Drug Type: Antibiotic


Florfenicol is a type of antibiotic that is classified within the amphenicol group of antibiotics. It is used most often to treat pneumonia in chickens. Florfenicol is effective against a number of many Gram-negative and Gram-positive organisms, including certain chloramphenicol-resistant strains of Escherichia coli, Salmonella typhimurium and Staphylococcus aureus. Florfenicol works by suppressing the protein synthesis through inhibiting the peptidyl transferase enzyme in addition to the ribosomal translocation.

Caution: Recent research shows that florfenicol is toxic to developing chick embryo at around day 5 of incubation. Chickens treated with florfenicol may likely experience decreased hatachability for a week following treatment with florfenicol.
