The Antibacterial Effects of Çiriş (Asphodelus aestivus Brot.) on Some Foodborne Pathogenic Bacteria

Öz

This study aimed to determine the antibacterial effects of Çiriş (Asphodelus aestivus Brot.) on eight important food-borne pathogenic bacteria by the disc diffusion method. The highest inhibition effect was determined on Escherichia coli with a 15.63 mm zone diameter, followed by, Staphylococcus aureus (14.78 mm), Listeria monocytogenes (10.72 mm), Shigella flexneri (10.06 mm), Enterobacter aerogenes (9.22 mm) and Enterococcus feacalis (8.15 mm) (P<0.05). On the other hand, Çiriş showed the lowest inhibition effect on Salmonella Typhi and Salmonella Typhimirium, with 7.28 and 6.42 mm zone diameters, respectively. Comparing the data obtained to the effects of the standard antibiotics on the same pathogens, it was found that Escherichia coli were susceptible while Staphylococcus aureus and Shigella flexneri were moderately susceptible to the ethanol extract of Çiriş. On the other hand, it was determined that Salmonella Typhi, Listeria monocytogenes, Enterococcus feacalis, Salmonella Typhimirium, and Enterobacter aerogenes exhibited resistance.

Çirişin (Asphodelus aestivus Brot.) Bazı Gıda Kaynaklı Patojen Bakteriler Üzerindeki Antibakteriyel Etkisi

Öz

Bu araştırmada çirişin (Asphodelus aestivus Brot.) sekiz önemli gıda kaynaklı patojen bakteri üzerindeki antibakteriyel etkisinin disk difüzyon metodu ile belirlenmesi amaçlanmıştır. Araştırma sonucunda en fazla inhibisyon etkinin; 15.63 mm zon çapı Escherichia coli üzerinde olduğu, bunu sırasıyla Staphylococcus aureus (14.78 mm), Listeria monocytogenes (10.72 mm), Shigella flexneri (10.06 mm), Enterobacter aerogenes (9.22 mm) ve Enterococcus feacalis (8.15 mm) takip ettiği belirlenmiştir (P<0.05). Buna karşın en düşük inhibisyon etkinin ise; sırasıyla 7.28 ve 6.42 mm zon çaplarıyla Salmonella Typhi ve Salmonella Typhimirium üzerinde olduğu gözlemlenmiştir. Elde edilen veriler aynı patojenler üzerinde standart antibiyotiklerin etkileri ile kıyaslandığında çirişin etanol ekstraktına karşı; Escherichia coli’ nin duyarlı, Staphylococcus aureus ve Shigella flexneri’nin orta duyarlı olduğu belirlenmiştir. Buna karşın; Salmonella Typhi, Listeria monocytogenes, Enterococcus feacalis, Salmonella Typhimirium ve Enterobacter aerogenes’in ise, dirençli olduğu tespit edilmiştir.
