Abstract
Selective enrichment media and methods for selectively growing and detecting Salmonella spp. and/or Shiga toxin-producing E. coli. The media may comprise a carbon and nitrogen source, an inorganic salt, a fermentable sugar, one or more selective agents, and an efflux pump inhibitor. Various selective agents include sulfa drugs, surfactants, aminocoumarins, cycloheximide, supravital stains, ascorbic acid, bromobenzoic acid, myricetin, nitrofurantoin, rifamycins, polyketides, and oxazolidinones. Various efflux pump inhibitors include arylpiperazines, such as 1-(1-naphthylmethyl)piperazine, and quinoline derivatives, such as 4-chloroquinoline. Methods of selectively growing and detecting Salmonella and/or Shiga toxin-producing E. coli are provided.
