A set of five female BALB/c mice were subcutaneously injected into the inner thigh with either bioluminescent S. aureus Xen 36 (Bac) or a suspension of Xen 36 and quantum dot 705 (Bac + QD). In the same manner, a second set of five female BALB/c mice were subcutaneously injected into the inner thigh with either PS or a suspension of QD 705. The total volume of each injection was identical, and the concentrations of the Xen 36 and QD 705 were kept constant throughout. The mice were observed without a filter (total light) and through a 695–770 nm filter, from the ventral and the dorsal side in an IVIS100. Values indicate the mean photon·s^-1·cm^-2 ± SEM, n = 5.
