Transcript of Burrito Book of Microbiology

  • Burrito Book of MicrobiologyTales of Tiny Assassins

  • What Do We Really Need To Know?

    basic characteristicshow they infect a host what diseases they causehow they can be stopped.

  • How Viruses AttackViruses and Bacteria

  • There is a HUGE difference in their sizes.Viruses are 1/10th to 1/100,000th the size of a bacterium.Bacteria are 1/10th to 1/100,000th the size of a protist

  • What is a virus?A non-living container of DNA. Not a cell Must use another organism to reproduce

    Viruses - Basic Characteristics

  • Virus Structures and Examples

  • How We Get VirusesExposure to infected bodily fluids through activities such as sexual intercourse or sharing hypodermic needles.Sneezes!


    Bites from infected animals or insects

  • Once a virus has found a new host

  • Diseases Caused By VirusMeasles, mumps, rubella, polio, encephalits, diptheria, chicken pox, small pox, mono, warts,

    and also colds, flu, HIV, yellow fever,herpes, bird flu , hepitiusA/B and many more!Polio VictimFlu epidemic of 1918viral pneumonia...

  • How do You Stop A Virus? ImmunizationsNatural antibodiesAvoid others who are infectedWash your handsMaintain a strong immune systemMonoclonal antibody

  • What are Bacteria?Different bacteria can eat everything from sunlight, to sugar to iron and sulfur, and may emit toxins as waste products. Single-celled prokaryotes with tiny flagella.They can be found everywhere and in large amounts. 100,000 / square inch of skin; 1,000,000,000 /teaspoon of dirt.

  • Sphere-shaped bacteria (cocci) sometimes grow in chains or in clumps like a bunch of grapes.Rod-shaped bacteria (bacilli) can also form in chains. Spiral-shaped bacteria (spirilla) can use their shape to propel themselves by twisting like a corkscrew.Bacteria Forms

  • Diseases Caused by BacteriaWhooping CoughLeprosyTetanusSalmonella Botulism Scarlet fever

    Ear Ache Strep throatCholeraDysentery GonorrheaAnthrax Diphtheria SyphilisTuberculosisBacterial PneumoniaTetanus LeprosyAnd dont forget Septicemia!

  • How Bacteria InvadesCoughs or sneezes!Close contact with an infected personContact with feces CutsIndirectly, by touching contaminated surfacesDrinking contaminated waterEating contaminated food without cooking it thoroughly.

  • How Prevented/Cured/MangedAntibioticsDisinfectantsClean waterCooking meat throughly


  • and Id wash carefully after wearing that meat, too

  • ProtistsStained Volvox and Amoebas

  • Basic Characteristics Of ProtistsSingle-celled eukaryotesLive in waterEveryone classifies differently

    Can live in colonies so they look big, like kelp.GiardiaKelp

  • Sickness Caused By Protists

    Pfeisteria -pfeisteria dinoflagellateMalaria - plasmodiumAmoebic dysentery -Entamoeba histolytica

    Pfeisteria dinoflagelateMost protists are benign to humans.

  • How They InfectConsumed in dirty waterMosquito bitesUncooked food

  • How to Prevent InfectionClean waterInsecticides, anti-malarial medicinesCooking food thoroughly

  • Eat decomposing organic materialLike moist areasCome in many formsMacroscopic and microscopic

    Fungi Characteristics

  • Mycelium and hyphae structure

  • Sicknesses Caused by FungiRingwormAtheletes FootYeast InfectionPoisoning

  • How fungi infectSpores carry on the wind everywhere.Atheletes Foot - direct contact with fungus on surfacesBacteria/fungal imbalance

  • How Prevented/CuredFungicidesGood hygeneAvoiding fungus-friendly surfacesDont eat wild mushrooms!

  • Whats on Tuesdays Test?All this info about small things that kill you:Viruses, bacteria, fungus, protists:What they look like, misc. important information, diseases caused by, how to prevent.

  • What Do We Need To Know About Cells?

    How to use a microscopeCell TheoryThe difference between animal and plant cells.Role and function of the cell organelles.Cell processes: photosynthesis, respiration, and mitosis/meiosis.
