What Is Phage Bacterial Infection

Improved Essays
Bacteriophages are viruses that attack bacteria with the sole purpose of replication, as phages cannot do it on their own. The phage structure consists of a capsid, a protein head that houses nucleic acids, and a tail, which allows for nucleic acid transfer during the infection of bacteria. The first step in phage bacterial infection is attachment, in which the phage tails have the role of cell surface receptor localization (Rhakuba, et al., 2010). Next, the phage injects its genetic material into the bacterial cell, which then circularizes and may follow two types of growth: lytic or lysogenic. In lytic growth, phageal DNA replicates and phage proteins are synthesized, leading to the assembly of new phages. The bacterial cell then lyses,

    The broth will turn yellow if the microorganism can utilize carbohydrates, and an air bubble will get trapped inside the Durham tube if a gas by-product is produced. All the microorganisms were able to utilize lactose, so the focus will be on their lactose gas production instead. It was observed that the Micrococcus luteus Durham tube had no gas by-product, therefore there is no lactose gas production. It was observed that the Citrobacter freundii Durham tube had a gas by-product, therefore there is lactose gas production. It was observed that the Hafnia alvei Durham tube had no gas by-product, therefore there is no lactose gas production.…

    It is generally accepted that a virophage is a viral agent that infects other larger viruses. It is a dsDNA virus which utilizes the replication factories of other viruses to reproduce itself. Virophages are essentially parasitic in nature, much in the same way as traditional satellite viruses. It is not without controversy that distinctions between satellite viruses and virophages are described. The difference between the two often seem more semantic than factual and more supported by conjecture than observation.…

    Viruses have tails that have fibres in them that attach to a specific host so the virus can only infect bacterium that the virus has a specific receptor for. Most viruses that infect animals and plants do not have tails because the virus does not spread with the virus injecting itself. The tail is the syringe, which connects the virus with the bacterial cell and injects the viral genome into the bacterial cell. In plants and animals, viruses are transmitted through plant to plant by insects or in animals, they can be carried by blood-sucking…

    To identify unknown bacteria is crucial, especially in cases where a pathogenic infection were to occur. If we were not able to identify bacteria, infections would spread uncontrollably as there would be no way to know what treatment is necessary to successfully put an end to them. The ultimate purpose of this experiment is to be able to practice identifying unknown bacteria under a series of tests, to further familiarize ourselves with the characteristics of certain bacteria and how they react.…

    Epstein - Barr virus or, Human herpesvirus 4, is the virus that causes infectious mononucleosis, and contains double-stranded DNA. This virus is species specific in that it only infects humans. The Epstein-Barr virus was discovered in 1964 when Michael Anthony Epstein and Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, they then linked the virus to the disease infectious mononucleosis. Once the host is infected with the virus it stays in the host for the remainder of the host’s lifetime, and lays dormant in the host’s immune system.…

    An article written by Eric Keen titled, Phage Therapy: Concept to Cure looks at a little history of phage therapy and it’s future outlook in medicine. This article mentions how the abuse of antibodies continue to drive bacterial resistance, and that we must seek approaches that can keep up with the bacteria they are designed to kill. The theory in this reticle is that we should use bacteriophages to combat drug resistant bacteria. Phage therapy represents a potentially significant weapon in our battle against bacterial disease. Phage therapy is extremely beneficial because it only attacks a particular strain of bacteria, giving it advantages over traditional chemotherapy.…

    B-complex which is formed by pyruvate yeast extract encourages growth. The selectivity of the medium is influenced by Lithium chloride and 1% potassium Tellurite solution which inhibits the growth of other organisms beside staphylococci. Coagulase differentiation results from the addition of potassium Tellurite and egg yolk emulsion. Staphylococci that has lectithinase breaks down the egg yolk and causes hemolysis around the colonies. After an incubation time of 24 hours the colonies appeared black, this occurred as a result of potassium Tellurite being reduced.…

    The bacteria enter a host via portals such as damaged skin, certain mucous membranes, the lungs and conjunctival membranes. They are not thought capable of penetrating undamaged skin except where it has been exposed to water and has swollen significantly. Transfer to the portal requires the bacteria to be enveloped in water and so normally involves direct contact with urine or water containing the bacteria in suspension. Entry via the lungs requires inhalation of aerosol droplets and not the bacteria alone. Leptospires cannot exist as spores or reactivate once dessicated in the natural environment.…

    A key difference between bacteria and a virus is their ability to reproduce and replicate. As bacteria are living organisms containing DNA, ribosomes, and proteins they do not need to use cells to replicate. They utilise the process of binary fission for reproduction. Unlike bacteria, a virus cannot replicate or express their genes without a host cell and must undergo a lytic/lysogenic cycle. With the lytic cycle, the virus will bind to the host cell and either inject their genes into the cell or bind to cell membrane receptors causing mediated endocytosis of the whole virus.…

    There are many fundamental differences between viruses and bacteria from their size and structure, to their biology. Bacteria are single-celled microbes that are alive, have a metabolism, are able to reproduce by binary fission, and have motility (4). Bacteria can be either harmful, causing disease and illness, or beneficial by helping to maintain life, as well as making our life more comfortable. Antibiotic are used to kill off bacteria that are harmful. Viruses are nonliving and require a host cell to carry out their activities.…
