Which one of these has a Chinese letter arrangement?

  • A.Clostridium tetani
  • B.Mycobacterium tuberculosis
  • C.Bacillus anthracis
  • D.Corynebacterium diphtheriae

Answer: D

Correct answer: Corynebacterium diphtheriae

Corynebacterium diphtheriae divides by snapping fission: the cells bend sharply apart but stay joined at one end, giving the V and L shapes described as a Chinese-letter or palisade arrangement. It is a useful diagnostic clue in a stained smear.
