Celery (Kelussia odoratissima) is a native plant of Iran along with anti-bacterial effects. This study aimed to compare the efficacy of anti-bacterial antibiotics with Ethanol extract of celery against four strains of Streptococcus iniae isolated from rainbow trout. In this regard, five treatments with different concentrations of 6.25, 12.5, 25, 50 and 100 µg/µl of extracts was developed. Then, Well Diffusion and Discs on Mueller Hinton methods were used to determine the antibacterial activity. Collected data were statistically analyzed using one-way ANOVA and the significant level of p< 0/05. The results showed that ethanol extract of celery in concentrations of 6.25 and 12.5 µg/µl had no effect on the studied bacteria. Also, there is no bacteria inhibition zone in bacteria concentration of 25µg/µl in 3, 4 bacterial isolates addition to 6/25 and 12/5 µg/µl. The most bacteria inhibition zone diameters were respectively recorded 19.33, 19.33, 18.67 and 15.33 mm that showed the difference between different concentrations (p<0.05).
