In puerperial period sepsis is M/C due to..
**Core Concept**
Puerperal sepsis is a severe infection that occurs in the postpartum period, primarily affecting the reproductive organs. It is a significant cause of morbidity and mortality among women worldwide, particularly in low-resource settings. The most common pathogens responsible for puerperal sepsis are typically bacteria that are commonly found in the vaginal flora.
**Why the Correct Answer is Right**
Puerperal sepsis is most commonly caused by Group B beta-hemolytic streptococci (GBS), Escherichia coli (E. coli), and Bacteroides fragilis. These bacteria are part of the normal vaginal flora and can cause infection when the integrity of the genital tract is compromised, such as during childbirth or postpartum. The bacteria can ascend from the vagina into the uterus, causing endometritis, or spread to other parts of the reproductive tract, leading to severe sepsis.
**Why Each Wrong Option is Incorrect**
* **Option A:** While Clostridioides difficile is a common cause of antibiotic-associated diarrhea, it is not a primary cause of puerperal sepsis.
* **Option B:** Listeria monocytogenes is a rare cause of puerperal sepsis and is typically associated with outbreaks of listeriosis.
* **Option C:** Staphylococcus aureus can cause puerperal sepsis, but it is not the most common cause.
**Clinical Pearl / High-Yield Fact**
Puerperal sepsis is a medical emergency that requires prompt recognition and treatment, including antibiotics, fluid resuscitation, and surgical intervention if necessary. Early diagnosis and treatment can significantly improve outcomes and reduce mortality.
**Correct Answer:** C.
