Question

The likely causative organism of nonbullous impetigo in a 6 year old child include:

A. H. influenza and S. pneumoniae
B. Group A streptococcus and S. aureus
C. M. catarrhalis and select viruses
D. P. aeruginosa and select fungi

Answer 1

Nonbullous impetigo in children is commonly caused by Group A Streptococcus and Staphylococcus aureus, leading to the characteristic encrusted sores typically seen around the nose and mouth.

Step-by-step explanation:

The likely causative organisms of nonbullous impetigo in a 6-year-old child include Group A Streptococcus (Streptococcus pyogenes) and Staphylococcus aureus.

Impetigo is a common skin infection among children that presents with vesicles, pustules, and eventually leads to the formation of encrusted sores, typically around the nose and mouth area. The nonbullous form of impetigo, characterized by yellowish crusts formed after the rupture of vesicles and pustules, is most commonly caused by both Group A Streptococcus and Staphylococcus aureus, individually or in co-infection.
