Hi Peyton,
The same bacteria was used throughout the experiment. The bacteria was M. smegmatis, which was chosen due to its non-pathogenic nature as well as its close proximity in the phylogenetic tree to multiple pathogenic strains of bacteria. The hope was by using M. smeg to isolate a phage, the phage may also be able to infect the similar pathogenic bacteria and be used in phage therapies to treat antibiotic-resistant infections. Thanks for your question!
What kind of bacteria was present on your plates?
