OCCURRENCE AND PATHOLOGY OF NEPHROCALCINOSIS IN PIG.

Five hundred and eighty-six kidney samples were screened to establish the diversity of renal disorders in pigs irrespective of age, sex and breed at organised and unorganised farms of Bikaner, Jaipur and Alwar districts of Rajasthan. Out of 586 specimens, a total of 154 kidneys revealed macroscopic lesions. In five(3.25 per cent) cases of nephrocalcinosis without stone and 2(1.30 per cent) cases with stone, kidneys without stone and with stone on medullary and cortical region were processed for further histopathological examination at the Department of Veterinary Pathology, Bikaner. The gross lesion showed white streaks in colour on the medullar and cortical surface of kidney and nephrolithiasis. The surface appeared whitish in colour, shiny in appearance and hard in consistency. Histopathological examination revealed calcification of tubular epithelium and some glomeruli. Severe expansion of the interstitium by inflammatory cells, consisting predominantly of lymphocytes and fibrosis of tissue were also observed. [ABSTRACT FROM AUTHOR]
