A farmer working on a piece of machinery gets his shirtsleeve
caught in a moving piece of the equipment. His shirt is sliced, and
a sharp blade covered in mud slices through his upper arm. He
attempts to control the bleeding and immediately seeks medical
attention. After 3 days, he develops a fever and his arm becomes
extremely swollen and painful. Pulling back the bandages, he finds
that the wound has become blackened and is leaking bloody fluid.
Microscopic analysis of the fluid reveals the presence of
gram-positive bacilli.
a. Discuss what condition the patient is suffering from and the
likely causative agent of this infection.
b. Explain how the patient contracted this pathogenic microbe
and what virulence factors contributed to the pathogenesis seen at
the wound site.
c. In addition to antibiotics, the physician prescribes
hyperbaric therapy. Describe what this treatment involves and how
it could be therapeutic to this patient.
