چکیده
Nephrocalcinosis is a chronic disorder which may be resulted in decrease in growth rate and finally mortality in severe condition. Nephrocalcinosis is defined as the presence of calcification in the kidney. A total number of 80 ornamental fishes of different species included of discus fish (Symphysodon discus), angelfish (Pterohyllum sp.), goldfish (Carassius auratus) and oscar fish (Astronotus ocellatus) were randomly collected from some aquarium shops. The clinical examination indicated the presence of excessive mucous secretion, detachment of the scales, exophthalmia. Also skin petechiae and haemoharrgia particularly at the base of the fins was observed. Histopathological examination revealed presence of basophilic deposits in tubular sections of kidney, distinct dilation of tubules and fibrosis around glomerulus with chronic glomerulitis and multiple microscopic calculi in tubules with different size can be pathognomonic for this disease and it is the best indicator for diagnosis of this disease.
