    Esblb Strain Lab Report

    In this experiment we will inoculate individual vials of nutrient broth with various organisms that are known to be resistant to multiple antibiotics. We will also inoculate various organisms that are as close to the wild type as is feasible. The vials will be allowed to incubate at 37 degrees Celsius for 24 hours. The number of bacteria in a given cultured sample is too great to be counted directly. The samples will be serially diluted by a factor of 10 in sterile saline, to be repeated 7 times. A 10 microliter aliquot from each dilution will be placed on a 5% blood agar plate or a MacConkey plate, depending on the type of organisms plated. These plates are selected because of the ease of differentiation between organisms. The original vial and all diluted aliquots will then be refrigerated to restrict growth until the plates can be processed and evaluated. The plates will be streaked in the standard format for colony count. The plates will be incubated at 37 degrees Celsius for 24 hours. The plates will then be examined for purity of culture and for colony count. The number of colonies will be counted for each dilution. The plates that have a colony count between 300 and 30 will be used to estimate the number of viable cells in that dilution. This range is chosen because small dilution errors could have a…

    Escherichia Coli And Gram-Negative Bacterium Bacillus Cereus

    Antibiotics are used for treating human infections that are caused by specific bacteria, fungi, protozoans, and other large viruses. They are generally grouped with the class of microorganisms that they inhibit. Antibiotics are used to fight off infections within the human body system by inhibiting the growth of its infectious microbes. Antibiotics have been considered one of the greatest newest innovations in medicine but there is still yet to be a perfect ideal antibiotic. In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments, gram-staining was conducted to determine the qualities of gram-positive…

    Control by Antibiotics and Antiseptics Lab Report

    The fact that each bacterial species, and even some of their respective strains, responds uniquely to a given antimicrobial makes it necessary to have methods, which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By utilizing the Kirby-Bauer method, researchers and clinicians are able to determine the susceptibility of given microorganisms to different antibiotics and antimicrobials. While antibiotics specifically target bacteria, antimicrobials cast a wide net, nonspecifically targeting microorganisms and viruses. During this lab, we tested the effects of both antimicrobials and antibiotics on different bacterial cultures. By creating different lawns of bacteria and placing on each of them disks soaked in different antibiotics and antimicrobials, we were able to observe the susceptibility of the differing bacteria to several agents. This process that we practiced is the Kirby-Bauer method. As stated before, antibiotics and antimicrobials serve differing purposes. Antibiotics are substances, usually in the form of medication, that destroy bacteria or inhibit the growth of bacteria. On the other hand, antimicrobials act in destroying or inhibiting the growth of all microorganisms. One type of antimicrobial is an antiseptic, which acts to reduce the presence of microorganisms without harming living animal tissue (El-Mayas, 2013). It is important to note that while we were able to measure the susceptibility of these agents, we cannot conclude that resistance is present because further investigations would have to be conducted to determine if the microorganism has developed a metabolic capability to withstand the agent’s mechanisms and effects (Maxwell, 2013).…

    After watching the movie, Thirteen, there is a situational argument that arises. That argument being the decision of what was the foremost factors in Tracy’s, the main actress, life that caused her to be such a defiant thirteen year old. First of all, it is obvious that Tracy’s self-esteem has dropped. So, the question is “what had such a significant key in her life to cause her pain?” The two sides of that question are that she has low self-esteem because of issues or does her self-esteem drop because she wants to fit in.…

    One of the main responsibilities of a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly treat the patients. The structure of bacteria plays a crucial role of what antibiotics works and which do not. The chemical reaction of the bacteria is also important. Most antibiotics alter or inhibit protein structure, inhibit transcription, inhibit translation, affect cell membrane structure, or alter cell-wall synthesis (1). Bacterial resistance is another pertinent medical reason for identification. The evolution of bacterial resistance has made treatment of diseases much more difficult. Therefore, it is important to know the chemistry, structure, and resistance of the pathogenic bacteria.…

    Interpersonal communication does not comeup in everyday conversation. It is not disscussed or even contemplated by most, yet it is important to everyday life and yes even your health. There are advances in technology today that would have blown your mind not only a century ago but thirty years ago as well. But with this technology has come much lower levels of faceto face communtication, causing misconceptions to arise. People in todays society needto be more educated and aware of how interpersonal communtication affects our bussiness and personal lives, mental health, and our physical health. Good socializing with others has been proven to amp intellectual function, improve memory, and make you a much happier person. Bad socializing or even a lack of it has also been proven to cause coronary problems, a lower immune-system, and depression. Communicating with others also helps shape who we are and how we percieve ourselves. Different forms of communication also shape the way others think and act around us. I believe nonverbal communtication, listening and identity and the most important forms of communication. I chose the film “Thirteen” to portray my three forms of communication because this movie is based on a family fallen on hard times, and clearly shows both good and bad communication skills.…

    Proposal Draft 2

    The use of antibiotics have effectively prolonged life expectancy and are currently one of the most commonly prescribed drugs in healthcare facilities worldwide1. Unfortunately, widespread use and misuse worldwide have led to the emergence of ‘super bugs’ and other drug-resistant bacteria2-4. Excessive and inappropriate use of antibiotics contributes to the development of bacterial resistance5-7, an increased risk of side effects, high costs and effects requiring medical attention. Inappropriate use of antibiotics often increases the cost of therapy due to antimicrobial resistance, which gives rise to another issue of budget constraints, leading to health and economic burden, where patients who are resistance to the antibiotics would have poorer clinical outcomes and bear higher cost of treatment8-12.The practitioners should be made aware of the importance of combination therapy in the treatment of certain infections so that the chance of resistance development can be ameliorated to the most possible extent. Besides that, many studies have indicated that antibiotics are among the major groups of drugs which cause adverse drug reactions (ADRs) 13. In developing countries such as Malaysia, the cost of health care is a matter of major concern.…
