A Case Report of Rare and Lethal Methicillin-Resistant Staphylococcus aureus (MRSA) Peritonitis in Infancy

Shishir Kumar et al. Cureus. .

Abstract

Peritoneal inflammation without a discernible intraperitoneal source is referred to as primary peritonitis. Only 2% of pediatric acute abdominal crises are diagnosed preoperatively. Association with other infections is uncommon and is often limited to hepatic and urinary pathogens. Here, we describe a case of primary peritonitis in a one-month-old child who had laparotomy and appendicectomy as per the recommended treatment plan. There were no accompanying hepatic and urinary diseases. In this instance, methicillin-resistant Staphylococcus aureus (MRSA) was the responsible bacteria. The use of linezolid, as per the culture sensitivity report of intraperitoneal pus, ensured a smooth recovery in this case.

Keywords: acute abdominal emergencies; appendicectomy; methicillin resistant staphylococcus aureus (mrsa); perforation peritonitis; primary peritonitis.
