CFU means colony-forming units. A visible colony develops from a viable microorganism or group of microorganisms capable of growing under the selected test conditions.
Why dipslide results are compared visually
Dipslide charts show representative colony densities. The developed test is compared with the nearest image or range. This produces a practical semi-quantitative estimate suitable for routine trending.
Use trends, not isolated numbers
A consistent rise across several tests is often more useful than one isolated result. Record the sampling point, temperature, process condition, cleaning activity and treatment change with each result.
Factors that affect growth
- Incubation time and temperature
- Media type
- Sample handling
- Disinfectant or biocide residual
- Organism type and physiological condition
