The Identification of Intrinsic Chloramphenicol and Tetracycline Resistance Genes in Members of the <i>Bacillus cereus</i> Group (<i>sensu lato</i>).

ABSTRACT: Bacillus toyonensis strain BCT-7112^T (NCIMB 14858^T) has been widely used as an additive in animal nutrition for more than 30 years without reports of adverse toxigenic effects. However, this strain is resistant to chloramphenicol and tetracycline and it is generally considered inadvisable to introduce into the food chain resistance determinants capable of being transferred to other bacterial strains, thereby adding to the pool of such determinants in the gastro-enteric systems of livestock species. We therefore characterized the resistance phenotypes of this strain and its close relatives to determine whether they were of recent origin, and therefore likely to be transmissible. To this end we identified the genes responsible for chloramphenicol (catQ) an
