Which pathogens are commonly implicated in sepsis?

• A. Escherichia coli, Streptococcus A and B, Staphylococcus aureus, and other Gram-negative bacteria
• B. Streptococcus pneumoniae only
• C. Listeria monocytogenes exclusively
• D. Fungal pathogens only

Answer: (A)

Sepsis is most often triggered by a broad range of bacteria that enter the bloodstream, involving both Gram-negative and Gram-positive organisms. Escherichia coli and other Gram-negative bacteria are frequent culprits because they come from the gut and can spread during various infections. Staphylococcus aureus and streptococci, including group A and group B, are also common due to their roles in skin, soft tissue, respiratory, and invasive infections. While Listeria monocytogenes or fungal pathogens can cause sepsis in certain high-risk groups, they are less common overall. So a broad set that includes E. coli, Staph aureus, Streptococcus species, and other Gram-negative bacteria best reflects the typical pathogens seen in sepsis.
