Which root corresponds to infection?

Which root corresponds to infection?

• A. AD-
• B. SEPS
• C. PY
• D. A-

Answer: (B)

SEPS- is the root that denotes infection. It appears in terms like sepsis and septic, which specifically refer to infection by pathogens and the body’s response to it. That direct link to infection makes SEPS- the best fit for the meaning asked. AD- is a directional prefix meaning toward or to, not infection. A- is a prefix meaning without or lack. PY- relates to pus (as in pyogenic, pyoderma), which is a sign or product of infection but not the term for infection itself. So the root that truly represents infection is SEPS-.
