Question

Which disease is caused by exfoliatin toxin and is characterized by the presence of bug in the bullae? Which disease is sterile?

1) Impetigo and Scalded Skin Syndrome
2) Toxic Shock Syndrome and Staphylococcal Scalded Skin Syndrome
3) Toxic Shock Syndrome and Impetigo
4) Staphylococcal Scalded Skin Syndrome and Impetigo

Answer 1

The disease caused by exfoliatin toxin and characterized by the presence of bug in the bullae is Staphylococcal Scalded Skin Syndrome (SSSS). Impetigo is a skin infection that can also have bullae as one of its clinical manifestations.

Step-by-step explanation:

The disease caused by exfoliatin toxin and is characterized by the presence of bug in the bullae is Staphylococcal Scalded Skin Syndrome (SSSS). It is a superficial infection caused by Staphylococcus aureus, commonly seen in infants and young children. The toxin produced by the bacteria causes erythema (redness of the skin) and severe peeling, resembling scalded skin.

On the other hand, Impetigo is a skin infection characterized by the formation of vesicles, pustules, and bullae. It can be caused by S. aureus, S. pyogenes, or a combination of both. Bullae are large, fluid-filled blisters present in impetigo.

Therefore, the correct answer is option 4) Staphylococcal Scalded Skin Syndrome and Impetigo. SSSS is caused by exfoliatin toxin and has the presence of bug in the bullae, while impetigo can have bullae as one of its clinical manifestations.
