Yeast [Presence] in Bronchial specimen by KOH preparation
Active
Term Description
A KOH Preparation involves treating a specimen with KOH, a strong base that can make fungi and yeast more visible by partial dissolution of tissue cells, keratin, and other material. Fungal cells are resistant due to the high content of cellular chitin. KOH prep is generally a test for fungi, most often candida yeast, but others too, such as tinea capitis and other skin or nail fungal infections, even blastomycosis, etc. However, the KOH prep is also used to diagnose infections with mites (Demodex folliculorum in rosacea-like lesions and Sarcoptes scabiei in hyperkeratotic or crusted scabies) and sometimes even nematodes (in blue neck syndrome).

Part Descriptions
LP29134-1 Yeast
Fungi are eukaryotic microorganisms which manifest as yeasts, molds or a combination. Yeasts start as individual cells that reproduce by budding. Molds, which are long filaments or hyphae, grow by apical extension. Both yeasts and molds are heterotrophic and digest their food externally by absorptive nutrition. Taxonomically, yeast are characterized by their size and shape, the presence or absence of capsules, conidiogenesis (the process of daughter cell formation), presence of sexual spores, the formation of pseudo-and true hyphae and physiologic data. Species are differentiated based on the ability to assimilate and ferment carbon sources, and to utilize nitrate as nitrogen. Some opportunistic fungal pathogens found in humans are dimorphic. They grow as mycelium in nature and reproduce as yeast in the body. One example is Candida which can quickly transform from yeast to the hyphal phase in humans; this process helps it invade host tissue. [NCBI Books:NBK8125]

LP6358-8 KOH preparation
A KOH Preparation involves treating a specimen with KOH, a strong base that can make fungi and yeast more visible by partial dissolution of tissue cells, keratin, and other material. Fungal cells are resistant due to the high content of cellular chitin. KOH prep is generally a test for fungi, most often candida yeast, but others too, such as tinea capitis and other skin or nail fingal infections, even blastomycosis, etc. However, the KOH prep is also used to diagnose infections with mites (Demodex folliculorum in rosacea-like lesions and Sarcoptes scabiei in hyperkeratotic or crusted scabies) and sometimes even nematodes (in blue neck syndrome).
