Micro-organisms: Micro-organisms Micro-organisms Micro- very small Organism- a living thing. So Micro-organisms are very small living things! N.B Viruses are often classed as micro- organisms but technically they are NON-Living so call them Microbes instead! Micro- organism man Bacteria The good the bad and the ugly!: Bacteria The good the bad and the ugly! Bacteria are small living single celled organisms that can come in good (beneficial) forms and bad (pathogenic) forms that cause disease. Some different shapes of bacteria Structure of bacteria: Structure of bacteria Flagellum (Tail for movement) Cell wall Cell membrane Slimy capsule Strand of DNA CytoplasmBacteria can double in number every 20 minutes! : Bacteria can double in number every 20 minutes! The motility (movement) of some bacteria in culture.: The motility (movement) of some bacteria in culture. Pseudomonas aeruginosa How fast!During this lesson we are going to grow some of the bacteria that are found in this room on a petri dish ……. (exciting stuff huh!): During this lesson we are going to grow some of the bacteria that are found in this room on a petri dish ……. (exciting stuff huh!)Good bacteria: Good bacteria Did you know Farts are made from methane gas which is produced by the bacteria in your gut? Good bacteria: Good bacteria Bacteria help to break down faeces (poo) in sewage works.Bad bacteria in the mouth cause teeth to rot.: Bad bacteria in the mouth cause teeth to rot. Mouth bacteria Mouth bacteriumMRSA- the bacterial superbug! Methicillin Resistant Staphylococcus aureus: MRSA- the bacterial superbug! M ethicillin R esistant S taphylococcus a ureus Methicillin (an antibiotic) WON’T Work to cure this infection! Viruses: Viruses Viruses are extremely small (much smaller than bacteria) NON-LIVING microbes that need a host cell so that they can reproduce and survive. NON-LIVING because they do not fulfil all of the MRS GREN criteria. It’s not popcorn! It’s a picture of a virus! Structure of viruses: Structure of virusesHow viruses replicate inside cells: How viruses replicate inside cellsExamples of viruses: Examples of viruses A T4 bacteriophage. This infects only bacterial cells, in this case only E. coli The HIV virus. This attacks T4 lymphocytes. It is responsible for AIDS. One sneeze can transmit many cold virus particles: One sneeze can transmit many cold virus particles Bird flu virus: Bird flu virus Measles virus: Measles virus Electron microscope picture of the measles virus Boy with measlesViruses cause cold sores, warts and verucae: Viruses cause cold sores, warts and verucaeFoot and mouth disease is caused by a virus and is VERY infectious for cows: Foot and mouth disease is caused by a virus and is VERY infectious for cows To this From thisTreatment of viral infections: Treatment of viral infections Fungi: Fungi Fungi are organisms that produce spores and come in the form of moulds, yeasts, mushrooms and toadstools. They also help things to rot and breakdown which is an essential process in the cycle of life. Why did the mushroom want to go out with the toadstool? Because he was a Fungi to be with! Examples of fungi: Examples of fungi Mould growing a bread bun Yeast cells budding There can be good forms of fungus (used to make bread/beer) and bad forms (Mould, Athletes foot and thrush).Mould and fungus causes things to breakdown: Mould and fungus causes things to breakdownFungus taking over: Fungus taking overAthletes foot: Athletes footOral thrush: Oral thrush Thrush yeast cells(So a pathogen is the scientific name for a germ!): (So a pathogen is the scientific name for a germ !) A Pathogen is something that causes diseaseSome micro-organisms are VERY pathogenic and DANGEROUS: Some micro-organisms are VERY pathogenic and DANGEROUS So you have to be super careful!How well do you wash your hands?: How well do you wash your hands?
