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.
E N D
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
Bacteria • Defined as: Single-celled organisms that have no nucleus.
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)
Bacteria Spread • How does this organism infect other organisms? • Contaminated foods, contaminates soil, contaminated water, contact with other organisms, etc.
Bacteria Examples • Strep Throat • Staph Infection • Food Poisoning Treatment of Disease • Antibiotics
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: Spherical Examples: • Strep • Pneumonia • Staph • MRSA
Bacteria Different Shapes Means: Rod-Like Examples: • E-Coli • Yogurt • Diphtheria • Tetanus • Tuberculosis • Leprosy
Bacteria Different Shapes Means: Spiral Examples: • Cholera
Bacteria Different Shapes Means: Corkscrew Examples: • Lyme Disease
Fungi • Defined as: Any of a group of spore-producing organisms “feeding” on organic matter • Examples: yeast, molds, & mushrooms
Fungi Basic Characteristics • Living • Unicellular or Multicellular • Multiple shapes • Some are harmful & cause disease • Some are helpful & cure disease and break down decaying material
Fungi Energy • Feed on organic matter • Decomposition reaction for use in cellular respiration
Fungi Spread • 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 • Examples of diseases caused by fungi: • Thrush, ring worm, yeast infections, athlete’s foot, and eye, lung, skin, hair, and nail infections
Fungi Examples • Athletes Food • Ring Worm • Mold • Yeast Infection Treatment of Disease • Antifungal medications
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.
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
Virus Diseases • 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 • Examples of diseases caused by viruses: • AIDS, the common cold, the flu, herpes, chickenpox, H1N1, etc.
Virus Examples • Influenza • AIDS • Common Cold • H1N1 Treatment of Disease • Rest • Some antiviral medications are available • Prevention
Virus Prevention of Disease • Hygiene, proper hand washing • Vaccinations
Parasites Parasites • Defined as: An organism that lives in or on another organism (its host) and benefits by depriving nutrients at the host's expense.
Parasitez Basic Characteristics • Living • Unicellular or Multicellular • Multiple shapes • Harmful & cause disease
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
Parasites Diseases • How does this organism infect other organisms? • 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 food, soil, and water • Examples: fleas, ticks, tape worms, etc.
Parasites Diseases Continued… • Diseases • Giardia infections, toxoplasmosis, malaria, infections, etc.
Parasites Examples • Malaria • Ticks • Mistletoe Treatment of Disease • Prescription medications to kill parasite and to treat the infections
Parasites Prevention of Disease • Proper hand washing and hygiene, proper filtration of water, proper handling of food, etc. • Preventative medications
