Mellissa and Alex have been experimenting further with phage to continue this collaboration, below are experiments conducted at Oxford University in October 2017.
“We prepared several litres of LB agar (a bacterial growth medium originally developed to work with bacteria and phages) and poured the molten agar into the moulds prepared previously by Mellissa. Once set, the sculptures were inoculated with bacteria, specifically Pseudomonas aeruginosa (a leading cause of Pneumonia in hospitals). We also added some phage (viral parasites that kill bacteria) which had been obtained from as pharmacy in Tbilisi (Georgia) as part of a therapeutic to treat infection. The bacteria have the handy property of fluorescence in UV light that allows a clear visualisation of bacterial growth. After incubating the sculptures at body temperature overnight we illuminated them to see the results.”
