title: [Dwarf colony mutants of "Escherichia coli" study of a strain isolated from an uroculture (author's transl)].
abstract: A dwarf colony mutant of Escherichia coli was isolated from the urine of a patient with an asymptomatic urinary infection. This dwarf mutant growths poorly (minute transparent colonies) on Trypticase Soja and Mueller-Hinton agar, and requires thiamine concentration of 3 x 10-11 M.
