  • Essay On Biochemical Test

    Based on the dichotomous key and series of test that was used to conduct this lab project, the biochemical tests for enteric bacteria indicated that the unknown bacterium #63 being a Citrobacter freundii (218) due to commonly found in the gastrointestinal tract and known to have the ability to ferment lactose to produce acid and gas and with few exceptions a sulfur-reducing. Humans are unique species. Just like in the world they live in have different types of cities, race, and culture; The human body also have different types of normal flora and pathogenic bacteria inhabiting in different parts of the body especially the gastrointestinal tract and these organisms are referred to as enteric bacterium that are placed in the family Enterobacteriaceae. They are characterized by their ability to glucose/lactose fermenting, oxidase negative, facultative anaerobes and being a gram-negative bacilli (Tortora, Funke and Case 2010). The whole purpose of conducting the unknown lab for enteric bacteria is to apply the lab techniques I have learned and acquired, so that I can interpret those biochemical test results to identify the unknown enteric bacterium that was used for this project. The unknown bacteria used for this lab project were Pseudomonas aeruginosa, Serratia marcescens, Proteus mirabilis, Proteus vulgaris, Klebsiella pneumoniae, Enterobacter aerogenes, Escherichia coli, and Citrobacter freundii. In the world such as the medical field, biochemical test are used to diagnose…

  • Ceftazidime-Avibactam

    officer Dame Sally Davies has even made the argument that antibiotic resistant disease should be considered a "national emergency", putting it in the same category as terrorism and natural disasters. Many of us have heard of the more common "superbugs". MRSA is by far the most common one that we hear of floating around long-term care facilities and hospitals. It turns out that a relatively new bug has also come on the scene. Carbapenem-resistant Enterobacteriaceae, more commonly referred to as…

  • Importance Of Identification Of Unknown Organisms

    The properties of selective and differential media suggest that differences between the bacterial species could be used in this lab to identify these six species but their effectiveness is unknown. The efficacy of identifying a completely unidentified bacterium in a cost-sensitive manner using these test also has yet to be determined. We hypothesized that applying a combination of selective and differential media with biochemical tests would provide a presumptive identification of the first…

  • LPOS: Skinless Chicken Costs

    no LPOS (T-1) 3. Coating formulation: 2 % alginate-LPOS (T-2) 4. Coating formulation: 4 % alginate-LPOS (T-4) 5. Coating formulation: 6 % alginate-LPOS (T-6) For each segment, two fillets were used for every test day. Therefore for days 0, 4, 8, 12 and 16. Ten samples for each lot were evaluated. So the total of 60 samples were analyzed. Evolution of the microbial spoilage The effect of alginate and alginate-LPOS coating in different levels of 2, 4, and 6% over the microbial…

  • Antibiotics: The Overuse Of Antibiotic Infection

    been instantly cured by penicillin in the early twentieth century, but in the present day, the infection needed more complicated courses and managed the different kinds of drugs to be treated. The other disease, “MRSA, methicillin-resistant Staphylococcus aureus, was a type of staph that resisted the antibiotics called beta-lactams.” The infection often began with a little cut, which got infected with bacteria. Staphylococcus aureus combated the penicillin and “the most minor cuts in the skin…

    reaction the organism has. Next a sample of the mixed broth is taken and cultured on a nutrient agar plate using streak plate technique to isolate the Enterobacteriaceae and then the plate is incubated at 35C. The plate then checked after 48 hours for isolation, and then a sample is taken and checked using a gram stain method to see if the organisms have been isolated. If the colony sampled had only one type of bacteria and it is gram negative, then re-streak plate the colony on a new nutrient…

  • Klebsiella Pneumoniae Research Paper

    use of un-clean intravenous catheters can lead to bloodstream infections. Taking antibiotics over a long course of time can also increase a person's risk of getting a Klebsiella infection. Treating Klebsiella p. infections Doctors typically use antibiotics to treat K. pneumoniae infections. However, the rise of antibiotic-resistant strains of the bacteria has complicated matters. Some "superbug" strains of K. pneumoniae are resistant to most antibiotics, including carbapenems, which are…

  • Gram Negative Bacteria

    E. aerogenes is a non-spore forming organism with 1.2-3 μm in length by 0.6-1 μm in diameter and belong to the Enterobacteriaceae Family. E. aerogenes have capsule with flagella which enable them to be motile. They are facultative anaerobes which mean they are able to survive with or without the presence of oxygen. The optimum growth temperature is range from 30oC to 37oC which classify as a mesophile. It is commonly associated E. aerogenes with nosocomial infection and they are acknowledged as…

  • Enterobacter Agar Lab Report

    A bacterial smear was then made and a simple stain was created from safranin to measure isolate 6B’s cells length underneath a light microscope. The cells were found to be 2.49 μm. A standard 16S FWD and 16S REV PCR program was used to amplify the DNA strand. Gel electrophoresis was then used to determine if a band was formed. A MoBio powersoil DNA extraction kit was used for extraction, followed by a MoBio PCR clean up kit to clean the DNA strand. Gel electrophoresis was then run again to…

  • Antimicrobial Properties Of Silver Nannoparticles

    catheter-associated urinary tract infections, ventilator-associated pneumonia, and surgical site infections [1]. According to the Center for Disease Control (CDC), five to ten percent of hospitalized patients per year will acquire a healthcare associated infection. In a 2014 report, 721,800 people acquired a healthcare associated infection in 2011 and 75,000 patients died during their hospitalization [1]. It is projected that up to 7% of patients in developed and 10% in developing countries will…
