Introduction Legionnaires’ Disease is a kind of common pneumonia and caused by bacteria, Legionella Pneumophila. Legionnaires’ Disease becomes more and more in recent years in Hong Kong. Background information The first outbreak of Legionnaires’ Disease happened in 1976 which found in Philadelphia in the United States and caused 34 people to die. It is an acute bacterial disease, its incubation period is 2-10 days. Thus, the most common transmission of Legionella are disseminate sprays and…

staining for identifying a Gram positive bacteria – Please explain your answer? The ideal staining for identifying a Gram positive bacteria is brown-brenn gram stain is preferred to detect the positive bacteria. 13. What is the ideal staining for identifying a Gram negative bacteria – Please explain your answer? The ideal staining for identifying a Gram negative bacteria is the brown-brenn modification is superior for the detection of the gram negative bacteria. 14. How does…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

Past: The Golgi-Apparatus was first discovered by the Italian physician, after which it was named, Camillo Golgi in the year 1897 (but only reported the discovery in 1898), and it appeared in scientific literature for the first time in 1910, but its existence was only proved later in the year 1954 with the help of electron-microscopic studies. Camillo Golgi was able to identify this organelle by using a special staining technique, which he called ‘Black Reaction’, which made it possible to…

3.3 Results and Discussion 3.3.1 Agarose Particles By microscopy observation, both ABT and CSS were activated by the Mix&GoTM solution with significant colour change on the particle surface. Seen from Figure 3-1 and 3-2, a dark green layer was formed outside the particle after treating with Mix&GoTM. By visual observation, the agarose particles turned from colourless to green, which supported the microscopy observation. The activated particles were also sent for zeta potential measurement and…

So as to guarantee conscious and safe transportation of HUM, Etihad Cargo asks for that all HUM are hermetically fixed in an internal lead or zinc box, set in a wooden coffin, to keep any harm. The coffin must be secured by a proper canvas, not to make the substance promptly obvious. Urns must be secured by padded external pack and joined by a testament from the crematorium. • Marks and marks utilized on bundles containing pine boxes must be the same as those utilized for general cargo •…

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.…

can bleed easily, this makes the cleaning of the teeth more difficult, and if it remains untreated, the inflammation affects also the jaw bone [18]. While Periodontitis is not just chronic inflammation of the gums and jawbone caused by different bacteria, but also…

B) Blackthorn (Prunus spinosa) Active components of the plant are believed to be polyphenols, including flavonoids, A-type proanthocyanidins, anthocyanins, coumarins, and phenolic acids, forming unique and diversified profiles in particular organs, among which the flowers are the least (Owczarek et al., 2017). This work is the first comprehensive phytochemical and activity study of the flower extracts of P. spinosa. (Phenolic compounds of blackthorn (Prunus spinosa L.) and influence of in…
