Please refer to the given scenario below. What is the most appropriate sample to
be collected to isolate the causative agent of the infection? *
A 46-year-old male encountered a motor-vehicular accident (MVA) resulting in
multiple injuries on his anterior chest and left lower extremities. Aside from the injury, his
medical history was unremarkable. The patient was admitted for nine days and underwent
debridement and was discharged with an external fixator. However, during his admission, on
his 7m post-operative day, the wound was noted to have persistent purulent, bloody
discharge from drain site, which is highly suggestive of surgical site infection (SSI).
