During one week, a 7-year boy develops pustules on his face. Then, some of the pustules break,
forming shallow erosions in appearance of a honey-colored crust. Next, new lesions form around the
crust. The boy’s¬ father has similar lesions after one week of the son’s illness. The Gram stain from a
skin pustule showed gram positive in grape-like clusters. The colonies were catalase positive. What
is the most likely microorganism?
