Abstract :Antibacterial activities of 24 alcoholic and aqueous extracts from 8 endemic Turkish plants insert ignore into journalissuearticles values(Crocus abantensis, Crocus ancyrensis, Galanthus plicatus subsp. byzantinus, Paronychia chionaea, Astragalus gymnolobus, Trifolium pannonicum subsp.elongatum, Eryngium bithynicum, and Convolvulus galaticus); of 7 different families were screened. Antibacterial activity was carried out with 5 different fish pathogens insert ignore into journalissuearticles values(Aeromonas hydrophila, Yersinia ruckeri, Streptococcus agalactia, Lactococcus garvieae, and Enterococcus faecalis);. Crude extracts of endemic plant extracts were applied against the bacteria using the disc diffusion method under in vitro conditions. A. hydrophila was the only inhibited bacteria from all alcoholic and aqueous extracts of C. ancyrensis, G. plicatus, T. pannonicum, P. chionaea, and A. gymnolobus. The alcoholic extracts of T. pannonicum among all of the plant extracts showed a broad antibacterial spectrum against A. hydrophila, Y. ruckeri, S. agalactia, and L. garvieae except E. faecalis. Among the studied endemic plants, T. pannonicum is a promising source for natural compounds having antimicrobial activity on fish pathogens.
