Susceptibility of Y. enterocolitica strain JB580v and GY448 to ampicillin and spectinomycin. Strains GY123 (WT), GY448 (csrA), GY6536 (VC) and GY6535 (csrA/csrA+) were cultured and bacteria were spread onto TYE agar medium. A disk containing A) 100 mg/ml ampicillin or B) 50 mg/ml spectinomycin was placed in the center of the plate. After incubation at 26°C for 48 hours, the diameter of the zone of growth inhibition around the disk was measured. Results represent averages ± standard deviation from three independent experiments performed in duplicate. *The p-value compared to WT was < 0.0001.
