  19. How can you catch a virus? • Exchanging bodily fluids • Insects and animals • Inhalation

  20. SYMPTOMS • Low grade fever (100 – 101) • Nausea • Loss of appetite • Muscle Ache • Fatigue (WHY??) • Low WBC count

  21. 1

  22. Can you kill a virus?

  23. What happens when you catch a virus? • WBC recognize foreign invader (antigen). • T lymphocytes carry message to other WBC to create antibodies • Antibodies flock to antigen and wrap around antigen

  24. The first virus to be eradicated off the face of the earth was small pox in 1977. It was also the first virus to have a vaccine. The small pox vaccine was created by Edward Jenner. A vaccine is a preparation containing weakened or dead microbes of the kind that cause a disease, administered to stimulate the immune system to produce antibodies against that disease

  25. What is a vaccine? • It is a weakened virus or the virus without its RNA/DNA. • It causes the body to react and defend.

  26. Vaccine-induced immunityVaccine-induced immunity results after you receive a vaccine. The vaccine triggers your immune system's infection-fighting ability and memory without exposure to the actual disease-producing germs. A vaccine contains a killed or weakened form or derivative of the infectious germ. When given to a healthy person, the vaccine triggers an immune response. The vaccine makes your body think that it's being invaded by a specific organism, and your immune system goes to work to destroy the invader and prevent it from infecting you again. If you're exposed to a disease for which you've been vaccinated, the invading germs are met by antibodies that will destroy them. The immunity you develop following vaccination is similar to the immunity acquired from natural infection. Several doses of a vaccine may be needed for a full immune response. Some people fail to achieve full immunity to the first doses of a vaccine but respond to later doses. In addition, the immunity provided by some vaccines, such as tetanus and pertussis, isn't lifelong. Because the immune response may decrease over time, you may need another dose of a vaccine (booster shot) to restore or increase your immunity. Types of vaccines Vaccines are prepared in several different ways. For each type, the goal is the same — to stimulate an immune response without causing disease. Live weakened vaccines. Some vaccines, such as those for measles, mumps, and chickenpox (varicella), use live viruses that have been weakened (attenuated). This type of vaccine results in a strong antibody response, sometimes making only one dose necessary to establish lifelong immunity. Inactivated vaccines. Other vaccines use killed (inactivated) bacteria or viruses. The inactivated polio vaccine is made this way. These vaccines are generally safer than live vaccines because the disease organisms can't mutate back into a disease-causing state once they've been killed. Toxoid vaccines. Some types of bacteria cause disease by producing toxins that invade the bloodstream. Toxoid vaccines, such as those for diphtheria and tetanus, use bacterial toxin that has been rendered harmless to provide immunity to the toxin. Acellular and subunit vaccines. Acellular and subunit vaccines are made by using only part of the virus or bacteria. The hepatitis and Haemophilus influenzae type b vaccines are made this way.

  27. What are the life cycles of the virus? Lysogenic Lytic

  28. Lytic • Virus use your cell as a HOST. • New viruses are created inside your cell. • Cell explodes releasing new viruses. http://www.cat.cc.md.us/courses/bio141/lecguide/unit2/viruses/lytsum.html

  29. Lysogenic • Virus use your cell as a HOST. • DNA/RNA from virus is replicated when you replicate your DNA. • Virus reappears every so often.

  30. Are they living or nonliving? LIVING NONLIVING • Do not reproduce • Need a HOST in order to survive • No nucleus • Do not grow • Do not make energy • Contain DNA/RNA • Replicate • Made of lipids, proteins, nucleic acids • Undergo mutations

  31. Can antibiotics be used to cure an illness caused by a virus?

  32. Are there any treatments?
