Biology Research Task- Lucy Kerslake What causes antibiotic resistance? Antibiotic resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other

strep throat‚ pneumonia‚ whooping cough‚ and acne. The misuse and over use of antibiotics is causing antibiotic-resistant infections or “super bugs” to surface. In 1967‚ penicillin-resistant pneumonia‚ called pneumococcus‚ surfaced in a small remote village in Papua‚ New Guinea. Around the same time‚ American military personal in southeast Asia were acquiring penicillin-resistant gonorrhea from prostitutes. Then in 1983‚ a hospital recorded an intestinal infection caused by the bacterium Enterococcus

known to be DDT was used. The genetic variation makes them resistant to the pesticides. (2) These DDT pesticides were used on the bedbug population‚ making them resistant to the pesticide. This illustrates natural selection because those resistant with the pesticide survive best. Which is heritable to their population with the resistant pesticide offspring. This give their offspring the best fitness for adaptation to survive and breed resistant pesticide to their offspring as well. (1) 2. Over the years

Topic: MRSA and You. General Purpose : To inform Specific Purpose: To inform the audience about the bacteria Methicillin-Resistant Staphylococcus Aureus. Thesis Statement: MRSA is an infection caused by a strain of Staphylococcus that has become resistant to antibiotics commonly used to treat staph infections. Preview Statement: Many of you have heard of MRSA‚ today im going to tell you exactly what type of bacteria it is and how to minimize your exposure to it. Introduction: Attention

Use this information plus information from secondary sources to answer the following questions so you will have a case study on antibiotic resistant bacteria. In this case study you will need to show how an environmental change can lead to a change in a species. Note: this will also cover content in the Search for Better Health topic. 1. Outline the purpose of anti-biotics

Examples of Genetically Modified Organisms (GMO)e’ Many of our common crops‚ such as corn‚ canola‚ potatoes‚ tomatoes‚ squash‚ and soybeans‚ are genetically modified. The majority of these crops were herbicide-resistant as well as insect-resistant‚ while the others may contain increased nutrients such as vitamins‚ produce yield earlier‚ or are able to survive weather extremes. Genetically modified tomatoes were introduced to the market in 1994‚ becoming the first commercially grown transgenic crop

All of the mechanisms of evolution were present in both simulations. Natural selection was present due to the fact that the environment was selecting for specific traits. In Addie’s case‚ the resistant bacteria was being selected for by Addie’s body. In the Mt. Laguna and UCSD birds‚ the boldness behavior was being selected for in the city. Migration leads to isolation in both simulations as well. In Addie‚ the resistance spread throughout her

Sometimes antibiotic resistant infections are called super bugs. This essay attempts to discover how it happens‚ how it can be prevented and possible treatments
