Coming Soon to a Person Near You! Understanding Microbes and Disease By: Shirley Grimsley Essential Question: How can science help us to understand the world around us? Rationale Microbes are a part of our lives every day. Some of them are good for us, some of them are harmful, and some of them are deadly. We need to understand the role microbes play in our lives and how to prevent diseases that are associated with them. Many microbes in our world cause sickness and disease in animals and plants. Some Microbes in Our World Entamoeba Protists histolytica Streptococcus Bacteria AIDS Virus Protists Entamoeba histolytica Causes dysentery, a severe form of amebiasis associated with stomach pain, bloody stools, and fever. •Plasmodium, a one-celled parasite transmitted by a mosquito. •Causes Malaria, associated with flu-like symptoms and intestinal problems. Plasmodium attacking a red blood cell Bacteria Streptococcus Bacterium Causes the strep throat, a painful sore throat and fever. Mycobacterium tuberculosis Causes Tuberculosis, a highly contagious respiratory disease. Viruses Retroviridae - HIV (Human Immunodeficiency Virus) Causes Acquired Immunodeficiency Syndrome (AIDS), which is a deadly disease that attacks the human immune system. Orthomyxoviridae – Influenza Virus Causes the flu, which is a respiratory infection that often causes the infected person to have a fever, headache, and body aches. How can you prevent the spread of diseases caused by microbes? Top 5 ways to help prevent the spread of disease: #5 - Use antibiotics correctly. #4 - Get immunized. #3 - Use care when preparing and handling food. #2 – Keep surfaces clean and disinfected. And, #1 - Wash your hands.
