In vitro antibiotic sensitivity of strains of Ornithobacterium rhinotracheale isolated in The Netherlands between 1996 and 1999.
All the strains of Ornithobacterium rhinotracheale isolated in the Netherlands between 1996 and 1999 were tested in the agar gel diffusion test for their sensitivity to amoxycillin, tetracycline, enrofloxacin and trimethoprim/sulphonamide (TMP/S). The percentages of strains sensitive to amoxycillin and tetracycline decreased in successive years from approximately 62 per cent to 14 per cent, and four strains were resistant to enrofloxacin or TMP/S. Twelve multiresistant strains were tested against seven alternative antibiotics; they were resistant to all of them except clavulanic acid-potentiated amoxycillin.
