Bacteria is a type of Prokaryotes and RESEARCH Some Bacteria can be extremely harmful to many animals bodies including humans, these germs attack the immune systems and cause sickness and diseases, these illnesses occasionally result in death. Although not all bacteria are…
Body Bacteria Exploring the Skin’s Microbial Metropolis by Allison Maclachla, Personally I found this article very engaging yet descriptive. Especially when she explained that not all bacteria are bad for you, and then continues to state some are very helpful. For instance she touches base on Staphylococcus epidermis, and how it shields us by taking up the space that Staphylococcus aureus would otherwise conquer. It’s intriguing to now know that acne (Acne vulgaris) the most common skin bacterium, works the same way. Acne vulgaris invades certain parts of our body to hold back other harmful bacteria from penetrating specific areas.…
Exam II BIO 235 1.A. Citrobacter diversus is gram negative and is a member of the Enterobacteriacea family. This is a large group which is found in water, soil, decaying matter, and even the large intestines of humans, animals, and insects. This group of bacteria is known for being responsible for hospital acquired infections which have been named nosocomial infections. Oftentimes, they can be opportunistic infections which means they often do not cause infection in immunocompetent individuals.…
It is the most abundant bacteria in the gastrointestinal tract of humans and other mammals. “Most strains are harmless, colonizing the intestines of healthy humans and animals, where they suppress the growth of pathogenic bacterial species and synthesize appreciable amounts of vitamin K…
Crawford only sticks to speaking about how microbes are bad since they have caused diseases, famine and what not. However, readers should also know that there are more good microbes than bad. It is important to know the beneficial microbes and should not be in fear of microbes. Good microbes are in foods like cheese and yogurt along with vaccines. But Crawford has painted this image that microbes have shaped our history only because of the awful diseases its created.…
) Discuss antibiotic resistant bacteria, cause and effect. Antibiotic resistant bacteria is a big concern now a day due to the use of excessive and improper use of antibiotics. It is very common for people to star taking an antibiotic and stop the regimen as soon as the symptoms are gone. With this practice, bacteria that were not killed by the antibiotic but were exposed, are capable of becoming immune to it.…
Bacteria are single celled microbes that are found everywhere, every habitat has them and they are carried on every human and animal, some bacteria are good and some are bad. Good bacteria can help us digest food whereas bad bacteria are pathogens that make people unwell and can create unwanted symptoms (Microbiology Online, 2016). Staph bacteria can live harmlessly on the skin, 20-30%…
Experimental trials were performed by students over a timeframe of three weeks to determine the identity of three unknown bacteria contained in broth medium stored in labeled test tubes that were randomly assigned containing: one Gram positive bacterium, one Gram-negative paracolon, and one Gram-negative coliform (Carson, 2016). The unknown sample assigned in this experiment was #19. After initially streaking the solution on clean streak plates and TSA agar, the identity was determined from a Gram-stain of a single, isolated colony; this was confirmed by isolation of that pure colony and viewing the pure sample in a Gram-stain under a microscope yielding a blue colored cocci morphology with no Gram-negative contamination. This was followed by Gram-negative isolation by a Gram-stain showing a myriad of Gram-negative bacillus rods, with no presence of Gram-positive. Further tests…
As humans, we tend to think not of microbial life as significant but rather minuscule. This notion of anthropocentrism is considered, then, to be invalid. While it may not be fully understood by us as to why, bacterial life is the origins of life and this idea is supported by evolution. Moreover, bacterial life, if destroyed from all of Earth, then life would cease to exist, whereas if bacterial life were…
1. Non-pathogen name: Bacillus subtilis 2. Description of non-pathogen: B. subtilis is a mesophilic, gram-positive bacillus that is commonly found in soil, although it can also survive in plants (1). B. subtilis are facultative aerobes, using butanediol fermentation or nitrated ammonification when oxygen is unavailable (1). The bacillus is motile by using a single flagellum and commonly forms biofilms which contain several B. subtilis all traveling in the same direction (1).…
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.…
Introduction Identifying unknown bacterium is not only vital to microbiology, but also to the medical and pharmaceutical industries in order to treat disease/infection properly. Bacteria are classified and identified to distinguish among strains and to group them by criteria of interest (1). There are several different procedures that can be utilized to identify a bacterium. This includes the oxidation test, gram stain, and catalase test. The purpose of this lab report is to show the understanding of all procedures used to identify the bacterium, and explain how the given results led to the identification of the unknown bacterium.…
In the 1940s, antibiotics were widely introduced as a cure for common types of diseases. However, some microbes were able to resist the impacts of these drugs, in other words, the pathogen remained alive. In order to help resolve the crisis, antibiotics were found through screenings of soil microorganisms. However, soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment, the researchers developed methods to cultivate uncultured organisms where they originated by using specific growth factors such as iron-chelating siderophores, to help the soil grow.…
Enterobacter aerogenes belongs to the Enterobacteriaceae family and is found in both the body and natural sources. It can be found in fresh water, sewage plants, and even certain vegetables. As for the human body, it is found in the gastrointestinal tract (Enterobacter Aerogenes, 2016). This type of bacteria is most commonly acquired in hospitals or environments that are like hospitals, making it a nosocomial bacterium. Also, Enterobacter aerogenes is mainly known as an opportunistic infection meaning it rarely causes disease in a person whom embodies a healthy immune system.…
Units of the Archaea can be described as inhabitants of drastically hostile surrondings. The Eubacteria, are pervasive living agreeably in most enviornments. Every breath carries some bacterial spores, and almost every surface holds them. When it comes to the intestines, some are helpful, giving nutrients, vitamins and absorbing water in return for space. Some prokaryotes are our enemies, causing diseases and…
