Which root means 'bacteria'?

• A. Bacteri/o
• B. Genit/o
• C. Vesicul/o
• D. Crypt/o

Answer: (A)

Understanding medical word parts: the form that denotes bacteria is bacteri/o. This combining form appears in terms like bacteriology (study of bacteria), bacteremia (bacteria in the blood), and bacteriuria (bacteria in urine). The other roots point to different concepts: genit/o refers to the genitals, vesicul/o to a vesicle or seminal vesicles, and crypt/o to something hidden. So bacteri/o is the one that specifically means bacteria.
