Antibiotic susceptibility results for two F. spartansii isolates as determined via the Kirby-Bauer disk diffusion method.
| Isolate | SXT | PB | P | O129 | FFC | AMP | E | T |
|---|---|---|---|---|---|---|---|---|
| T16 | I (11.5) | I (10.5) | R (6.0) | R (6.0) | I (16.0) | R (9.0) | I (18.0) | I (17.0) |
| S12 | I (14.0) | I (11.0) | R (6.0) | R (6.0) | I (17.0) | I (12.0) | S (18.5) | I (16.5) |
R, resistant; I, intermediate sensitivity; S, sensitive. Number in parentheses denotes the mean diameter (in mm) of the zone of inhibition. SXT, trimethoprim-sulfamethoxazole (25 μg); PB, polymyxin-B (300 iu); P, penicillin G (10 iu); O129, 2,4-diamino,6,7-di-isopropyl pteridine (10 μg); FFC, florfenicol (30 μg); AMP, ampicillin (10 μg); E, erythromycin (15 μg); T, oxytetracycline (30 μg).
