Alcohol-induced conditioned aversion: genotypie specificity in mice (Mus musculus).
Acetaldehyde poisoning from ethanol ingestion may lead to aversion to ethanol among DBA mice but not among C57s, since the former are relatively deficient in aldehyde dehydrogenase activity. The present study paired ingestion of saccharin with a single intraperitoneal injection of one of four concentrations of ethanol for DBA/2J and C57BL/6J mice. Subjects were then given a two-bottle saccharin versus water preference test for 10 days. Substitution of saccharin for the taste of ethanol resulted in avoidance of saccharin with all concentrations of ethanol by DBAs but not by C57s, consistent with the conditioned taste aversion paradigm as a model for genetically mediated ethanol avoidance.
