All of the following are common causes of septic shock EXCEPT?

Septic shock is a severe and life-threatening condition that arises from the body's response to an infection, leading to systemic inflammation and subsequently, organ dysfunction. Common causes of septic shock typically stem from various pathogens, including bacteria, that can lead to overwhelming infection and immune response.

Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa are all recognized as common bacteria associated with septic shock. E. coli is often linked to urinary tract infections and abdominal infections, which can progress to sepsis. Staphylococcus aureus, particularly methicillin-resistant strains, is known for causing skin and soft tissue infections that can lead to sepsis, while Pseudomonas aeruginosa is notorious for causing infections in immunocompromised patients and is associated with higher morbidity in septic cases.

Group A beta-hemolytic Streptococcus (S. pyogenes), while it can cause serious infections such as necrotizing fasciitis and severe pharyngitis, is less commonly recognized as a primary cause of septic shock compared to the other pathogens listed. It does not typically lead to the same frequency of septic shock cases as the other three. Thus, identifying it as an exception aligns with the understanding that, while
