| Discovery Information | |
| Isolation Host | Arthrobacter globiformis NRRL B-4425 |
| Former names | GeeGee |
| Found By | Jacob Knickle |
| Year Found | 2025 |
| Location Found | Ottawa, Canada |
| Finding Institution | University of Ottawa |
| Program | Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science |
| From enriched soil sample? | No |
| Isolation Temperature | 30°C |
| GPS Coordinates | 45.42574 N, 75.67047 W Map |
| Discovery Notes | The environmental sample was collected from the Ottawa River riverbank. The soil was waterlogged, sediment-rich, and muddy. The ambient temperature at the time of collection was 18 °C. Nanopore sequencing of the isolated phage genome resulted in two contigs, one of which was 59 kb in length. BLASTn alignment showed a hit with 92% query cover, 99% identity, and an E-value of 0 to Zippen, a lytic AU7 Siphoviridae phage discovered in 2024 in Ottawa through the SEA-PHAGES program. These results suggest that Strava likely shares strong genomic similarities with Zippen. |
| Naming Notes | The phage was named Strava, inspired by the running application, as the soil sample was collected near a frequent running path along the Rideau River. |

| Plaque Notes | The isolated bacteriophage Strava formed small, clear plaques on the Arthrobacter globiformis lawn, indicating a lytic phage. The small plaque size may reflect a relatively low diffusion rate or a smaller burst size. Throughout the purification period, Strava demonstrated high infectivity and strong viral persistence, consistently producing plaques even on A. globiformis cultures that appeared more resistant than previous batches. This may suggest that Strava possesses a high infection capability and remains effective across varying host conditions. |
