[Isolation of thymidine-dependent strains. Microbiologic considerations and personal observations].
We describe the emergence of three thymidine-dependent strains (Thy-): two Escherichia coli obtained in successive occasions from urine of a woman treated with co-trimoxazole before the organisms were isolated and one Proteus mirabilis obtained from urine of a man who had a treatment with norfloxacin. Cultural characteristics and methods for the detection of these Thy- strains are given.
