OER DESCRIPTION:

In the biomedical science laboratory, the identification of fungus is a standard microbiological technique. Often, the lactophenol cotton blue (LPCB) technique is carried out to provide a quick and easy method of staining fungi. Slides are prepared using special dyes and stains and are then observed under the light microscope. Samples of fungi can be grown in Petri dishes. Using an aseptic technique, fungal samples can be transferred onto a slide and stained with the dye.

The fungal structures are teased out using two sterile needles so that they can be viewed and identified under the microscope. Simply, a glass coverslip is placed on the slide and it is viewed wet under the microscope. The architecture of the filaments and fungal spores helps identify the type of fungus.

This is a typical microbiology technique performed in biomedical science laboratories to determine the presence of fungus in biological tissues.
