Gram-positive bacteria

1. What type of agar is used for the growth of these bacteria? The identification of N. meningitides, H. influenza and S. pneumonia can be done through the cytology of CSF and through the specifics of colony morphology on blood or chocolate agar. Is this agar chemically defined or complex? The agar is chemically defined 2. What type of staining technique would you use on the he sample to aid in identification of the bacteria? The staining technique used to identifying would be a latex agglutination

bioactive compounds that involved chemicals and enzymes (Heo et al., 2003; Ekanayake et al., 2008), but there are many limitations for these techniques such as complexity, chemicals toxicity and high costs (Hoe et al., 2003). Marine lactic acid bacteria (LAB) are adapted to live in the marine habitat (Kathiresan and Thiruneelakandan, 2007) they are more suitable for the fermentation of marine biomasses and conversion of its complex macromolecules to simple compounds. The use of marine LAB isolates

Discussion Collectively, the results for the biochemical tests and 16S rRNA gene sequencing suggest that the environmental isolate is of the Bacillus species and more specifically, is the bacteria Bacillus cereus. B. cereus are Gram-positive bacillus bacteria that are typically motile species, although some strains are not (BAM 2012, Bergey 1957). This organism is commonly found in soil and food; certain strains can cause foodborne illness while other strains are used as probiotics and are found

EMB separates fecal coliforms that are produced through carbohydrates that are fermentable, such as sucrose and lactose. The different fecal coliforms represent the differential factor of this test, while the selective factor selects against gram positive organisms. Lactose fermenters appear purple, pink, blue, and black colonies, while non-lactose fermenters appear clear to light orange. This occurs because Eosin Y and methylene indicators react at low pH forming the purple precipitate. On the

Oxytetracycline (OTC) is a part of the tetracycline group of antibiotics which are commonly used to help prevent bacterial infections of gram positive and gram negative bacteria in human and animal medicine, they are also used in animal feed to help promote growth. Tetracycline antibiotics are made from Streptomyces rimosus in its fermentation phase. Oxytetracyclines chemical structure can be seen in the image above. Its molecular formula is C22H24N2O9. It is a very popular antibiotic due to its

Among the bacteria, Yersinia enterocolitica deposited elemental bismuth during the exponential phase of growth [28]. The anaerobic bacterium C. acetobutylicum was found to be able to produce hexagonally shaped Bi2S3 nanostructures with the average size of 440–500 nm [16]. Nazari et al. [5] isolated a marine Gram-negative bacterial species (S. marcescens) capable to form Bi NPs with the average particle size of

This paper is about identifying the pre-hospital use of Benzylpenicillin and identifying the evidence behind its use. It will also look and compare dugs used for treating meningococcal disease and discuss the evidence for and against these drugs and see which one promotes the best recovery. Finally this paper will discuss professional, ethical and legal responsibilities of the paramedic in administering antibiotics pre-hospital for meningococcal disease. Benzylpenicillin is a broad spectrum antibiotic

specific unknown organism with a positive test showing a yellow liquid and a negative test staying red as it was in the beginning (Phenol). My results were positive for the glucose and negative for both Lactose and sucrose. The Catalase test tested for the ability of the organism to convert hydrogen peroxide to water and oxygen gas (Catalase). To test this a drop of hydrogen peroxide was placed on a slide then an isolated colony was placed in the drop, and a positive test would cause bubbles to occur

samples. We also utilized seven different disposable swabs for this exact same reason. We also used seven packages of Para-film in order to seal the plates. Lastly we made use of a freezer in order to keep our plates at the proper temperature for bacteria incubation and growth. These are all the physical materials we made use of while conducting our own experiment. For our methods, first collected all of our materials. We

In quadrants 1 and 2 how the amount and constituents of the fingerprint residue on the substrate affects the fingerprint image, is determined. In quadrant 1, excess sebum and moisture is first removed from the finger tips with the help of a clean cloth. In quadrant 2, fingertip is first wiped around the nose or forehead to create excess sebum. Quadrant 3 and 4 were used to compare the details between untreated and dusted fingerprint residues.
