Abstract
Introduction: Enteropathogenic Escherichia coli (EPEC) strains cause a gastrointestinal disease in the developing countries. Over the years, antimicrobial resistance of EPEC have been a major issue. Bacteriophages have been a therapeutic option for bacterial infection. Our aim was to assay lytic activity of a siphophage on an EPEC strain. Materials and Method: EPEC strain ATCC 43887 was used for phage isolation using by double layer agar method. Bacteriophage morphology was visualized by transmission electron microscope. Result: a siphophage was detected by transmission electron microscope images. The phage formed small clear circular plaques. The results of lytic activity of siphophage on reference EPEC strain showed the phage could lyse the strain. Conclusion: the phage had lytic activity on reference EPEC strain. The phage belonged to siphoviridae family. It look the phage can lyse clinical EPEC strains.
