Staphylococcus aureus.
Question 1
Henry, 64 years old, is having difficulty getting rid of a corneal infection. He asks why. How do you respond?
“Systemic antibiotics have difficulty getting to that area of the eye.”
“Because the cornea doesn’t have a blood supply, an infection can’t be fought off as usual.”
“Because the infection was painless, it was not treated early enough.”
“We can’t determine the causative agent.”
Question 2

What is the most likely pathogen causing these lesions?
Staphylococcus aureus.
Streptococcus.
Pseudomonas aeruginosa.
Klebsiella.
