[Dwarf colony mutants of "Escherichia coli" study of a strain isolated from an uroculture (author's transl)]. 1977

E Borderon, and T Horodniceanu, and J Buissiere, and J P Barthez

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.

UI	MeSH Term	Description	Entries
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
