Asepsis

absence of disease-causing microorganisms

Bacteria are used to test the effectiveness of disinfectants and antibiotics. Therefore, it is important that bacteria are not contaminated with other microorganisms. To prevent contamination, aseptic techniques are used. These include:

  • Sterilising all Petri dishes and culture media using an autoclave
  • Sterilising all inoculation loops by passing them through a flame or dipping them into alcohol
