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 sensitiveness 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. Con- 

 siderable 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. 



Urine has been collected from the bladder of the carcasses of 

 swine that have been slaughtered, and analyzed. It is possible that 

 there may be some modification of the urine of slaughtered animals, 

 but it is doubtful if the changes are of much significance. 



Albuminuria has been found to exist in swine showing a high 

 temperature, particularly cases that have been afEected with cholera. 

 The urine has also been found to contain varying quantities of al- 

 bumin in which there was an acute nephritis. Pneunionic cases also 

 evidenced albumin in the urine. 



The exact cause of albuminuria is still being debated. The con- 

 dition in swine, as well as in other animals, occurs in those cases
