Figure 4. Accumulation of PpIX in MRSA after intraperitoneal injection with 5-ALA.

Figure 4

(A) Cutaneous skin ulcers with (right) or without (left) MRSA. (B) Strong red fluorescence was detected in MRSA-infected ulcers 24 h after intraperitoneal injection of 200 mg/kg 5-ALA and irradiation with a Wood’s lamp (right). (C) Transmission image of a smear on a cutaneous ulcer infected with MRSA after intraperitoneal injection of 5-ALA. (D) Confocal laser scanning microscopy of PpIX fluorescence in MRSA. 405-nm diode, ultraviolet light, emission bandwidth 620–650 nm.
