Natural Toxins: Animal, Plant and Microbial

Abstract

The following were among the papers presented at the 5th International Symposium on Animal, Plant and Microbial Toxins, held in San Jose, Costa Rica, in Aug. 1976:Buchanan, J.R.; Sommer, N.F. High-pressure liquid chromatography in the identification and analysis of mycotoxins in foodstuffs (703-711, 10 ref., 7 fig.).Chu, F.S. Mycotoxin-macromolecule bindings (713-728, 60 ref., 1 fig., 3 tab.).Ciegler, A. Detoxification of aflatoxin-contaminated agricultural commodities (729-738, 47 ref.).Hayes, A.W. Mycotoxin teratogenicity (739-758, 30 ref., 11 tab.).Leon-Cazares, J.; Aroche-Alfonso, R.M.; Cuetos-Martinez, C.B. Effects of several mycotoxins on the chromosomes of human lymphocytes in vitro (759-765, 10 ref., 2 fig., 3 tab.). Initial studies are reported regarding the effect of 3 compounds from Aspergillus tamarii on human lymphocytes.Lin, J.-K.; Miller, J.A; Miller, E.C. Studies on the characterization of the hepatic nucleic acid-bound forms of aflatoxin B1 in the rat (767-777, 40 ref., 3 fig.).Llewellyn, G.C.; Thomen, L.E. Body weight changes and corresponding pathological responses seen in Syrian hamsters and Mongolian gerbils fed aflatoxin B1 (779-789, 21 ref., 4 fig., 1 tab.).Ong, T.-M. Aflatoxin mutagenesis in Neurospora crassa (791-799, 20 ref., 7 tab.).Richard, J.L.; Thurston, J.R.; Pier, A.C. Effects of mycotoxins on immunity (801-817, 67 ref., 4 tab.).Sommer, N.F.; Buchanan, J.R. Mycotoxin production by postharvest pathogens of fruits and vegetables (819-828, 18 ref., 1 fig., 2 tab.). Studies are described on the effects of atmospheric modification and temps. on the synthesis of patulin in apple fruits and on suppression of the causal fungus, Penicillium expansum and the relation of temp. management and handling practices to suppression of the toxic fungus Alternaria alternata in chill-sensitive fruits. Various approaches to the control of mycotoxin-producing fungi to prevent infection or limit fungus activity after infection are examined and discussed.Acuna, D.; Benavides, J.; Vega, N.; Campbell, A.D. Analytical method for aflatoxinsin corn samples contained with levels up to 1000 μ g/kg (855).Ling, K.-H. Blue fluorescent compounds isolated from the semi-synthetic media of Aspergillus terreus (885-856).
