Constancy of diameter through the cell cycle ofSalmonella typhimurium LT2

1982

Measurements of cell diameter and length inSalmonella typhimurium LT2 cells were correlated using both light and electron microscopy. In cultures growing at high, intermediate, and low rates, cell diameter does not change with length. This constancy is also maintained in septated cells before division. Since length increases continuously with cell age, the above observations mean that cells maintain a constant diameter during the cell cycle.
