Biology Discourse Community

Great Essays
A discourse community includes individuals who share common values and ideas, work to accomplish the same goals, and communicate using their own terminology. Biology is a natural science based on critical thinking and continuous research of new hypotheses, therefore effective communication is a key characteristic. The members of this discourse community are constantly sharing their ideas and new discoveries. As being part of this discourse community, communication with others using scientific language and writing is taught early on. This significant characteristic is evident in my research paper. The first principle in effective communication is language. In a biology discourse community, a scientific language is developed amongst its members. …show more content…
Bacteriophage is a virus that attacks bacterial cells and “disrupts” its normal metabolism, causing “the bacterium to lyse” (Sulakvelidze et al., 2001). Its effect on bacteria make the bacteriophage a possible new treatment for antibiotic resistant superbugs. Golkar et al. (2013) discuss the various advantages bacteriophage therapy offers over antibiotics. They are “very specific to their hosts”, meaning they can be easily manipulated to detect a specific bacterial infection. Antibiotics, on the other hand, cannot be controlled in such a way. They kill both pathogenic bacteria and normal human microorganisms as well. Another advantage is that when bacteriophage finds the infection site, it will replicate to kill all the bacteria, and it will not travel any further. Antibiotics, instead, will travel throughout the entire body, which may cause secondary infections or undesired side effects. Another advantage is that bacteriophages are “environmentally friendly and are based on natural selection”, making them identify bacteria much faster than antibiotics. Developing new antibiotics, however, is a very lengthy process and carries a big price tag. Besides these many advantages, an important question still remains: can bacteria develop resistance to bacteriophages? Golkar et al. (2013) reveal that though bacteria do have that potential, it will not become as much of a problem as antibiotics present. Like bacteria, bacteriophages can undergo mutations as well, evolving into stronger viruses. Also, phage resistance can be slowed down if infections are treated with a mixture of multiple different bacteriophages, or even in a mixture with antibiotics. With all of these advantages, bacteriophage therapy is a very “promising” solution in treating bacterial

    Should the use of antibiotics be restricted? Antibiotics are a drug that is prescribed from a doctor to a patient to provide faster fighting in a bacterial infection (2). Bacteria can grow and reproduce fast, thus creating a challenge for your immune system to be able to fight them off. Bacteria are classified as prokaryotes and can survive in extreme conditions (3). Bacteria are more commonly know as “germs” (3).…

    DNA is normally referred to as nuclear DNA, but can be found in other forms, such as plasmids (Alberte et al., 2012). Plasmids are small molecules with a circular shape (Gohlmann & Talloen, 2010). Plasmids are not necessarily vital to for survival of host bacteria but do allow the bacteria to reproduce and survive in certain environments (Alberte et al., 2012). According to Gupta (2009), some plasmids are also known to assist bacteria in becoming resistant to antibiotics given. This is due to the fact that they contain certain genes, that when expressed, make them resistant (Alberte et al., 2012).…

    Firstly, bacteria acquire their resistant genes from their plasmid. Antibiotic resistance is when a bacteria survives against antibiotics and “learns” how to, “multiply in the presence of therapeutic levels of an antibiotic.” (www.tuff.edu) The surviving bacteria multiply to form antibiotic resistant bacterias. Thus, the cycle continues. Why does this phenomenon occur in the first place? One explanation is that when bacteria are put into a hostile environment with a selective pressure, they genetically mutate to better suit the hostile environment.…

    Simply put, superbugs are bacteria that have evolved to resist certain antibiotics. Although not resistant to every antibiotic, a superbug can overcome the hurdles of regular medicine and may require the use of more expensive and dangerous antibiotics to be killed. Even more so, any of the hundreds of bacterial diseases that exist can develop a resistance to antibiotics. The cause of this resistance stems from the unnecessary use of antibiotics (i.e. using them to combat viral or fungal infections) and not consuming the necessary dosage that is prescribed.…

    When a bacterial infection attacks the body’s immune system, it is common to be prescribed a course of antibiotics. Antibiotics are designed to assist the body with fighting off invading bacteria and rid the body of the infection. However, with the increasing use of antibiotics, certain types of bacteria are becoming resistant to the medication as prescriptions become more widespread, making the drugs less effective. This selective pressure encourages the bacteria to develop a resistance to the old medication, and may even develop into a ‘super bug’. Microevolution is the frequency of allele changes within a small species group with traits that help the organism to survive.…

    (CDC) The use of genetically modified bacteria, such as Salmonella which is highly immunogenic, these bacteria can be used to promote a greater immune response against other pathogenic strains related to the original pathogen. The strain that is the subject of being injected can further be changed so that it begins to produce its own antibodies and genetic material. This material can help to gain…

    What are disease-causing bacteria and how harmful could they be? By their name, disease-causing bacteria are bacteria that cause disease. The effects that they have on the human body, or any living organism, can range from mild to severe. Fortunately, we have antibiotics to help prevent the spread of infection and protect our bodies against infectious bacterial diseases. Antibiotics, also called antimicrobial drugs, are drugs that fight off infectious disease caused by bacteria.…

    SIgA covers the mucus membrane, and it is part of the primary defenses. SIgA acts as an opsonizing factor that binds to any non-self-antigens like bacterial antigens to stimulate the immune system (Geme et al., 1994). Haemophilus influenzae type B is a good illustration of a unique subversion mechanism for sIgA. Haemophilus subverts these antibodies by releasing proteolytic degrading enzyme, which destroys sIgA (Geme et al., 1994). Thus, the former examples demonstrate some pathogens’ approach to circumvent the primary…

    Bacteria grows and reproduces inside cells of the human body. Growing and dividing, bacteria make toxins or poisons and toxins damage the cells. Symptoms include headaches, high temperature and rashes that is caused by the way the human body responds to toxins and damage create from bacteria. Once the body is infected by a virus, the genetic material of the cells are overtaken. These viruses, direct cells to produce copies of itself until it results in an increase of infection to other cells.…

    One way that antibiotic resistance occurs is through the mutation of Bacterial Cells. This occurs when the bacterial cells divide thus multiplying and causing the Bacteria to find a way to become immune to the artificial immunity of antibiotics, making the use of vaccines ineffective. The natural immune system takes quite a lot longer for your body to recover and overcome the bacterial infection. Thus resulting in immunity due to the creation of Y antibodies that become immune due to the memory B cells. However the use of artificial immunity such as Vaccines and Antibiotics do not create immunity to the attacking pathogens due to the chemicals used in these medicines attack and immediately kill the antigens instead of becoming immune to them like the natural immune system does.…
