Question

List the 7 groups of microorganisms that will be discussed in this class. Define: biology. One definition of microbiology is "the scientific study of organisms that are too small to be seen with the naked eye." What is wrong with this definition? Define these terms: microbe, microorganism, pathogen, disease, infectious disease, communicable disease, toxin, toxigenic. Name a communicable disease. Name an infectious disease that is not communicable. Name a non-infectious disease. Can a disease be communicable if it is not infectious? Compare and contrast prokaryotic and eukaryotic cells. Which domains in the tree of life are prokaryotic? Where do plants, animals, fungi, algae, and protozoans fall in the tree of life? Which domain in the tree of life includes viruses? What is meant by the term "eukaryotic virus?" What is meant by the term "prokaryotic virus?" Compare and contrast bacteria and archaea. Are archaea ever pathogens? How might they relate to human health? Summarize the characteristics of each of the 7 groups of microbes. Name 3 types of shellfish poisoning and describe the clinical effects of each. How do people get shellfish poisoning? What features of algae make the unlikely to be pathogens? Does the fact that almost no algae are pathogens mean they are harmless to human health? Explain. Why are virus particles usually not considered alive? Why are viruses considered alive by some biologists? Explain the following term: obligate intracellular parasite. Which types of microbes are ALWAYS an obligate intracellular parasites? Are any other groups of microbes ever intracellular parasites? A news report says hexavalent chromium is a toxin. Is that correct? Explain the meaning of the following statements: Most types of E. coli bacteria can reproduce inside the human large intestines without causing any harm, but toxigenic types of E. coli cause severe diarrhea or even more severe illnesses. People get infected with toxigenic E. coli through contaminated food or water. Can toxigenic microbes hurt people without infecting them? Can toxigenic microbes ever infect people?
