FIG. 1.

Incorporation of [U-¹⁴C]isoleucine into glycerophospholipids of C. trachomatis-infected wild-type CHO K1 (A) and thermolabile CDP-choline synthetase CHO strain 58 (B) cells at 33°C (open bars) and 40°C (hatched bars). The host cells were held at their respective temperatures for 60 h prior to infection. The temperature was maintained after infection. Infected cultures were radiolabelled at 20 h p.i. and harvested 5 h later. The results for each phospholipid are expressed as percentages of the total radioactivity incorporated into phospholipids. CL, cardiolipin. Results are expressed as means ± standard deviations of results from three separate experiments.
