They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction. These are tiny infectious agents that are so small that even a light microscope will not detect them visibly, infecting all kinds of cells from bacteria, fungi, plants, animals and humans. Some of their common illnesses and infections include colds, influenza, chicken pox, measles, mumps, herpes, norovirus and cold sores. Fungi are simple plant like single-celled organisms, reproducing both sexually and asexually via spores. They take on various forms and can include yeast and moulds.
Bacterial infections can usually be treated with anti-biotics however some types of bacteria can form a protective spore which can make them more resistant to heat and chemicals. The requirements for optimum growth are is a temperature of 37c, water, food, time, oxygen/ no oxygen. Common illnesses caused by bacteria are Salmonella, tuberculosis, MRSA, bronchitis, ear infections and tonsillitis. Virus-tend to be smaller than bacteria and in order for the cells to reproduce they need to be in a living host. The common way of treating a virus is through immunization as anti-biotics will not be effective against viral infections.
Understanding the causes and spread of infection The differences are that bacteria are an organism which produces toxins which grow and then divide. Virus - are smaller than a cell. It can't reproduce outside the cell unlike bacteria, so they invade the cells and inject the genes into the nucleus and creates copies of itself Fungi - causes disease by absorbing nutrients, and producing toxins Bacteria, fungi and viruses are all separate entities and are completely different from each other. Parasites, however, can refer to a number of different things including bacteria, fungi and viruses. A parasite is any organism which lives inside a different organism in a symbiotic relationship in which only the parasite benefits from the symbiosis.
The infection usually begins in the throat and travels downward to reach the lungs. Then the host of the infection begins to show symptoms or signs that show that the infection is spreading. Depending on the kind of the disease, symptoms may vary. There are two different types of diseases, bacterial and viral. Bacteria cause bacterial diseases as viruses cause viral diseases.
Virus:-These are smaller than bacteria and need to be in a living host to cell reproduce, the principal way of control is immunisation, antibiotics are not affective against viral infections. The virus infection can cause things like the common cold, respiratory infections, blood born viruses. Fungus:- This is a low form of vegetable life that can cause disease such as thrush or athletes foot. Parasites:- This can also be called infestation which is the presence of a large number of parasites on a host, the parasites rely on the host for survival,, parasites are things like scabies, head lice and worms, they can be combated by washing bedding on a high temperature and a good cleaning routine. Infection:- This is an invasion by and multiplication of pathogenic, micro-organisms in a bodily part or tissue which could cause harm.
uses of infectionCauses and Spread of Infection 1.1 viruses....are a coated material that invade the cells apparatus for reproduction, Bacteria......are single celled organisms; some classify them as a separate {FOURTH} kingdom of the tree life Fungi.......are multi celled organisms that form a third kingdom of life along with the plant kingdom and the animal Parasites.....are plants or animals that derive from the metabolism of other plants or animals at the expense of the host and without providing some benefit to the host 1.2 common illnesses caused by Bacteria.....uti’s an tb Fungi.....Thrush, Athletes foot Viruses....Aids, Measles Parasites....malaria, tape worm 1.3 Infection is an invasion of cells that can cause harm. Colonisation is the invasion of cells that cause harm. 1.4 Systemic....is an infection that has gone into the blood stream. Localised infection....is in one place of your body. 1.5 poor hand hygiene can lead to the spread on infection.
A communicable infection is any disease that can be transmitted from one person to another, these infection can be caused by viruses which is a microscopic organism and cannot reproduce without a host, fungi is a skin infection, bacteria is a single celled microorganisms and can thrive in different environments from extreme cold or heat and parasites infection is contamination of one organism with another living organism that then begins to feed off or reside in the initial organism. As an employee you must ensure your own health is good and not come into work if you have flu, scabies, ringworm or viral gastroenteritis (these are a few example of infections) as these infections would pose a risk to service users and colleagues, also you must maintain your own hygiene, clean hair, nails, clothes. At all times you must maintain effective hand washing when handling and preparing food, when providing personal care to service users and if you sneeze or cough in your hands. Hand washing techniques from NHS * Wet hands with water * Apply enough soap and hand wash to cover all hand surfaces. * Rub hands palm to palm.
5) Botulism can also be contracted through an open wound. This type of botulism is wound botulism and it is one of the three main types of botulism. In food-borne botulism: Types of home-canned foods provide a perfect condition for the bacteria to grow. If botulism is not treated, it will eventually lead to respiratory problems, paralysis and death. If diagnosed early, botulism can be treated with an antitoxin.
A virus is a small piece of genetic material that has a protein coating to protect itself. A virus exists for the single purpose of reproducing. They invade and ‘hijack’ normal living cells and then multiply and produce viruses like themselves. The cells eventually die from this and this is what can make people ill. Many people get viruses from either swallowing or inhaling them, being bitten or sexual contact.
Some bacteria can fight off harmful bacteria helping to prevent illness. Viruses are a small infectious agent that replicates only the inside of living cells of other organisms. Viruses can infect all types of life forms, from animals to plants to micro organisms. Most viruses are too small to be seen with an optical microscope. Viruses can spread in many ways.
