FIG. 4.
Resistance of S. enteritidis isolates to ASN. Resistance was measured by the survival rate, which equals (CFU of bacteria after incubation in ASN/CFU of bacteria before incubation) × 100. (A) Survival of bacteria after 3 h of incubation; (B) survival of bacteria after 6 h of incubation. Results from a single representative experiment performed in triplicate are presented. Error bars indicate standard deviations.
