Presentación de los Microorganisms

  1. 1. INTRODUCTION ● We know that the microorganisms are livings things, but... What are they? They are harmful or usefull? What they produce? We are going to know about the really world of the microorganisms.
  2. 2. Microorganisms ● Microorganisms are unicellular or multicellar organisms, that are microscopic. The study of the microorganisms is called microbiology. There are microorganisms: - Bacteria. - Archaea. - Plakton.
  3. 3. What is a microbe? They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs lived in the earth.
  4. 4. Bacteria ● Bacteria constitute a large domain or kingdom of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most habitats on the planet. Bacteria inhabit soil, water, acidic hot springs, radioactive wasteand the deep portions of Earth's crust. Bacteria also live in plants, animals.
  5. 5. Microorganisms Humans have been using microorganisms for thousands of years to make products they need and enjoy, for example they use fungi to make cheese, yeast for bread, Lactobacillus bulgaricus for the yogur, etc...
  6. 6. Where they live? Microorganisms have inhabited the earth longer than any other being. They were developed when the Earth was a mass of lava, boiling water, methane, ammonia and other gases. But now, are in all places. They around us, in the air, the water... They are into our bodies too, and in our hands, and parts of our body.
  7. 7. Viruses ● A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria andarchaea. So, when we are sick, is because a harmful microorganims is into our body. But, what can we do?
  8. 8. Antibiotics Since the first antibiotic was discovered in 1928, many more have been developed and used to treat bacterial infections. Some bacteria have mutated and become resistant to antibiotics, but new drugs are constantly being developed and tested. The first antibiotic, penicillin, was discovered by Alexander Fleming in 1928.
  9. 9. Alexander Fleming ● Sir Alexander Fleming was a Scottish biologist, pharmacologist and botanist. He wrote many articles on bacteriology, immunology, and chemotherapy. His best-known discoveries are the enzyme lysozyme in 1923 and the antibiotic substance penicillin from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945.
  10. 10. Some examples of useful microorganisms ● Lactic acid bacteria. ● Photosynthetic bacteria. ● Ferrmenting fungi. ● Yeasts. ● Rhizobium. ● Penicillin.
  11. 11. Yeast ● ● Yeasts are eukaryotic microorganisms classified in the kingdom Fungi, with 1,500 species currently described.Yeasts are unicellular. Yeasts, like all fungi, may have asexual and sexual reproductive cycles. The most common mode of vegetative growth in yeast is asexual reproduction by budding. We can do some diferents aliments or drinks with the yeast: Beer, Bread, Nutritional supplements, wine...
  12. 12. Some examples of harmful microorganisms ● Escherichia Coll. ● Mycobacterium Tuberculosis. ● Streptococcus mutans. ● Salmonella enterica. ● Chiamydophila pneumonlae.
  13. 13. Chlamydophila pneumoniae ● Chlamydophila pneumoniae is a species of Chlamydophila bacteria that infects humans and is a major cause of pneumonia. . In addition to its role in pneumonia, there is evidence associating C. pneumoniae with atherosclerosis, Alzheimer's disease and with asthma. The full genome sequence for C. pneumoniae was published in 1999. C. n. This atypical bacterium commonly causes pharyngitis, bronchitis and atypical pneumonia mainly in elderly and debilitated patients but in healthy adults also.
  14. 14. Some Diseases and Infections Caused by Microbes ● Athlete's foot ● Chickenpox ● Common cold ● Diarrheal diseases ● Genital Hernes ● Malaria ● Tuberculosis ● Vaginal Infections
  15. 15. Tuberculosis ● Tuberculosis is a contagious bacterial infection that mainly involves the lungs, but may spread to other organs. The most important species of bacteria causing tuberculosis and representative is Mycrobacterium tuberculosis or Koch bacilius. The classic symptoms of tuberculosis are a chronic cough with blood-tinged sputum, fever, night sweats and weight loss.
