FIG. 4.

Incorporation of [¹⁴C]serine into phospholipids of mock-infected mouse L cells (A) and C. trachomatis-infected mouse L cells (B) in the absence (open bars) and presence (hatched bars) of 20 μM fumonisin B₁. Fumonisin B₁ was added at the start of the infection (2 h p.i.), and radiolabelled serine was added at 20 h p.i. The cells were harvested 5 h later. Results are expressed as means ± standard deviations of results from three separate experiments.
