Identification of Gram-positive cocci: You have isolated a catalase-negative bacterium that doesn't grow well in 6.5% NaCl medium. Which test would you expect to give you a presumptive identification? (i.e. The first tests tell you the genus, which test would identify a species of that genus) CAMP Test Coagulase Tube Test PYR Test Novobiocin Sensitivity Test
