Abstract

STOEV, S. D., 1999. Historical data, spreading, aetiology and epidemiology of mycotoxic nephropathy (ochratoxicosis) in pigs. Bulg. J. Agric. Sci., 5: 515-524

Reference was made concerning the frequency and occurrence of mycotoxic porcine nephropathy in various countries. The aetiology of the disease was refered. The main ochratoxin-producing fungi and the necessary condition for ochratoxinogenesis were also refered. The review was made in order to clarify the most commonly encountered nephrotoxic contaminants in various feeds and foods of animal origin, their contamination levels and their importance in development of mycotoxic nephropathy. The reference was made concerning the chemical structure and physicochemical properties of various ochratoxin-metabolites as well their stability in the storage conditions. The feeds and foods optimized growing of ochratoxinogenic fungi as well most suitable storage conditions were also refered.

Key words: ochratoxin A (OTA), ochratoxicosis, mycotoxic porcine nephropathy (MPN)
