FIG 9.
TGFB1 expression in mouse gastrocnemius after experimental infection with a sublethal inoculum of C. perfringens. Groups of 4 to 6 CD-1 mice were injected intramuscularly with 1 × 106 CFU of C. perfringens, and the expression of TGF-β1 in infected muscles was measured by RT-PCR (A) and by ELISAs (B) at different times. Controls were injected with sterile PBS. Results show means ± SE. *, P < 0.01; **, P < 0.05 (for samples with a statistically significant difference compared with the control).
