Figure 3. Growth characteristics of C. trachomatis L2 and C. trachomatis L2 transformed by pBR325::L2.

Figure 3

(A) C. trachomatis L2/434/Bu, (B) C. trachomatis L2/434/Bu transformed by shuttle vector pBR325::L2. McCoy cells in a 24 well tissue culture tray grown to confluence were infected with C. trachomatis at MOI  = 1 and were cultured without (-PEN) and with (+PEN) penicillin G at 10 units/ml. The yield of C. trachomatis (IFU) per culture or single well is shown on the y – axis and time of sampling post infection is shown on the x –axis. The experiments were repeated in quadruplicate and standard error bars are shown for each sample point.
