Partial hydrolysis of dieldrin by Aerobacter aerogenes Partial hydrolysis of dieldrin by Aerobacter aerogenes
Although dieldrin (1,2,3,4,10,10-hexachloro- 6,7-epoxy-1 ,4 ,4a ,5 ,6 ,7 ,8, 8a-octahydro-1 ,4-endo, exo-5, 8-dimethanonaphthalene) metabolism by mammals (F. Korte and H. Arent, Life Sci. 4:2017, 1965) and insects (D. F. Heath and M. Vanderkar, Brit. J. Ind. Med. 21:269, 1964) has been reported, little is known about the degradation of this important pesticide by microorganisms. Korte et...

Dietary factors and hepatoma in rainbow trout (Salmo gairdneri). I. Aflatoxins in vegetable protein feedstuffs Dietary factors and hepatoma in rainbow trout (Salmo gairdneri). I. Aflatoxins in vegetable protein feedstuffs
Aflatoxins (toxic metabolites of the mold Aspergillus flavus) were present in a commercial trout ration causing hepatoma in rainbow trout. Cottonseed meal and solvent extracts of cottonseed meal and of rations containing cottonseed meal and peanut meal were found by chemical assay and confirmed by duckling assay to contain aflatoxins. Diets containing these materials and a purified test...

Role of intestinal microflora in the degradation of DDT by rainbow trout (Salmo gairdneri) Role of intestinal microflora in the degradation of DDT by rainbow trout (Salmo gairdneri)
Though liver homogenates show apparent microsomal enzyme DDT-dehydrochlorinase activity, in the intact fish the intestinal microflora play a major role in DDT detoxication. Since the presence of this microflora in fish depends on the recent intake of food (12), the rate of detoxication and hence the toxicity of ingested DDT to the rainbow trout will probably depend somewhat on the...

Nutritionally induced hepatomagenesis of rainbow trout (Salmo gairdneri) Nutritionally induced hepatomagenesis of rainbow trout (Salmo gairdneri)
Hepatoma in commercially reared rainbow trout (Salmo gairdneri) was first seen at this laboratory in April of 1960. The subsequent discovery of it in near epizootic proportions in other hatchery-reared rainbow trout and cutthroat trout (S. clarki) populations throughout the United States precipitated extensive research by numerous agencies. Although the liver neoplasm in trout had been...
A comparison of Oregon pellet and fish-meat diets for administration of sulfamethazine to Chinook salmon A comparison of Oregon pellet and fish-meat diets for administration of sulfamethazine to Chinook salmon
The absorption of sulfamethazine by yearling spring chinook salmon (Oncorhynchus tshawytscha) was compared when administered in the Oregon Pellet and a fish-meat diet. The pelleted diet delivered the drug to the fish approximately twice as efficiently as the fish-meat diet. Dosage levels are recommended for both diets, and the efficacy of administering drugs in fish feed is discussed.

Biodegradation of dichlorodiphenyltrichloroethane: Intermediates in dichlorodiphenylacetic acid metabolism by Aerobacter aerogenes Biodegradation of dichlorodiphenyltrichloroethane: Intermediates in dichlorodiphenylacetic acid metabolism by Aerobacter aerogenes
The final product of dichlorodiphenyltrichloroethane (DDT) degradation by vertebrates is commonly considered to be dichlorodiphenylacetic acid, DDA (J. E. Peterson and W. H. Robison, Toxicol. Appl. Pharmacol. 6:321, 1964). Recently, certain organisms (A. S. Perry, S. Miller, and A. J. Buckner. J. Agr. Food Chem. 11:457, 1963; J. D. Pinto, M. N. Comien, and M. S. Dunn. J. Biol. Chem. 240...
