Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne. Explain mechanistically how can a bacterium be normal and beneficial but also be pathogenic?
A 55-year-old woman with type 2 diabetes mellitus comes to the physician with a 2-day history of oozing, foul-smelling wound on her foot. Physical
examination shows a 4-cm, necrotizing wound on the heel with purplish black discoloration of the skin around the wound, and crepitant bullae producing
thin, serous fluid. A Gram stain of tissue biopsy from the site shows gram-positive rods. Which of the following toxins is produced by the most likely
causal organism?
Answers A-E
Alpha toxin
B Endotoxin
C Exfoliative toxin
D Exotoxin A
