Sığır Fekal Örneklerinden Salmonella spp. ve Escherichia coli O157:H7’ye Özgü Bakteriyofaj Varlığının Araştırılması

Abstract

S. Typhimurium and E. coli O157:H7 are the most important foodborne pathogens forming bacterial biofilms that contribute to their virulence, antimicrobial resistance, and surface survival, causing severe food poisoning outbreaks worldwide. Bacteriophages are antibacterial agents that are increasingly used to control foodborne pathogens, and they also play a role in the solution against the development of antibiotic resistance. In addition, bacteriophages can be found in wastewater, natural and animal wastes, and foodstuffs. Aim of this study to determine the purification and lytic effects of Salmonella spp. and E. coli specific phages circulating in our country, which can effectively combat common Salmonella spp. and E. coli infections in our country and the world by using samples taken from the cowshed. In this study, 3 S. Typhimurium and 1 E. coli O157:H5 bacteriophages were isolated, and their lytic activities were determined. As a result, it is thought that the lytic activities of S. Typhimurium and E. coli O157:H7 bacteriophages purified from Aksaray province in this study can shed light on the treatment of S. Typhimurium and E. coli O157:H7 infections and prevention studies in the food industry.
