Common NameEnrofloxacin
DescriptionEnrofloxacin is a veterinary antibacterial agent, used in poultry. Enrofloxacin is a fluoroquinolone antibiotic sold by the Bayer Corporation under the trade name Baytril(r). Enrofloxacin is currently FDA-approved for treatment of individual pets and domestic animals in the United States. In September 2005, the FDA withdrew approval of Baytril for use in water to treat flocks of poultry, as this practice was noted to promote the evolution of fluoroquinolone-resistant strains of the bacterium Campylobacter, a human pathogen. Fluoroquinolones such as ciprofloxacin are widely used in the treatment of human disease. Enrofloxacin is a synthetic chemotherapeutic agent from the class of the fluoroquinolone carboxylic acid derivatives. It has antibacterial activity against a broad spectrum of Gram-negative and Gram-positive bacteria. Its mechanism of action is not thoroughly understood, but it is believed to act by inhibiting bacterial DNA gyrase (a type-II topoisomerase), thereby preventing DNA supercoiling and DNA synthesis. It is a bactericidal agent. The bactericidal activity of enrofloxacin is concentration dependent, with susceptible bacteria cell death occurring within 20-30 minutes of exposure. Enrofloxacin has demonstrated a significant post-antibiotic effect for both Gram-negative and Gram-positive bacteria and is active in both stationary and growth phases of bacterial replication. http://www.fda.gov/cvm/Documents/baytrilDDL.pdf is a broken lin
