Microbes

Microbes Microbe- a living organism that is so small it can only be seen with a microscope 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

Bacteria Defined as: Single-celled (unicellular) organisms that have no nucleus.

Basic Characteristics Bacteria Basic Characteristics Living Unicellular Multiple shapes Some are harmful & cause disease Some are helpful & cure disease and break down decaying material

Bacteria How it gets Energy Some bacteria can make their own energy through photosynthesis Some bacteria must gain energy through eating other organisms (cellular respiration)

Spread How does this organism infect other organisms? Bacteria Contaminated foods Contaminated soil Contaminated water Contact with other organisms, etc.

Examples Treatment of Disease Strep Throat Staph Infection Bacteria Examples Strep Throat Staph Infection Food Poisoning Treatment of Disease Antibiotics Prescribed by doctors

Prevention of Disease Proper hand washing & hygiene Bacteria Prevention of Disease Proper hand washing & hygiene Proper handling of food Cover your mouth when you cough, etc. Any other?

Bacteria Different Shapes Means: Spiral Examples: Cholera

Bacteria Different Shapes Means: Corkscrew Examples: Lyme Disease

Different Shapes Bacteria Means: Spherical Examples: Strep Pneumonia Staph MRSA

Different Shapes Bacteria Means: Rod-Like Examples: E-Coli Yogurt Diphtheria Tetanus Tuberculosis Leprosy

Fungi Defined as: Any of a group of spore-producing organisms “feeding” on organic matter Examples: yeast, molds, & mushrooms

Basic Characteristics Fungi Basic Characteristics Living Unicellular or Multicellular Multiple shapes Some are harmful & cause disease Some are helpful & cure disease and break down decaying material

Energy Feed on organic matter Fungi Energy Feed on organic matter Decomposition reaction for use in cellular respiration

Spread How does this organism infect other organisms? Fungi 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

Examples Treatment of Disease Athletes Foot Ring Worm Fungi Examples Athletes Foot Ring Worm Skin, Hair, Nail, Eye, Lung Infections Yeast Infection Treatment of Disease Antifungal medications

Prevention of Disease Clean skin injuries Fungi Prevention of Disease Clean skin injuries Wear a mask and/or gloves when working in damp and dusty areas Proper hygiene

Virus Virus Defined as: Non-living substance that has to inject its genetic material into a living host cell in order to reproduce.

Basic Characteristics Virus Basic Characteristics Non-Living Unicellular Much smaller than bacteria Multiple shapes Harmful & cause disease

Virus Energy Must “use” the host cell to obtain energy

Diseases How does this organism infect other organisms? Virus A virus must infect the host cell to replicate Viruses can enter the body through ingestion, inhalation, and injection

Examples Treatment of Disease Influenza (the Flu) AIDS Common Cold Virus Examples Influenza (the Flu) AIDS Common Cold H1N1(swine flu) Chicken Pox Treatment of Disease Rest Some antiviral medications are available Prevention

Prevention of Disease Proper hygiene Proper hand washing Vaccinations Virus Prevention of Disease Proper hygiene Proper hand washing Vaccinations

Parasites Parasites Defined as: An organism that lives in or on another organism (its host) and benefits by taking nutrients from the host (harms the host)

Basic Characteristics Parasitez Basic Characteristics Living Unicellular or Multicellular Multiple shapes Harmful & cause disease

Basic Characteristics Parasites Basic Characteristics Host cell: the cells of the host organism. Much like a virus must infect the host cell to multiply

Parasites Energy Most “use” the host to obtain energy through cellular respiration Some Protists obtain energy through photosynthesis

Diseases How does this organism infect other organisms? Parasites Enters the body through contaminated food Protozoa (single celled organisms) and helminthes (flatworms, roundworms, etc.) Enters the body through vectors Fleas, ticks, mosquiotos, etc. Enters the body through contaminated soil, and water

Examples Treatment of Disease Malaria Ticks Mistletoe Tapeworms Parasites Examples Malaria Ticks Mistletoe Tapeworms Treatment of Disease Prescription medications to kill parasite and to treat the infections

Eyelash Mite (Zoomed in on one eyelash) Cat Flea (Zoomed in)

Parasites Prevention of Disease Proper hand washing and hygiene, proper filtration of water, proper handling of food, etc. Preventative medications
