Full Specification TextEdit

g) Some medicines, including painkillers, help to relieve the symptoms of infectious disease, but do not kill
the pathogens.

m) Uncontaminated cultures of microorganisms are required for investigating the action of disinfectants
and antibiotics.
For this:
■ Petri dishes and culture media must be sterilised before use to kill unwanted microorganisms
■ inoculating loops used to transfer microorganisms to the media must be sterilised by passing them through a flame
■ the lid of the Petri dish should be secured with adhesive tape to prevent microorganisms from the air contaminating the culture.
n) In school and college laboratories, cultures should be incubated at a maximum temperature of 25°C, which greatly reduces the likelihood of growth of pathogens that might be harmful to humans.
o) In industrial conditions higher temperatures can produce more rapid growth.
