This is in contrast to a local infection which only affects the area where the infection entered. Localised infections means it develops only in one place on the body while systemic infections spread throughout the body by the bloodstream. Poor practice that may lead to the spread of infection • Not washing your hands, not wearing gloves and aprons, not storing
Causes and spread of infections 1 Understanding the cause of infection Bacteria can be both beneficial and pathogenic. These single cell micro-organisms are tiny living beings, neither plant or animal, that normally exist together in millions and reproduce only asexually. Some of their common illnesses and infections include ear infections, food poisoning, urinary tract infections, diphtheria, bacterial meningitis, gastritis and sinusitis. Viruses differ from bacteria, being coated genetic material and in that they do not reproduce on food, needing a living host to do so. They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction.
HIPPA has found a way to ensure the confidentially of the all people with medical conditions especially those that are suffering with the ever contagious HIV/AIDS (Avert, 2009). Human immunodeficiency virus also known as HIV is the precursor for AIDS. Human immunodeficiency virus infects and damages part of the body's defenses so there is little fight against infections, namely the white blood cells known as CD4 helper lymphocytes (pronounced: lim-fuh-sites) (The Nemours Foundatio, 1995 - 2009). HIV is spread when the infected persons bodily fliuds such as for example semem, vaginal secrections and blood enter the body of the non-infected person. Only trace amounts of the infected bodily fliud is needed to infect a person.
CU254 - CAUSES AND SPREAD OF INFECTION - Kathryn Denton 1.1 bacteria - neither plant/animal are a group of there own, very small, normally millions of them they multiply and are a single cell with NO nucleus Virus- small infectious agent, can only replicate inside living cells of organism, have genes of DNA or RNA Fungi- multicellular micro organisms including yeasts & moulds. used for making ABx. essential in decomposition Parasite- is an organism that lives on or in another organism to the detremenet of the host. feeds off host 1.2 Bacteria - URTI, pneumonia Viruses , common cold, HIVFungi - nail infection, candida infections Parasites - Ringworm, Tic born encephalitis 1.3 Infection - invasion of the body by a foreign substance Colonisation - is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony 1.4 Systemic infection - means that the infection is throughout your body. This usually means that the bacteria have been able to invade either your circulatory system or the lymphatic system and spread.
CAUSES AND SPREAD OF INFECTION Outcome one:- The differences between bacteria, virus, fungus and parasites. Bacteria :- they are small single-celled life forms that reproduce quickly and are capable of causing disease. Antibiotics can be used to treat infections caused by bacteria although some 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. 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.
CU254 Causes and Spread of Infection 1.1 Bacteria are living things and are larger than viruses they are neither plant nor animal but belong to a group all by themselves they are small, individually they come in various shapes typically spheres and rods they are complete with organelles and a “skin” cell membrane, harmful bacteria pathogens cause disease that usually start in a specific location but when left untreated can cause septicaemia .Not all bacteria is harmful. Viruses are microscopic pathogens that infect living cells and tissues, viruses are not living things they are complex molecules of proteins and genetic material but they don’t have their own cell structure viruses can’t replicate without infecting a living cell unlike bacteria that has everything it needs to reproduce viruses need living cells in order to replicate. Fungi are multi celled organisms that are similar to plants. Parasites are also multi celled organisms but have more complex cell structure than bacteria they are larger than most bacteria and can been seen under a microscope and sometimes to the naked eye. 1.2 Common illnesses and infection caused by Bacteria include Salmonellosis, MRSA, Food Poisoning tonsilitus, gonorerhea bronchiolitis strep throat syphilis and chlamydia.
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.
Only a handful of the earthworm species are in the genus Lumbricus. There are 32 described native earthworms in the Pacific states alone. There are over 20 introduced lumbricids, plus many introduced megascolecids. This is an English language Wikipedia, not a US one, so US-only info should be used sparingly. Digestion and excretion The earthworm has a simple digestive system compared to other creatures.
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.
That’s why it’s so important to wash your hands or use hand sanitizer, it grows in numerous places. Also bacteria cells do not contain a cell nucleus and rarely harbor membrane-bound organelles, unlike eukaryotes which they all contain a nucleus. Bacteria has a wide range variety of metabolic types and that is how they are defined using their taxonomy, the three different types are phototrophs (sun light), litotrophs (inorganic compounds), and organotrophs (organic compounds). In the lab we tested our very own bacteria off of our tongue and smeared it on a blood agar plate, sheep blood to be exact. We collect the bacteria from the inside of the mouth and grow them in specially prepared petri dishes.
