Abstract
Enrichment with D-cycloserine was used to identify Escherichia coli au xotrophic mutants that exhibited limited growth in human urine. Bacter ial synthesis of guanine, arginine, and glutamine was found to be requ ired for optimal growth in urine, Mutants that required leucine, methi onine, serine, phenylalanine, or proline also exhibited reduced growth in urine, Several other nutritional mutants, including nicotinamide a uxotrophs, which are found frequently among cystitis isolates, exhibit ed normal growth in urine.
