Pathogens and Semmelweiss
  1. Pathogens
    1. Bacteria
      1. Small living cells
        1. 1/100th the size of body cells
          1. Reproduce rapidly
            1. Make you feel ill
              1. Damaging your cells
                1. Producing toxins (poisons)
              2. Viruses
                1. Not cells
                  1. 1/100th the size of a bacterium
                    1. Replicate themselves by invading your cells
                      1. Use cells machinery to produce copies
                        1. Burst and releasing new viruses
                      2. Cell damage makes you feel ill
                    2. Defense system
                      1. Platelets
                        1. Help blood clot quickly to seal wounds
                          1. Small fragments of cells
                            1. If blood contains low numbers of platelets it will clot slowly
                            2. If it gets through immune system kicks in
                            3. Immune system
                              1. White blood cells
                                1. Travel around the blood
                                  1. Patrol for microbes
                                    1. Invading a microbe
                                      1. Consuming them
                                        1. Engulf foreign cells and digest them
                                        2. Producing antibodies
                                          1. Every invading cell has unique molecules called antigens on its surface
                                            1. Starts producing proteins called antibodies when they come across a foreign antigen they lock onto and kill invading cells- specific to the type of antigen
                                              1. Produces antibodies rapidly and carries them around the body to kill similar bacteria or viruses
                                                1. If infected again the white blood cells will produce antibodies and become naturally immune to the pathogen
                                          2. Producing antitoxins
                                            1. Counteract toxins produced by invading bacteria
                                      2. Semmelweiss
                                        1. Women were dying in huge numbers after childbirth from a disease called puerperal fever
                                          1. He believed it was doctors spreading the disease as their hands were unwashed from when they treated other patients
                                            1. Doctors were made to wash their hands in an antiseptic solution and the death rate dropped by 10%
                                              1. Antiseptic solution killed the bacteria on doctors' hands. There was no proof of this so his method was dropped when he left the hospital and death rates rose again
                                                1. Nowadays we have basic hygiene, education and new drugs to control disease
