| Acute interstitial nephritis in dogs is caused most often by
Leptospira
interrogans
(
Leptospirosis in Dogs). Cats can develop leptospirosis, although signs are less severe than in dogs. Other infectious causes of interstitial nephritis in dogs include
Leishmania
donovani
and
Borrelia
burgdorferi
. Glomerulonephritis is the predominant renal pathology, so these diseases are considered immune complex diseases rather than true infections. Infectious diseases that cause vasculitis in dogs or cats (eg, feline infectious peritonitis, Rocky Mountain spotted fever, ehrlichiosis) may also cause renal failure. |
