to be worn by health professionals during surgery and during nursing to catch the bacteria shed in liquid droplets and aerosols…

yeasts, and bacteria which factor grapes' physical and biochemical characteristics. Some species depend on the grape ripening stage and on the availability of nutrients like yeasts and lactic bacteria, while others are only found inside the grapes, such as parasitic fungi and environmental bacteria (Barata et al. 2012). Similar to other plants grapes also have to deal with the two major microbial, fungi and bacteria. These microorganisms play a major role in grape's ecology. Fungi and bacteria…

General Information Klebsiella Pneumoniae is a "Super-bug". "Super-bug" is a term used to describe strains of bacteria that have become resistant to the majority of antibiotics that the medical community prescribes today. These superbugs can cause a range of diseases, depending on which part of the body they infect. Klebsiella pneumoniae is a bacteria which is found inside human intestines, where under normal conditions it is not known to cause disease. However, Klebsiella pneumoniae has…

tests to identify unknown microorganisms in a sample (111). Our goal in this laboratory was to perform the types of testing microbiologist do every day to isolate and identify unknown bacteria in a mixture sample. Also, throughout the project learn about the morphological and physiological characteristics of the bacteria that distinguish them from each other. The methods and testing procedures performed included: T-streak, Gram Stain, Oxidase Test, Catalase Test, and EnteroPluri-Test .…

conducting research in a microbiology lab at the Medical Faculty of Kyoto University in Japan. He succeed in culturing a strain of lactic acid bacteria beneficial to human health. This bacterium was named "Lactobacillus casei Shirota strain. It took Dr. Shirota another 5 years of research to find the right food medium for the Lactobacillus casei Shirota bacteria. In 1935 the first bottle of Yakult, a fermented milk-based drink, was produced in glass bottles. The nurses that worked for Dr.…

and identify two unknown microbes from a mixed culture. Kathryn Bart define a mixed culture as "one that contains more than one type of organism growing in a sterile medium, such as agar. The mixed culture can include multiple species of viruses, bacteria and parasites, which may or may not live in harmony with one another, sharing the available resources" (Kathryn Barr, 2016). I took number five test tube from the different microbes that I had the option of choosing from. From that I created a…

staining is a technique where certain stains are used to identify bacteria. It was discovered in 1884 by Hans Christian Gram where he used stains to differentiate bacterial cells in diseased lung tissue. Gram staining has evolved over time to become a trusted and common diagnostic tool used in clinical and research settings. Gram stains are mainly used to identify unknown bacteria. It is often the first test used on an unknown sample of bacteria. For medicinal uses gram staining is commonly used…

It does that through (PBPs) that prevent penicillin-binding proteins from joining muramyl-pentapeptide precursor site D-alanyl-Dalanine, so its stronger than penicillin (Dancer, 2001). In these antibiotics resistance happened through the nature of bacteria, which have chromosomally mediated β-lactamase able or skilled to destroy the structure of lactam ring and through plasmid transferred β-lactamases (Dancer, 2001). Cephalosporins (cefotaxime) third generation counter resistance from…

Introduction: Prokaryotic cells are cells that do not have membrane bound organelles, such as ribosomes and include organisms such as bacteria. In contrast, eukaryotic cells contains organelles and are often more complex organisms (Karp, 2010). These cells have some similar features such as the plasma membrane and the use of ribosomes to make proteins. However, there are also significant differences between prokaryotic and eukaryotic organisms. Whilst the prokaryotic/ eukaryotic…

limbs. Cellulitis is caused by bacteria. The two most common bacteria that causes cellulitis are streptococci and staphylococci and normally found on the surface of the surface of the skin. The bacteria causing cellulitis has to have a route of entering into the skin which is normally caused by a break in the skin such as an ulcer, a burn, a bite, a graze to the skin, a cut and sometimes skin conditions such as eczema, athlete's foot or psoriasis. However, bacteria may also enter the body…
