[bottom: An animated graphic of a virus with a spherical structure and spikes.] DR. Microbe: Viruses are like little "copying machines" that can only reproduce within the cells of other living beings. Imagine a virus as a burglar who needs to break into a house to make a copy of himself.. Alex: And what happens if a virus enters our body?? DR. Microbe: If a virus invades our body, can make us sick. That's why it's important to wash our hands and get vaccinated to protect ourselves.. Scene 4: The Bacteria [bottom: An animated graphic of a rod-shaped or spherical bacterium.] DR. Microbe: Now, let's look at the bacteria. They are unicellular organisms that can live almost anywhere., including inside and outside our body! Sofia: Are there good and bad bacteria?? DR. Microbe: Exactly! Some bacteria help us digest food., while others can cause diseases. That's why it's important to maintain balance! Scene 5: The Mushroom [bottom: An animated graphic of a mushroom, showing spores and fungi in a garden-like environment.] DR. Microbe: Finally, mushrooms. These are organisms that can be unicellular or multicellular., and often live in damp, dark places. Alex: Where do we find them in everyday life?? DR. Microbe: Fungi can appear on rotten foods, on the skin if we do not take care of ourselves, or in the bathrooms. Some are edible and useful, like mushrooms, but others can cause health problems.
