Effect of aflatoxin, ochratoxin and sterigmatocystin on microorganisms from sheep rumen: Effect of aflatoxin, ochratoxin and sterigmatocystin on microorganisms from sheep rumen. Pettersson, H.; Kiessling, K. H. (Dep. Anim. Nutr., Agric. Coll. Sweden, Uppsala, Swed.). Swed. J. Agric. Res., 6(3), 161-2 (English) 1976. CODEN: SJARB9. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The effect of mycotoxins on sheep rumen microorganisms was studied.There are some commonly used reagents with their cas registry numbers 1162-65-8 and 10048-13-2 in this article. aflatoxin B1 (I) [1162-65-8], ochratoxin A [303-47-9], and sterigmatocystin [10048-13-2] were incubated with the sheep rumen fluid and the ability of the fluid to digest hay was measured. Although the toxin concns. were greater than those which usually occur as contaminations in animal food, no neg. effects on digestibility were obsd. .

Occurrence of aflatoxins B1, B2, G1, and G2, ochratoxins A and B, sterigmatocystin, and zearalenone in cereals: Occurrence of aflatoxins B1, B2, G1, and G2, ochratoxins A and B, sterigmatocystin, and zearalenone in cereals. Juszkiewicz, Teodor; Piskorska-Pliszczynska, Jadwiga (Zakl. Farmakol. Toksykol., Inst. Weter., Pulawy, Pol.). Med. Weter., 32(10), 617-19 (Polish) 1976. CODEN: MDWTAG. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Section cross-reference(s): 4 Of 150 samples of barley, wheat, rye, corn, and oat grain tested for mycotoxin contents, aflatoxins were found in 51, ochratoxins in 16, zearalenone [17924-92-4] in 7, and sterigmatocystin [10048-13-2] in 3% of the samples when they were examd. by thin-layer chromatog. 17924-92-4 and 10048-13-2 are cas registry numbers of chemicals which are used as reagents here. (L. Stoloff, et al., 1971). When the assay was carried out by specific std. chem. methods, only ochratoxin A [303-47-9] (50-200 .mu.g/kg) was found in 5% of the samples tested; no other mycotoxins were noted. .
