Systemic fungal infections are when the fungus gets into the blood stream and can cause serious diseases. Parasites are micro-organisms that live off their host to survive. Some parasites simply need a host to live on and don’t cause their host any problems. Others grown
For instance, Lactobacillus acidophilus — a harmless bacterium that resides in your intestines — helps you digest food, destroys some disease-causing organisms and provides nutrients. Many disease-causing bacteria produce toxins — powerful chemicals that damage cells and make you ill. Bacteria can multiply very rapidly if given the right environment. Viruses are much smaller than cells. In fact, viruses can only be seen by electronic microscope. To reproduce, viruses invade cells in your body, hijacking the machinery that makes cells work.
Typical Viruses are illnesses like smallpox, measles, mumps and tuberculosis etc which can be contracted by touch or being within an environment that has the virus in the air. Fungus or Fungi can cause such Infections like Athletes foot, Chlamydia and Thrush. Parasites because of the way they transfer from host to host mainly by contact and can cause infections such as Malaria, Ringworm, Fleas, nits etc. (3) A description of the terms ‘Infection’ and ‘Colonisation’ are that an infection can lead to a colonisation if un monitored or un treated. An infection would be
Others exist in the environment as spores of moulds A parasite is an organism that lives on or in another organism, harming the host. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacteria Tuberculosis Urinary tract infections Viruses Influenza Herpes Chickenpox and shingles Fungi Ringworm Candida Parasites Malaria Tapeworms 1.3 Describe what is meant by ‘infection’ and ‘colonisation’ sometimes we can have a disease causing organism living on/in us but not be showing symptoms of illness this is known as colonisation. If the organism is making us ill this is infection. 1.4 Explain what is meant by ‘systemic infection’ and ‘localised infection’ A systemic infection is in the bloodstream and has spread or is spreading around the body. They normally spread through the bloodstream and most of the infectious diseases known to the general public are examples of systemic infections (AIDs, flu, tuberculosis) Localised infections remain in one part of the body and do not cause problems
1.1 & 1.2 Bacteria~ These are single cells that can divide and multiply rapidly and come in different shapes and divide anywhere such as M.R.S.A, septicaemia and gastro-enteritis. Viruses~ Are ready made stable D.N.A with a protective shell, they cannot invade without the assistance of another cell to do so, examples of these are the common cold, flu and hepatitis. Fungi~ Are simple plants such as yeasts and moulds or even rusts that thrive in moist, dark, unventilated areas like thrush, ringworm or athlete's foot. Parasites~ Are animals or plants living in or on the host, usually small creatures that are living on or within us such as lice, scabies, tapeworm or threadworm. 1.3 What is meant by….
This bacterium is also a facultative anaerobe meaning it can grow with or without oxygen. The bacterium is found most commonly in animals such as rats, fleas, lice, chipmunks, etc. Y. pestis is most commonly transferred through bites from affected animals, direct contact with infected tissue or body fluids, or inhaling infected droplets. The best way to avoid the plague would be to stay away for any animal that has potential for having Yersinia pestis If proper safety measures are not taken and a human ends up with the plague they would have general symptoms such as inflamed lymph nodes, fever, chills, muscle aches, headache and weakness. If left untreated the symptoms could worsen and you could be left with septicemia, food poisoning like symptoms, bleeding from under the skin, in the urine, from the mouth and nose, shock, kidney failure, breathing problems.
It begins at the site of a break in the skin (a surgical or non-surgical wound). In order for someone to contract necrotizing fasciitis, the bacteria must be introduced into the body. Group A Strep is the same bacterium that causes strep throat This group of bacteria is responsible for mild cases of sore throat (pharyngitis), skin infections, as well as rare, severe illnesses such as toxic shock syndrome and necrotizing fasciitis. However, there are various strains of the bacteria, some of which are more powerful than others. With the right set of conditions, necrotizing fasciitis is a real risk and can cause severe damage.
1.1 Identify the differences between bacteria, viruses, fungi and parasites Bacteria - a single cell micro-organism that gets its nutrition from its surroundings and can only be seen under a microscope. Viruses - are disease producing agents far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy. Fungi – are included in the plant kingdom but are quite different from green plants. The basic unit of a fungus is a hypha which is a hollow tube.
Causes and Spread of Infection 1. Understand the causes of Infection 1.1 Identify the differences between bacteria, viruses, fungi and parasites The differences between bacteria, viruses, fungi and parasites range. One of which is the fact that viruses and parasites depend upon a living host to survive, while bacteria and Fungi's don't always need to do so. Another difference is that Parasites are normally living creatures - ticks, fleas, worms - whilst bacteria, viruses and fungi are cells that have different cell coatings. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites The most common illnesses and infections that occur due to bacteria, viruses, fungi and parasites are Dioreah, Vomiting, Influenza, Nail infections, Tick bites, Colds, Skin Conditions, Digestive Problems ( Parasites - Worms ) and in some cases, Death.
Answer: The disease spread by fleas being carried around on rats. In the filth and the warmth of the summer heat, the rotting rubbish is a perfect place for bacteria to breed. People living in the infected area had to sanities in order to try and prevent the disease from spreading. When people died from the plague, they hardly every let anyone see the deceased to try and stop the spread. Bubonic plague Is a zoonotic disease, circulating mainly among small rodents and their fleas, and is one of three types of bacterial infections caused by Yesinia pestis (formerly known as Pasteurella pestis), which belongs to the family Enterobacteriaceae.
