Discovery NotesMy phage was collected at night from a soil sample 1-inch below the surface outside of the apartment in which I reside. The soil was still slightly moist due to a recent sprinkler cycle.

1X 7H9 Complete was used for enrichment purpose. Contamination was seen in my original spot-test, but was likely a result of my own improper aseptic technique in plating as no contamination was observed in a subsequent spot-test.

Once my phage was isolated, I observed that the plaques it produced were large and somewhat turbid, signifying that I likely isolated a temperate phage.

My calculated phage titer was 6x10^11. However, when sample was observed using electron microscopy, a low quantity of phage was observed. This may signify a phage with a high infection rate, which would explain the high PFU calculation.
Naming NotesThis phage was given the first and middle name of my dog, a little and annoying Cavachon. I felt the name fit perfectly.
