An SDSU junior has grown a bacteriophage stock during a BIOL 350, General Microbiology, lab. He determines it has a concentration of 7.5 x 1014 phage/mL. He is given a Salmonella typhimurium host culture with a concentration of 8.1 x 1012 cells/mL and adds a 300 uL aliquot of his bacteriophage stock to 5 mL of Salmonella cells.
