About the sabouraud dextrose (sab dex) dipslides (box of 10)
This slide contains Sabouraud Dextrose Agar on both sides. Sabouraud Dextrose is an acidic pH agar for the isolation of yeasts and moulds (fungi).
The acidity of this agar inhibits the growth of bacteria whilst enhancing the growth of fungi, making it easier to test for and distinguish fungi colonies.
Each dipslide features a virtually unbreakable and flexible paddle allowing for even, full surface testing.
Easy Run Off Design
Due to the design of the dipslide, fluids will drain off quickly during testing.
Each slide has a handle built into the lid that is recessed to help keep your fingers dry during testing.
One side of the slide will have a circle indicator so you know which side was used for testing which type of contaminant.
Each dipslide is dual sided to allow multiple contamination testing with one test.
Thick Reliable Agar
Each agar is thick (approx 4mm) and raised above the dipslide to allow for easy surface testing.
Types of fungi that are detected by this agar
- Microsporum audouini
- Microsporum canis
- Trichophyton mentagrophytes
- Trichophyton flavum
- Trichophyton rubrum
- Candida albicans
- Aspergillus brasiliensis
This slide will show you the general level of infection present by indicating the amount of fungal colonies within your sample.
Control testing indicates that the presence of Candida albicans shows as cream colonies and the presence of Aspergillus brasiliensis shows as white mycelium and black spores.
How to use the Sabouraud Dextrose dipslides
Step 1 : Remove slide
Carefully remove the sterile Sabouraud Dextrose dip slide from its tube ensuring that no contact is made with the agar (to avoid contamination).
Step 2 : If Surface Testing
For surface testing, press the Sabouraud Dextrose dipslide onto the surface. If needed, place a finger on the bottom of the slide (on the plastic, not the agar) to apply extra pressure.
Step 2 : If liquid testing
For liquid testing, immerse the Sabouraud Dextrose dipslide into the fluid for 10 seconds then remove and allow to drain for a few seconds.
Step 2 : If swab testing
Apply a sample of the test substance to a sterile swab and gently apply to the agars.
Step 3 : Incubate Slide
Label the tube with the included stickers then place the slide into an incubator and allow to incubate.
Step 4 : Compare results
Count the amount of colonies that have grown on the slide and compare them to the comparison chart provided.
For air sampling (to test the air for spores)
- Remove slide from container
- Being careful not to touch the agar, turn the slide upside down and place the top side of the slide (where the cap is) into the container where it will slot in.
- Leave for approx 15 - 20 minutes
- Replace the slide within the container and incubate
Extra care needs to be taken when incubating these slides as the low pH can cause the agar to caramelise if over incubated.
