Worksheet at the Front Get out a blank sheet of paper 1 12-14-15 Do NOWs Lindsay Spears Core 1 2 December th 14 , 2015 Define the following words: Microbes, Diseases, Treatment Definir las siguientes palabras: Los microbios, Enfermedades, Tratamiento 3 Microbes Microbes Microbe- a microscopic organism Another word for microorganism Usually unicellular Many different shapes Carry out life functions in a wide variety of ways Live in every type of environment on Earth There are many different types of microbes, including… Bacteria Defined as: Single-celled organisms that have no nucleus. Basic Characteristics Bacteria Living Unicellular Multiple shapes Some are harmful & cause disease Some are helpful & cure disease and break down decaying material 8 How it gets Energy Bacteria Some bacteria can make their own energy through photosynthesis & Chemeosynthesis Some bacteria must gain energy through eating other organisms (cellular respiration) 9 Spread Bacteria How does this organism infect other organisms? Contaminated foods, contaminates soil, contaminated water, contact with other organisms, etc. 10 Examples Bacteria Strep Throat Staph Infection Food Poisoning Treatment of Disease Antibiotics 11 Prevention of Disease Bacteria Proper hand washing & hygiene, proper handling of food, cover your mouth when you cough, etc. Any other? 12 Bacteria Different Shapes Means: Spherical Examples: Strep Pneumonia Staph MRSA 13 Different Shapes Means: Bacteria Rod-Like Examples: E-Coli Yogurt Diphtheria Tetanus Tuberculosis Leprosy 14 Bacteria Different Shapes Means: Spiral Examples: Cholera 15 Different Shapes Means: Bacteria Corkscrew Examples: Lyme Disease 16 Fungi Defined as: Any of a group of spore-producing organisms “feeding” on organic matter Examples: yeast, molds, & mushrooms Basic Characteristics Fungi Living Unicellular or Multicellular Multiple shapes Some are harmful & cause disease Some are helpful & cure disease and break down decaying material 18 19 Energy Fungi Feed on organic matter Decomposition reaction for use in cellular respiration 20 Spread Fungi How does this organism infect other organisms? Enters the body in multiple ways: ingestion, inhalation, contaminated soil, etc. For example: Aspergillus spores are breathed in and Fungal Meningitis is injected with steroid shots 21 Examples Fungi Athletes Foot Ring Worm Mold Yeast Infection Treatment of Disease Antifungal medications 22 Prevention of Disease Fungi Clean skin injuries Wear a mask and/or gloves when working in damp and dusty areas Proper hygiene 23 Virus Defined Virus as: Non-living substance that has to inject its genetic material into a living host cell in order to reproduce. Basic Characteristics Virus Non-Living Unicellular Much smaller than bacteria Multiple shapes Harmful & cause disease 25 Energy Virus Must “use” the host cell to obtain energy 26 Diseases Virus How does this organism infect other organisms? A virus must infect the host cell to replicate Viruses can enter the body through ingestion, inhalation, and injection 27 Examples Virus Influenza AIDS Common Cold Ebola Treatment of Disease Rest Some antiviral medications are available Prevention 28 Prevention of Disease Virus Hygiene, proper hand washing Vaccinations 29 Parasites Defined Parasites as: An organism that lives in or on another organism (its host) and benefits by depriving nutrients at the host's expense. Basic Characteristics Parasites Living Unicellular or Multicellular Multiple shapes Harmful & cause disease 31 Parasites Host cell: the cells of the host organism, much like a virus must infect the host cell to multiply 32 Energy Parasites Most “use” the host to obtain energy through cellular respiration Some Protists obtain energy through photosynthesis 33 Parasites How does this organism infect other organisms? Enters the body through contaminated food, soil, and water Protozoa (single celled organisms) and helminthes (flatworms, roundworms, etc.) Enters the body through vectors Fleas, ticks, mosquiotos, etc. 34 Examples Parasites Malaria Ticks Mistletoe tapeworms Giardia infections toxoplasmosis Treatment of Disease Prescription medications to kill parasite and to treat the infections 35 Prevention of Disease Parasites Proper hand washing and hygiene, proper filtration of water, proper handling of food, etc. Preventative medications 36
