a
The long axes of the cell bodies of individual bacteria were measured. The data are reported as percentage of the populations (± standard error) that had bodies between the indicated lengths.
b
The strain was grown with 15 µg/ml cephalexin for 6 hours before analysis.
c
The strain was grown with 12.5 µg/ml cephalexin for 6 hours before analysis.
