Abstract

Minimum inhibitory concentrations (MICs) of eight antimicrobial agents were tested for 11 Ornithobacterium rhinotracheale isolates and for one type strain. Of the eight antibiotics examined, oxytetracycline was the most active antibiotic with MIC ranges of < or = 0.125 - 1 μg/ml for O. rhinotracheale isolates. All isolates were resistant to gentamicin and neomycin. Resistance to doxycycline occurred only in the type strain. All other isolates were found to be sensitive to doxycycline. Tilmicosin (MICs ranging from < or = 0.5 - 4 μg/ml), erythromycin (MICs ranging from < or = 0.5 - 8 μg/ml), and penicillin G (MICs ranging from < or = 4 - 16 μg/ml) gave good inhibitions, but with most strains in a higher concentration.
