1. MICROBES

2. The Virus  Genetic material + Protein coat  Geometric shapes  Non -living, Reproductive machine

3. Villains  HIV  Hepatitis  Herpes  Influenza  Smallpox  Ebola

5. Infective Pathways  Lytic Virus recognizes cell begins cycle of infection immediately. (illness begins) (influenza, common cold, ebola)  Lysogenic Virus “hides” in genetic material of host. (provirus) Infective cycle is delayed & infection is harder to treat. (HIV, hepatitis, herpes)

7. Heroes ?  Variegated leaves - flowers

8. CONTROL  Vaccines  Temperate – harmless form of a virus is injected  Live – small amts of weakened virus BOTH encourage the immune system to make antibodies.

10. Bacteria  Smallest living organism  Survive in every environment  Helpful & harmful  3 shapes, orientations

11. Spherical (Coccus)

12. Rod (Bacillus)

13. Helical (Spirillum)

14. Gram + / Gram -  Staining technique used to help identify bacterial flora  Gram + flora = peptidoglycan in cell wall (stain purple in crystal violet)  Gram – flora = no ppg, turn pink when safranin counter stain added.

15. Heroes !  Help digest food, absorb nutrients  Boost immune system

16. Beneficial species  Acidophilus  L. casei immunitas

17. Villains  E. coli 0157  Botulinum  Anthrax

18. Exposure ?  Contaminated food  Unclean hands  Animal carriers  Warfare

19. Protection ?  WASH HANDS !  Clean / inspect food  Clean, pest free living area  Vaccines  Be alert http://youtube.com/watch?v=4lmwbBzClAc&feature=related http://www.youtube.com/watch?v=tqOVYpkZ0qs

20. Treatment Alexander Fleming 1928 Penicillium notatum mold Killed bacteria in culture First Antibiotic – transformed treatment of disease and infection

22. 1.Misuse treatments for viral infections or repeatedly for bacterial infections 2.Not all bacteria are destroyed by the antibiotic 3.Stronger, resistant bacteria remain 4.More difficult to destroy the bacteria when it infects again

24. Page 468 - text Diagram, color and label the typical bacterium in your notes

25. Protists

26. Single cell critters (Protists)  Eukaryotes (true nucleus, organelles)  Base of food web  Both free living and parasitic

27. Protist Classification  Rhizopods (amoeba)  Ciliates (paramecium)  Sporozoans (malaria- Plasmodium)

28. Rhizopod Locomotion

29. Ciliate Locomotion

30. Flagellate Locomotion

31. Villains  Entameba histolytica (dysentery)  Plasmodium (malaria)

32. PARASITIC PROTISTS

33. Protist Populations

34. Microbes  Both helpful & harmful…  Many that are harmful can be treated  Avoid contaminated food, water  Vaccines when available !  Common sense
