  1. BIOL 4014 Microbiology Fall 2008 Mon & Wed, Lecture 8 am – 9:40 am, LSW 444; Lab 9:00-10:50 am or 2:00-3:50 pm, LSW 546Instructor: Dr. David F. Gilmore Office: LSE 418 Phone 972-3263 Email: dgilmore@astate.edu Web: http://www.clt.astate.edu/dgilmore Office hours: TBA other times by appt. or just drop by.Lab text: Microbiology Laboratory Theory and Application 2nd ed by Leboffe and Pierce. Required

  2. Integrated Lab/Lecture course • Match up of lecture topics and Lab exercises • Additional time for discussion of lecture material, lecture exams. • Avoid “is this lab or lecture?” thinking. • Except for Lab Final, exams cover lecture and lab. • Powerpoint lectures • Each slide numbered for your reference • Listen to ME, take smart notes • Powerpoints will be posted before class, but attendance is expected! • No textbook, but online reading assignments! • Stuff • Schedules may change, more likely in lab • Alteration in points for Lab assignments • Don’t be a stranger. • Please no cell phone use or ringing in class.

  3. Grading • Four regular exams, 100 points each • Final (fifth) Exam, 100 points. • Attendance in lecture: 50 points. • Lab assignments totaling 450 points, typically • 3 or 4 Lab Reports • One Lab Final • One Unknown identification • Total 1000 points Student email for official commuication my web page: study guides, lab report directions, etc. Cheating Full syllabus is posted online

  4. Microbiology: Definitions • Microbiology: study of living things too small to be seen w/o a microscope. • What’s life? • Highly organized, self replicating, self-adjusting, capable of evolving, can obtain energy • Made of cells, comes from pre-existing cells • Are all microbes that small? • Epulopiscium and Thiomargarita: visibly large bacteria

  5. Classification of Microbes • Three domains • Eubacteria: prokaryotic cell structure • Archaebacteria: prokaryotes, but different • Eukaryotes: 4 kingdoms • Plants, animals, fungi, and protists. • What are microbiologists interested in? • Eubacteria and archaebacteria for sure. • Eukaryotes like fungi and protists • Animals (parasitic worms) but not really plants. • What’s missing? • VIRUSES!

  6. Divisions of Microbiology • By critter type: • Bacteriology, virology, mycology • Parasitology (includes protozoa, fungi, worms) • Other divisions: • Pathogenic microbiology, Immunology, molecular biology, microbial ecology • Applied microbiology: water treatment, natural products, food microbiology, environmental microbiology

  7. History: Ancient knowledge • Recognition of Immunity: • Variolation and protection from infection • Intentional contact with minor form of smallpox • Protected against Variola major • Edward Jenner and cowpox (1796) • Milkmaids catch cowpox, seem to be immune to smallpox. • Contagion: disease can be spread by contact. • Exclusion of lepers; burning of plague victims • Catapulting of disease victims into castles during siege

  8. Satire on Jenner and vaccination encarta.msn.com/.../ Vaccination_with_Cowpox.html

  9. History continued • Microbiology as a biological science • Robert Hooke, 1665, discovery of cells • Antony van Leeuwenhoek, father of microbiology • Dutch amateur lens grinder • First person to see microbes, late 1600s • Mid 1800s, microbes taken more seriously and studied using the scientific method micro.magnet.fsu.edu/.../ introduction.html

  10. History: the Golden Age • From about 1850 to start of 20th century • Read about significant individuals of this era: • Louis Pasteur • Robert Koch • Ignaz Semmelweis • Joseph Lister • Paul Ehrlich • Major concepts • Fermentation, other chemical processes due to life • Germ theory of disease: sicknesses caused by microbes • Aseptic technique; avoid infection, contamination

  11. 20th Century Microbiology • Molecular biology • Use of microbes as model systems for study • Study of DNA, proteins synthesis • Tools and processes for recombinant DNA • Applied microbiology • Food industry • Water and sewage treatment • Bioremediation • Medicine • Emerging diseases; antibiotic resistance

  12. Why Study Microbes? • Major impact on health • Responsible for disease in humans, animals, plants • Major impact on environment • Major decomposers • Nutrient cycling, elemental cycling • Microbes are talented • Live under extreme conditions • Protect against disease • Eat oil, toxic waste (bioremediation) • Make plastic • Spoil food, make food • Use light, produce light
