It is not limited to any particular region of the globe, being found worldwide. As it is so commonly found in marine sediment and soil, it may be taken up by vegetables cultivated in such soil. The bacterium also colonizes the gastro-intestinal tract of many animals and fish. Clostridium botulinum is especially associated with foods such as home canned low acid foods, honey, baked potatoes, fried onions and garlic in oil mixtures. Like all bacteria, Clostridium botulinum may only grow under the right conditions.
They live on or in their host for an extended period of time. Fungi comes in many different forms, some of which we eat (such a yeast and mushrooms). Other forms include moulds. Some forms of fungi can cause serious harm to humans. 2.2 Identify Common Illnesses and Infections Caused by Bacteria, Viruses, Fungi and Parasites * Bacteria – Salmonella, E-coli, tetanus, typhoid fever, cholera * Virus – Aids, common cold, cold sores, influenza * Fungi – Athletes Foot, candidoses, ringworm * Parasites – Ticks, fleas, lungworm 2.3 Describe what is Meant by ‘Infection’ and ‘Colonisation’ Infection is the invasion of a living host’s bodily tissue by disease causing organisms that multiply in the body and cause illness.
Moulds, yeasts), as well as more familiar mushrooms. One major difference from other organisms like: plants, animals, bacteria, etc., is that fungal cells have cell walls that contain chitin. Fungi can be killed by antifungal medicine. Parasite is a plant or animal or fungi that lives on or in other organism called the host to obtain nourishment without providing any benefit to the host. Parasites may be protozoa, yeasts or multicellular organisms.
Some fungi mass together to create toadstools. They spread by releasing spores into the environment. Parasites These are microorganisms that depend on other organisms for survival. Bacteria and viruses can be parasites. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacteria Lyme disease, Tuberculosis, tetanus, MRSA, whooping cough Viruses Polio, Norovirus, common cold, flu, chicken pox Fungi Ringworm, athletes foot, oral thrush Parasites Worms, ticks, lice, mites 1.3 Describe what is meant by 'infection' and 'colonisation' Infection Infection is the invasion on bodily tissues by disease causing microorganisms Colonisation Colonisation is when an invasion of disease or bacteria populate a specific area of the body which can cause the body's immune system to break down.
Causes and spread of infection 1.1 Identify the differences between bacteria, viruses fungi and parasites Bacteria: A bacteria is a single celled organism that is essential for all life. They are either a parasite or live independently. Bacteria have three basic shapes that include spiral, coccus and bacillus. Bacteria multiply themselves by cell division. Antibiotics can usually kill them.
1.1 Identify the differences between bacteria, viruses, fungi and parasites Bacteria are microscopic living organisms, usually one-celled, that can be found anywhere. Viruses are an infective agent that typically consists of a nucleic acid molecule in a protein coat and is able to multiply within living cells. Fungus is any member of the group of eukaryotic organisms which includes both unicellular microorganisms and multicellular fungi. Parasites are an organism that lives in or on another organism and benefits by deriving nutrients at the other's expense. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacteria commonly causes strep throat, urinary tract infections, tuberculosis, etc.
For example, penicillin. Certain types of Fungi can cause illness such as Candida which is a yeast that can cause infections such as thrush. Parasities A parasite is a tiny organism that lives in or on a host for example a body which they use in order to feed. Parasites can cause severe illnesses; there are 3 main types of parasites: protozoa, helminths, and ectoparasites. 1.2 identify common illnesses and infections caused by bacteria, viruses, fungi and parasities bacteria • food poisoning • bronchitis • ear infections • throat infections e.g.
Most viruses are too small to be seen with a light microscope. Viruses can affect any living thing from animals to plants to bacteria. E.g. influenza Fungi: a fungus is a large group of organisms that include microorganisms, such as yeast and moulds. The most common (the one that most people think of when fungi are mentioned) are mushrooms, from shitake mushrooms to the death cap mushroom.
Green algae lives all over the world. It can be found in freezing cold places, or really warm places. Green algae is mostly found in fresh water such as ponds and lakes, but it can also be found in the ocean. It can be humid, rainy, or icy where it lives. Even though algae is generally in water, it also lives on soil, trees, and rocks.
In thermohaline circlulation, differences in the termperature, density, and salinity of ocean water masses cause the nutrient-rich deep ocean water to rise and mix with suface waters Along the ocean floor you will find many creatures like plants. You will find these kinds of plants like the sponge, sea urchin, and the sea anenome.these plants are all very unique! If we were to group the plants into three major groups, they would be classified as coral weed, sea weed, and various forms of kelp. Some major animals are sharks, fish, and whales. There are many individual species in each of the categories.
