Renal Nosematosis in Young Rubbits

Abstract
The kidneys of 100 of 2,338 rabbits (4.3%) slaughtered for human consumption had focal cortical depressions. Histologically, the lesions in these kidneys consisted of focal granulomatous nephritis to chronic interstitial nephritis with scarring. Nosema cuniculi was demonstrated microscopically in 35 (35%) of the grossly affected kidneys. The number of organisms decreased as the lesions became older.
