In the operating room (OR), key contributors to microbial contamination include inadequate microbial sterilization, airflow ...

The purpose of this practical is to investigate the effect of antiseptics or antibiotics on bacterial growth using agar plates and measuring zones of inhibition. This allows the selected bacteria ...

Fungal contamination of cereal grains poses a ... strands that invade host plants' tissues after spores germinate. On agar plates, the growth of mycelia for both fungi was successfully inhibited.

It is therefore important that any petri dish or agar used is sterilised before use, and that aseptic techniques are used to inoculate the plates. An inoculating loop can be used to transfer bacteria.
