Values represent the lytic activity of the respective phage against the target bacterium. EPEC (enteropathogenic E. coli), EHEC (enterohemorrhagic E. coli), ETEC (enterotoxigenic E. coli), EIEC (enteroinvasive E. coli), EAEC (enteroaggregative E. coli), UPEC (uropathogenic E. coli). EOP was calculated using double agar overlay method. EOP was deemed as ‘High’ if the test bacterium had at least 50% activity (EOP ≥ 0.5) compared to the host bacterium, ‘Moderate’ if between >10 and <50% (EOP > 0.1- < 0.5), anything < 10% (EOP ≤ 0.1) was reported as ‘Low.’
