| Abstract | ||
| This study was conducted to investigate the bactericidal effect of aqueous and ethanol extracts of Spirulina platensis and Nigella Sativa on some fish pathogenic bacterial Gram-negative bacteria (Aeromonas hydrophila A. sobria, Flavobacterium columnare, Vibrio Parahaemolyticus) Gram-positive bacteria (Enterococcus fecalis and Streptococcus dysgalactia). The results obtained revealed that aqueous extract of Spirulina platensis has no antibacterial effect on both Gram-positive and Gram-negative bacteria. Ethanol extract of Both Spirulina platensis and Nigella sativa have Enterococcus fecalis and Streptococcus dysgalactia as well as Aeromonas hydrophila A. sobria, Flavobacterium columnare, Vibrio Parahaemolyticus. Besides E. fecalis was more sensitive to ethanol extract than other bacteria. | ||
