Counting of viable fungal spores and yeasts can be performed from a variety of samples including air, surfaces, bulk material, etc. Different culture media and growth temperatures are used in order to reveal the diversity of the fungal content. Isolated colonies are enumerated and identified generally to the genus level using microscopy. Results are expressed as colony forming units (CFU) of a given morphotype per m3 of air, gram of bulk material, etc. Isolates can be further accurately identified at an extra cost using notably MALDI-TOF MS or DNA sequencing.
The cost (see price list) includes isolation, plating and counting.
