Marbofloxacin is a veterinary fluoroquinolone antibiotic known for its efficacy against a wide range of Gram-negative and Gram-positive bacteria in animals. It belongs to the third-generation fluoroquinolone class and is commonly used in veterinary medicine for the treatment of bacterial infections in companion animals, livestock, and poultry. Marbofloxacin demonstrates potent activity by inhibiting bacterial DNA gyrase and topoisomerase IV enzymes, essential for bacterial DNA replication and transcription processes. It is available in oral and injectable formulations, making it versatile for the management of respiratory, urinary, and skin infections in veterinary practice.
