- Which of the following is NOT true about Koch's postulates? First developed by Robert Koch, the pioneering German microbiologist In the first step, the microbe that causes a naturally occurring disease is cultured from a "wild" (non-laboratory) animal which has that disease None of the other four answers (All are true about Koch's Postulates) They represent a process for showing a causal association between a specific microbe and a disease If the same microbe from a diseased "wild" (non-laboratory) host causes the same disease in a lab animal and it can be cultured from that lab animal, this proves that the microbe is the cause of the naturally occurring disease7) Identify the most correct choice: a) The time required for a bacterial population to double is called generation time Ob) Nitrogen is required by the organisms mainly to produce ATP. c) Agar is a common food source for the bacteria. d) A colony is usually a mixture of various bacterial organisms. e) a and c(a) Describe how a microorganism may become resistant to a drug to which it was previously susceptible. (b) What can health care workers do to help prevent the development of drug resistant microbes? (c) What can you do on a personal level to help prevent the development of drug resistant microbes? 2.
- It was not until 1928 that penicillin, the first true antibiotic, was discovered by Alexander Fleming, Professor of Bacteriology at St. Mary's Hospital in London. Penicillin heralded the dawn of the antibiotic age. Before its introduction there was no effective treatment for infections such as pneumonia, gonorrhea or rheumatic fever. Hospitals were full of people with blood poisoning contracted from a cut or a scratch, and doctors could do little for them but wait and hope. 1. What is the mechanism of action of penicillin? 2. Cells treated with penicillin do not die immediately, so how this antibiotic is effective? 3. Why penicillin is most effective against Gram-positive bacteria? 4. Explain penicillin resistance mechanisms among bacteria today and the causes why they gained this resistance and making this great life-saving drug not usable anymore.Antibiotic resistance is a real threat to the human race. Unfortunately, it has not been given the kind of attention it deserves. So a lot of people are unaware of the seriousness of the situation and its consequences. You are expected to do a literature search about this burning issue and turn in a paper. I am not particular about the style you use for the paper. But I am particular about the fact that you must reference every statement you make if you are taking it from somewhere. I want you to use the ACS format to cite your reference Your paper must have an introduction. Your paper must read like an essay (headings are optional). If you use a question answer format I will not grade your paper. Please do not use the numbering or bullet format in writing the paper, the use of paragraphs is more appropriate. Please ensure that your paper is cohesive in font and writing style. In your paper please address the following issues · What are antibiotics? · What is antibiotic resistance? ·…How did Jenner, Pasteur, von Behring, Kitasato, and Metchnikoff contribute to the development of immunology? How was the ability to culture microbes important to their studies?
