Stress Test

Stress Test. The slower the pictures move, the better your ability of handling stress. Alleged criminals that were tested see them spinning around madly; however, senior citizens and small children see them standing still. None of these images are animated - they are perfectly static.

  1. Stress Test The slower the pictures move, the better your ability of handling stress. Alleged criminals that were tested see them spinning around madly; however, senior citizens and small children see them standing still. None of these images are animated - they are perfectly static.

  2. Intro to Microbiology Microbiology 2314

  3. Microbes in our Lives • Microorganisms are Small • Assist in Maintaining an Ecological Balance • Normal Microbiota Exist in Organisms • Important in Food Production • Important in Chemical Production • Can Serve as Pathogens

  4. Types of Microbiology / Bacteriology

  5. Bacilli Bacteria

  6. Shapes and Arrangements of Bacteria

  7. Mycology

  8. Parasitology / Parasitic Protozoa and Helminths Hookworm and Whipworm Eggs

  9. Amoeba

  10. New Studies • AIDS • Action of Interferons • Development of Vaccines • Healing Ability of Phages • EIDs • Biological Terrorism

  11. Renewed Interest since 9-11 in combating Biological Bio-terrorism

  12. New Techniques • Molecular Biology • Electron Microscopy • Recombinant DNA Technology • Stem Cell Research

  13. Diversity of Microbes / Bacteria • Unicellular • Prokaryotic • Shapes • Cell Wall of Peptidoglycan • Binary Fission • Flagella • Varied Nutrition

  14. Binary Fission of Bacillus

  15. Gram - Bacilli and Gram + Cocci

  16. Fungi • Mushrooms, Molds, Yeasts • Eukaryotic • Usually Multicellular with Yeasts being Unicellular • Decomposers • Organic Absorption

  17. Protozoa • Unicellular • Eukaryotic • Classified by Locomotion • Nutrition is by Absorption and Ingestion

  18. Paramecium

  19. Amoeba

  20. Algae • Unicellular or Multicellular • Photosynthesis • Producers

  21. Kelp Forrest Kelp is a Type of Algae

  22. Viruses • Noncellular • Parasites • Nucleic Acid Core • Protein Coat • Envelope • Nonliving

  23. Multicellular Parasites / Helminthes Flatworms and Roundworms

  24. Microbes and Human Welfare

  25. Decomposition of Organic Matter

  26. Bioremediation of Toxic Wastes

  27. Biological Controls In quarantine tests, potential biological pests are confined in small cages containing test plants sprayed with different microbiological control agents.

  28. Biotechnology The application of biological knowledge and techniques to develop products A potential product from guano microorganisms is an enzyme called chitinase, a protein capable of converting the chitin exoskeleton of insects and crustaceans to simpler sugars. This, in turn, may be used for alcohol fuel production. Another potential use for chitinase producing microorganisms is the biological control of insect and nematode pests.

  29. Genetic Engineering / Gene Therapy Using bacteria of genus Clostridium to selectively penetrate cancer tumors and deliver gene therapy to shrink an kill the tumors. In gene therapy, viruses are used to carry replacements for defective or missing genes into human cells Chest Tumor

  30. Microbes and Human Disease • Normal Microbiota or Flora • Pathogenicity and Susceptibility • Infectious Diseases Invade Hosts • EIDs are Increasing

  31. Why Do We Study Microorganisms? • We study microbiology because bacteria, viruses and fungi are the leading cause of death in the history of mankind. • Bacteria, viruses and fungi have been responsible for the downfall of governments, famine, and death on an almost incalculable scale. • It has only been in the last one hundred years that we have finally begun to win the age old battle with these small and deadly bugs.

  32. Why Do We Study Microorganisms? • SomeMicroorganisms Benefit Man: - Many microorganisms are involved in the production of food or are directly edible. - The presence of bacteria (normal flora) in our bodies inhibits the growth of potentially pathogenic bacteria helping to keep us healthy..

  33. Why Do We Study Microorganisms? • SomeMicroorganisms Benefit Man: - Modern biotechnology is often associated with the use of genetically altered microorganisms such as E. coli or yeast for the production of substances like synthetic insulin or antibiotics. - Biotechnological advances in agriculture also require the help of microorganisms to form Transgenic Plant with increased yield, reduced vulnerability to environmental and pathogenic stresses, and improved taste.

  34. Why Do We Study Microorganisms? • SomeMicroorganisms Benefit Man: - Microbes are involved in cycling vital elements such as carbon and nitrogen, breaking down wastes and dead organisms into simpler substances plants can use in photosynthesis. Other species are at the base of the food chain, especially in aquatic ecosystems. Even pathogens have a role in controlling the populations of their host species. Microbes are even used to digest oil from oil spills.
