Brucella are

  • A.Cocci
  • B.Rods
  • C.Spirochaetes
  • D.Very short rods

Answer: D

Correct answer: Very short rods

Brucella are Gram-negative organisms so short that they appear almost oval - small enough to be mistaken for cocci at first glance, which is why they are so often described as coccobacilli. They are non-motile, non-sporing and non-capsulated, and being intracellular they are typically seen within phagocytes rather than free.
