title: Hydrazines as mutagens in a histidine-requiring auxotroph of Salmonella typhimurium.
abstract: Hydrazines have been found naturally in tobacco and mushrooms. Other hydrazines are used in industry, medicine, and agriculture. Although about 38 hydrazines are carcinogenic, few, if any, have been tested successfully in rapid bacterial mutagenesis assays. We have utilized a tester strain of Salmonella typhimurium (TA1530) in order to determine the mutagenic activity of a number of hydrazines and related compounds. This strain is thus shown to be effective as a tester organism for the facile detection of hydrazines as mutagens.
