Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

more than once. The differences between a virus and a bacterium are thus: * Bacteria are unicellular‚ Viruses have no cells. * Bacteria have DNA and RNA floating in cytoplasm‚ and a cell wall and membrane. Viruses have DNA or RNA enclosed in a protein coat. * Bacteria have Ribosomes‚ whereas viruses do not. * Bacterial infections are localised‚ yet viruses are systemic. As you can see‚ there are a load of differences between viruses and bacteria‚ however there are some similarities

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While

Measles Virus In the 1800’s the measles was a very dangerous disease‚ and when people who come in contact with it will die‚ if they have never been exposed to the virus before. The measles is transmitted through the air. The way that the virus is transmitted is that infected droplets are released by coughing‚ sneezing‚ and by talking. When the infected droplets that contain the measles are in the air‚ they are taken into the body through the mouth‚ nose and eyes of the potential person that

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that
