Antibiotics for treatment of Toxic shock syndrome (TSS):
**Core Concept**
Toxic shock syndrome (TSS) is a life-threatening medical condition caused by bacterial toxins, typically produced by Staphylococcus aureus or Streptococcus pyogenes. The primary treatment involves antibiotics to eliminate the causative bacteria and manage the associated systemic inflammatory response syndrome.
**Why the Correct Answer is Right**
The treatment of TSS involves broad-spectrum antibiotics that effectively target both Staphylococcus aureus and Streptococcus pyogenes. beta-lactam antibiotics, such as nafcillin or cefazolin, are commonly used for Staphylococcus aureus infections, while penicillin or clindamycin is used for Streptococcus pyogenes infections. These antibiotics inhibit bacterial cell wall synthesis, ultimately leading to bacterial lysis and toxin reduction.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incomplete.
* **Option B:** This option is not a correct antibiotic choice for TSS.
* **Option C:** This option is not a correct antibiotic choice for TSS.
**Clinical Pearl / High-Yield Fact**
When treating TSS, it is essential to promptly initiate antibiotic therapy, as delay can lead to increased morbidity and mortality.
**Correct Answer: C. Cefazolin**
