Changes in cell size and shape in thymine-requiring Escherichia coli associated with growth in low concentrations of thymine. 1978

K J Begg, and W D Donachie

Thymine auxotrophs of three unrelated strains of Escherichia coli (K-12, B/r, and 15) were grown in media containing various concentrations of thymine. During steady-state growth conditions, cell volume increased as thymine concentration decreased but, in contrast to previous reports, this change was due to an increase in cell length without change in cell diameter.

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
