| Discovery Notes | The phage was discovered in an environmental sample, collected from a flower pot in a humid, nutrient-rich environment. The slightly moist soil and organic matter likely favored bacterial growth, creating ideal conditions for phage presence. Following the direct isolation procedure, three distinct plaques were observed, confirming the presence of a phage capable of infecting the host strain. |
| Naming Notes | I named my phage Jessous as a creative variation of my last name, Guessous. It’s a nickname people have used for me for years, pronounced with a soft “J” like in Spanish. Beyond being personal, the name represents connection,between identity and discovery, between the scientist and the phage,reminding me that every finding in science carries a bit of its discoverer’s story.Naming my phage Jessous felt fitting,it’s a small but unique organism I discovered myself, just like this nickname uniquely represents me. |

| Plaque Notes | Three plaques were observed on the bacterial lawn, all small, clear, and uniform in appearance. Their reduced size suggests a longer lysis time, indicating a phage that completes its infection cycle more slowly, resulting in localized zones of infection. The plaques have well-defined edges and complete clarity, reflecting efficient bacterial lysis and a homogeneous phage population. Overall, the morphology is characteristic of a lytic phage with strong but controlled infectivity. |
