Rickettsia‚ mycoplasma and chlamydia are three very unique bacterias. Here are a few reasons why for each bacteria. Rickettsia is an obligate intracellular gram-negative bacteria. This type of bacteria is very small and is bacilli shaped. Rickettsia causes rocky mountain spotted fever‚ rickettsia pox‚ epidemic typhus and murine typhus disease. It is found in ticks‚ lice‚ fleas‚ mites‚ chiggers and mammals. It is transmitted by a bite (vector transmission) from an infected tick‚ mite‚ flea or any

There are six types of microbes. There is Archaea‚ Bacteria‚ Fungi‚ Protista‚ Viruses and Microbial mergers. Microbes play a big part in people’s health and in the environment. Good Microbes play a big part in people’s health. They mostly play bad parts in health even though the ratio of bacteria in your body is 85% good bacteria and 15% bad bacteria. In World War 1 more people died of illnesses caused by infection than the in actual war. Bacteria multiples really fast – like once every 20 minutes

Citrate Test: Some bacteria can use citrate as a source of carbon. To test if the unknown bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface

fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The SIM test‚ which tests for sulfur reduction‚ indole production‚ and motility‚ MRVP which is a test used to distinguish

on objects whose importance we can see. For this reason bacteria seem insignificant on the surface‚ its invisibility marking its lack of precedence as a threat. This is a misconception‚ because bacteria hold enormous power. It can heal and build‚ but also cripple and kill. It can produce sustainable fuel‚ and repair cracked concrete‚ but it can also destroy our bodies with infections and disease. In the past‚ we have been subject to bacteria‚ claiming lives long before we understood how it worked

Gram negative bacteria resistant patterns are troublesome to the general public because common illnesses could suddenly become deadly. Carbapenem antibiotics are seen as a last resort. If gram-negative bacteria develop a resistance to this antibiotic‚ antibiotics could become useless in treating a super resistant strain of gram-negative bacteria. NMD-1 is one of the most resistant genes found in gram negative bacteria. If this genes is readily passed between different types of bacteria‚ widespread

Bonnie Bassler claims that bacteria although simple have complex systems that they use to communicate with each other to coordinate. This is crucial to humans because Dr. Bassler considers humans to be 90-99% bacterial. Dr. Bassler states we have about one trillion human cells but we have about 10 trillion bacterial cells that either live in or on humans. The number of bacterial genes in those cells outnumber humans by 100 times since humans only have 30‚000 genes. These bacteria share a mutualistic relationship

reasons. There are always studies available to prove any point‚ especially one where chemically doused foods are more nutritious. But then‚ like bacteria in the throes of death‚ food manufacturers mount a valiant effort in trying to convince those near-at-hand that what they say is valid. But‚ be that as it may‚ the choice is ultimately made individually. Bacteria are‚ to a great extent‚ resistant to the effects of irradiation because of their ability to repair their damaged DNA. Sometimes‚ however‚ their

donors. It has an unusual genus since it has a property of the Archea which is uncommon in the domain bacteria. Sulfate-reducing bacteria like Thermodesulfobacteria fall into more than 20 separate genera and can be classified by the types of substrates that they use. They are divided by their ability to use acetate as a source for electrons. Thermodesulfobacteria are in Group 2 of sulfate reducing bacteria because it can use acetate and some fatty acids. Thermosulfobacteria are also important

which cause disease or spoilage of beverages and food‚ but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur‚ such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS‚ which capture public attention. Control
