The „Microbiological (CFU) measurements in theory and practice” is prepared by Henrik Skredsvik from Avidicare. The resource explains what Colony Forming Units (CFU) are, defining them as a unit of measurement in microbiology to estimate viable bacteria or fungal cells in a sample. It outlines the reasons for measuring bioburden (CFU), such as to check installations, establish hygiene levels, and trace infections. The presentation details three primary methods for measuring CFU: passive, active, and contact sampling. It also provides useful knowledge for working in an operating room, including patient safety protocols and advice on how to correctly handle and prepare agar plates. The document concludes by listing relevant regulatory standards and offering personal takeaways and suggestions for further reading.
