They are rare pathogens in humans but seem to be problematic in livestock.

This part made me come up with a story: a person that is involved in food production, livestock breeding, and logistics that happen to be immunocompromised caused by another disease process and got this as an opportunistic infection. Male, working age group, and wounds on the limb extremities. An alternative story is the patient already immunocompromised and got contaminated by some that is within the line of work mentioned above.

It's just one of the silly techniques my consultants used to teach me in medschool where we create stories that are close to textbook examples and what the patient has to help include or exclude possible angles to diagnose during history taking.

Still can't get over the part where I missed the variability in sizes and just reflexively called in under the Staph spp.
