report is worth 100 points towards your final lab grade. Each Q is worth 2 points unless otherwise noted. Also‚ per the Honor Code‚ this work must be your own. This is due Mon. 10/8 at 11:59 PM. The theme of this lab is the identification of unknown bacteria and viruses in a lab.

Mucositis (in vitro studies) Defention: One of the most debilitating side effects of radiotherapy and chemotherapy treatment. It is characterized by both inflammation and cell loss in the epithelial barrier. Mucositis is a very complex condition: it develops as a series of dynamic interactions that begin in the epithelium but in a later stage involves other tissue mucosal components like the endothelium‚ extracellular matrix and connective tissue. It is a frequent reason to postpone chemotherapy

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 to distinguish one organism from another and to group similar

be based on three articles that were assigned: Lipopolysaccharide modification in Gram-negative bacteria during chronic infection‚ Fortifying the barrier: the impact of lipid A remodelling on bacterial pathogenesis‚ and Pathogenicity of Yersinia pestis synthesis of 1-dephosphorylated lipid A. It will be a summary and my opinion of each article. The first article has to do with Gram-negative bacteria lipopolysaccharide layer(LPS) and how it plays a key role in host-pathogen interactions in the immune

of UV light. The test was a quantitative test to effectively the rate at which changes happen at the distinctive length of UV introduction. As the exposure time of UV light increased‚ the red-pigmented bacteria colonies turned white due to mutation.Therefore‚ both growth and mutation in the bacteria are negatively affected by increasing exposure of UV light. Consequently‚ both development and

Unit ICO2 Causes and spread of infection Assessment Criteria Outcome 1 Understand the causes of infection The learner can: 1. Identify the differences between bacteria‚ viruses‚ fungi and parasites? Bacteria : Bacteria are one cell structures that multiply rapidly and can become a colony of 2 million within 2 hours. Viruses : Visible can only be seen with an electron microscope they can float in the air‚ sit on a door handle or remain non-living. They become active when they are allowed

its an infection of a hair follicle. This infection is caused by a bacteria called streptococcus aureas. Bacterias are all around is‚ the body needs normal bacteria to function properly. Hair follicles that have been opened‚ either from scratching allow bacteria to penetrate. Upon penetration‚ the area becomes red and tender‚ over time it hardens and forms a yellow point. Mostly its pea sized. This yellow point consists of bacteria fighting white blood cells‚ which the body releases to counter

each treated? A bacteria is a living cell organism that can survive inside our body and other non living objects as well. There are both good and bad bacterias and the good bacteria is known to helps fight against the bad bacteria that makes it’s way into our bodies. According to a www.righthealth.com‚ less then 1% of bacteria is actually harmful to us. In fact‚ we couldn’t survive without bacteria in our body. A bacteria infection is described as an imbalance of bacteria that can cause harm

given to the pneumonia-like illness caused by legionella bacteria. This includes the most serious legionnaires’ disease‚ as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires’ disease is a potentially fatal form of pneumonia and everyone is susceptible to infection”. (http://www.hse.gov.uk/legionnaires/what-is.htm 11) The disease is usually contracted by a person inhaling the legionella bacteria deep into the lowest part of the lungs. The bacterial

Bacteria Bacteria are microscopic organisms whose single cells have neither a membrane-enclosed nucleus nor other membrane-enclosed organelles like mitochondria and chloroplasts. Another group of microbes‚ the archaea‚ meet these criteria but are very different from the bacteria in other ways. In fact‚ there is considerable evidence that you are more closely related to the archaea than they are to the bacteria! Bacteria are living things that are neither plants nor animals‚ but belong to a group
