Antibacterial activity of marbofloxacin. A new fluoroquinolone for veterinary use against canine and feline isolates.
Marbofloxacin is a new fluoroquinolone developed exclusively for veterinary use. Minimum inhibitory concentrations of marbofloxacin were assessed for 816 recent isolates associated with canine or feline diseases. Marbofloxacin showed a broad spectrum of activity against gram-negative and gram-positive bacteria. In vitro rates of killing of marbofloxacin and enrofloxacin were compared against strains of Staphylococcus intermedius and Pasteurella multocida, and the results showed no marked difference between the two antibiotics. The duration of bactericidal activity was evaluated ex vivo in the urine of dogs and cats treated with marbofloxacin and lasted from 2 to 5 days after a single administration according to the dosages. Post-antibiotic effect durations were determined with Escherichia coli, Pasteurella multocida, Staphylococcus aureus and Staphylococcus intermedius and were found almost equal to those of enrofloxacin or ciprofloxacin. These results predict a great potential for marbofloxacin in the treatment of a wide range of diseases in dogs and cats.
