  2. Helpful Terminology • Antibodies: infection fighting proteins produced by white blood cells that fight bacterial infections. • Antibiotics: medicines that help fight bacterial infections. • Immune system: body system for fighting infections.

  3. Helpful Terminology • Immunization (vaccination): specific substance containing weakened or killed pathogens given to build resistance to A given infection. • Infection: condition caused by pathogenic material in the body. • Exposure: coming into contact with A pathogenic material.

  4. Pathogens • What are they? • What can they do to you?

  5. Types Of Pathogens • Virus: A parasitic microscopic protein material (DNA or RNA) covered by an envelope of lipoprotein. Nonliving. • Bacteria: one-celled living organism. • Fungi: single and multi-celled plants. • Yeast: one celled , oval shaped fungus. • Mold: A growth of fungi.

  6. How Pathogens Enter The Body • Alimentary canal (airborne). • Parenteral openings (direct and indirect). • Vector transmission (bites and scratches from insects, animals, etc.). • Through mucous membranes. In mouth, nose, and eyes (direct and indirect). • By sexual contact (direct).

  7. Illnesses They Cause • Virus: measles, colds, mumps, influenza, polio, hepatitis A, B, C, D, E, & G, meningitis, herpes, and others. • Bacteria: food poisoning, Strep, tetanus, scarlet fever, hepatitis, whooping cough, malaria, tuberculosis, diphtheria, meningitis, etc. • Yeasts & molds: athlete’s foot, ringworm, yeast infections, meningitis & others.

  8. Conditions For Illness • A pathogen must be present. • Must be enough of it to overcome immune system. • The victim must be susceptible to the pathogen. • The pathogen must pass through the correct portal of entry.

  9. Pathogen Control • Personal protective equipment. • Good preventive practices. • Engineering controls. • Administrative processes. • Healthy lifestyle.

  10. Pathogen Control • Personal hygiene (proper hand washing is best deterrent to infectious diseases). • Heating for one minute at or above 180º F. Will kill. • A 1:10 solution of household bleach and water is A good and inexpensive disinfectant.

  11. Symptoms Of Viruses • Flu-like, fatigue, appetite loss; • Colon ulcers & inflammation; • Lung disease, anemia increase; • Jaundice; Liver problems; • Fever, acne, and joint pain.

  13. Hepatitis A, B, C, D, E, & G Viruses • Causes liver (and other) infections. • Forms cannot be identified without testing. • Acquired primarily through: • Fecal-oral route (A). • Human blood contact or other body fluids (B). • Human blood (C).

  14. Tuberculosis • Bacterial infection of respiratory system. • Bacteria usually airborne. • Transmitted by airborne mist droplets or particles. • Infectious, but treatable. • Cough usually chronic. May or may not be productive.

  15. Tuberculosis Symptoms • Fatigue, listlessness, malaise. • Fever and night sweats . • Weight loss. • Victim usually quarantined. • Very treatable, but must follow regimen.
