Contamination of a culture by mycoplasma is particularly troublesome because it

  • A.can be seen easily under a microscope
  • B.is invisible and often goes undetected
  • C.kills every cell within a few hours
  • D.turns the medium bright red at once

Answer: B

These very small bacteria cause no turbidity and are not visible in an ordinary microscope, yet they alter cell metabolism and behaviour. Regular specific testing is the only reliable way to find them. Many published results have been traced to undetected mycoplasma.
