"turbidity" poems - Hello Poetry

Preventing contamination, A constant challenge in cell culture. Contamination not only affects, The culture in question and, Costs time and money, But also endangers the reproducibility of results. No cell culture problem, Is as universal as that of culture loss Due to contamination. Generally, contamination may be separated, Into categories of microbial, And eukaryotic contamination. Examples of microbial contamination include: Bacteria (including Mycoplasma), Fungi and yeast; Eukaryotic contamination includes: Cross-contamination with other cell lines. Bacteria, yeast and fungi, The three more common types of contamination, But luckily these forms are often detectable, Under the microscope and, By visual cues, Like colour or turbidity changes in the medium. Mycoplasma is a small genus of bacteria, That lack a cell wall and for this reason, They remain unaffected by common antibiotics. They are also difficult to detect, With standard microscopes, Due to their size, about 0.1 μm in diameter, And the fact that they often attach to host cells. To prevent contamination, Use 70% ethanol for disinfecting, Equipment & surfaces, Related to cell culture. Sterile filter the media first, Before bringing to the lab. Fetal Bovine Serum, A potential source of contamination, Contains mycoplasma. Filter it at 0.1 μm, or, Gamma irradiate it. Aseptic technique, Necessary. The laboratory workers be the last, But not the least source of contamination. Teach them the ideal laboratory practices, To ensure asepticity in a laboratory.
