Unit 7 Introduction In this piece of coursework‚ there are few amounts of ideas and experiments that I could achieved of which different products to test for my concluding idea. The type of bacteria that I am going to discuss and chosen is E-coli. I will also going to research the effectiveness of antibacterial cleaning products‚ for instance sanitizer. I will also‚ research which is the most effective product for the house hold and some other work places. Background Information What are

Clostridium difficile There are many microbes that live in the human digestive tract. Most keep us regular and healthy. Some of these organisms keep others in check. When the balance of these good and bad organisms is disrupted‚ we can become sick. Clostridium difficile (C.diff or C.difficile) can grow out of control if this happens. This happens when a person is on antibiotics for another reason and the normal flora of the gut is eradicated. Clostridium difficile is typically found in hospitals

Salmonella · What is the infectious agent (pathogen) that causes this infectious disease? For example‚ the name of the bacteria‚ virus‚ or parasite. Salmonella bacterium causes the Salmonellosis‚ which is a type of food poisoning. The most common types in the US are Salmonella serotype Typhimurium and Salmonella serotype Enteritidis. · How is this infectious agent transmitted through food or water? This disease can be transmitted through food that has been contaminated

There were numerous advancements in the medical world in England throughout the 1800’s. Many things that are being used in hospitals today were developed in this time period‚ such as anesthesia‚ x-rays‚ and many other things. The Germ Theory was an important discovery for the medical field in the 19th century. Louis Pasteur proved that the souring of milk was caused by living organisms. He would boil liquids known to ferment in a “swan necked flask” and let them cool‚ he found that none of them

1. What type of foodborne illness did the individual contract? Aaron from case study #1‚ had most likely contracted the foodborne illness called Clostridium perfringens. I believe he contracted this specific foodborne pathogen because the illness is caused by improper temperature of prepared foods in meat products such as roast beef or turkey. This organism is known to cause severe diarrhea and nausea due to the bacterias being contaminated through foods. Since Aaron and his wife’s beef stew was

Introduction: Bacteria need specific living conditions to survive. The ideal conditions for bacterial growth is a warm‚ dark‚ and damp environment. This provides the maximum effectiveness for bacterial growth. The areas in our school that contain the most bacteria would be the water fountains because the bacteria from our mouths drop off on to it when we drink from it‚ and because water fountains are not regularly washed in comparison to weight equipment. Water fountains also provide a warm damp

Discussion/Conclusion: It was hypothesized that the absence of calcium‚ or the presence of the following inhibitors: colchicine‚ and neomycin; will prevent flagella regeneration in Chlamydomonas reinhardtii‚ following the deflagellar treatment of a pH shock and neutralization‚ by depicting a constant percentage of immobile cells. Prior to the lab series‚ it was expected that the positive control would present a decreasing percentage of immobile cells‚ and the negative control would present an increasing

Not all microbes are unpleasant for people they can actually serve us well.There are a number of reasons why not all microbes are bad for people. Bacteria can help the garbage to decompose‚ they are produced in medicines to help fight harmful infections and they benefit the taste of food. Microbes‚ or “microscopic organisms‚” are tiny forms of life that surround us and are too small to be seen with your eyes. To be able to see microbes we need to use a microscope. Bacteria are classified and identified

Biol 228 Virulence factors of Legionella pneumophila The Gram-negative bacterium Legionella pneumophila contains a singular monopolar flagellum which is composed of a major subunit‚ the FlaA protein. Motility is associated with the infectious phase of L. pneumophila. In the initial phase‚ the replicative phase‚ the bacteria are immotile and have nonexistent or low toxicity. The growth of flagella leads to the infectious phase‚ where the new motile form of L. pneumophila is highly toxic and

Introduction: Biological organisms are classified uniformly in order to easily categorize and identify organisms. This classification‚ or taxonomy‚ uses the genus name followed by the species name‚ in Latin. By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are
