Florfenicol is a synthetic fluorinated analog of thiamphenicol that exhibits antibiotic activity in livestock. Florfenicol acts as an antibacterial against Shigella, Escherichia, Klebsiella, Enterobacter, and Haemophilus. Florfenicol binds 23S rRNA on the bacterial 50S ribosome, inhibiting translation.
