LP186074-3   MS.MALDI-TOF
Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) is a type of mass spectrometry (MS). MALDI-TOF MS consists of three primary steps: 1) mixing the sample with an organic matrix, which provides a scaffolding and also protons for the ionization process; 2) applying a laser to the matrix, which absorbs energy from the laser and releases it into the sample, which causes the sample to desorb and form singly charged ions; and 3) using a flight tube to analyze the mass of the ions, ultimately resulting in a mass spectrum in which the mass-to-charge is plotted against signal intensity. MALDI-TOF is a soft ionization technique, meaning that molecules remain relatively intact during ionization. Because of this property, MALDI-TOF can be used for protein analysis; in contrast, older MS techniques cause extensive protein fragmentation and therefore cannot be used for this purpose. One application of MALDI-TOF is in clinical microbiology; compared to traditional methods, MALDI-TOF is faster and more accurate in identifying specific microorganisms.

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] Source: Regenstrief LOINC
