FIG 2.
Alterations in muscle regeneration after experimental infection with a sublethal inoculum of C. perfringens. Groups of 3 CD-1 mice were injected intramuscularly with 1 × 106 CFU of C. perfringens, and muscle sections from samples collected at 7, 14, and 30 days were stained with HE. The inset at 7 days shows regenerative cells with central nuclei; asterisks indicate the presence of cellular debris embedded in a fibrous matrix at different times. Bars, 100 μm.
