Discovery NotesSoil was collected from a damp creekbed in the woods near Lexington, GA. Soil was sandy and waterlogged, although the creek had dried up in patches and was not actively flowing at time of collection.

Phage was initially isolated on an equal-parts mix of four different Arthrobacter strains (A. globiformis B-2979, A. pascens B-1814, A. globiformis B-4425, A. humicola B-24478). After initial purification, the phage was found to plaque only on A. pascens 1814 A and A. globiformis B-4425. Subsequent stages of purification were done only with A. pascens B-1814.

Prior to naming, this phage was designated “S2.5” throughout isolation and purification.

Isolated in the lab of Dr. Nic Vega.
Naming NotesOrmyrus is a genus of chalcid wasps, most of which are specialized parasitoids of gall-forming insects. I have developed a great interest in oak galls induced by Cynipid wasps, and recently attempted to rear some oak galls that I collected on Emory’s campus. I was surprised to find that most (maybe all?) of the wasps that emerged were parasitoids. Among these impostor wasps was a very beautiful Ormyrus individual. Seeing this, I was inspired to confer the name of this parasitoid onto another much smaller but surely no less beautiful parasitoid.
