Final answer:
Non-bullous impetigo is a contagious skin infection that causes honey-colored crusted lesions, and it can be caused by either Staphylococcus aureus or Streptococcus pyogenes.
Step-by-step explanation:
In non-bullous impetigo, the skin infection begins as a red macule or papule and evolves into vesicles that rupture, leading to the formation of honey-colored crusts typically seen around the nose and mouth. This type of impetigo can be caused by Staphylococcus aureus, Streptococcus pyogenes, or both in combination. It is also relevant to note that S. aureus can cause purulent skin infections that progress from folliculitis to more severe conditions like furuncles and carbuncles.
Staphylococcus aureus is also known for producing leukocidins, which result in pus formation in these skin infections. In comparison, S. pyogenes may lead to various skin conditions such as cellulitis, erysipelas, and erythema nodosum, which present with different types of skin inflammations. Hence, non-bullous impetigo can be attributed to either A) Streptococcus pyogenes or B) Staphylococcus aureus.
