Infections That Are Caused By Pathogens
Pathogens are microorganisms that cause diseases are called pathogens. They are specialised to infect the human body tissues where they reproduce and cause damage that gives rise to the symptoms of the infection although this may happen the body is very good at repairing itself as the body fights back by mobilising its immune system to fight of the infection.

Infection is an invasion by a multiplication of pathogenic microorganisms in a bodily part or tissue which may produce subsequent tissue injury and progress to overt disease through a variety of cellar or toxic mechanism

here are some of the zones in the body showing how pathogens cause infections and disease

Pathogenic microorganisms can be spread from person to person in a number of ways. Not all pathogens use all the available routes. For example, the influenza virus is transmitted from person to person through the air, typically via sneezing or coughing. But the virus is not transmitted via water. In contrast, Escherichia coli is readily transmitted via water, food, and blood, but is not readily transmitted via air or the bite of an insect.

While routes of transmission vary for different pathogens, a given pathogen will use a given route of transmission. This has been used in the weaponisation of pathogens. The best-known example is anthrax. The bacterium that causes anthrax—Bacillus anthraces—can form an environmentally hardy form called a spore. The spore is very small and light.

Pathogenic microorganisms can grow on currents of air and can be breathed into the lungs, where the bacteria resume growth and swiftly cause a serious and often fatal form of anthrax.

    When harmful microbes, or germs, enter the body, they multiply and cause disease. This is called infection. Your body's defences usually do a killer job of squelching harmful microbes. But sometimes germs multiply faster than the body can handle -- and you get sick. People come in contact with germs in many ways, including:…

    Infections happen when the body is invaded with micro-organisms like bacteria, viruses and parasites that are not normally inside the body Colonisation is the development of a bacterial infection on/in an individual, the individual becomes a carrier of the infection but may have no signs or symptoms of illness, although they do have the potential to infect others. 1.4 Explain what is meant by systemic infection and localised infection. Systemic infections affect the whole body – Flu / HIV, while localised infections are limited to one area of the body – ear / eye infection. 1.5 Identify poor practices that may lead to the spread of infection. Poor personal hygiene, incorrect disposal of rubbish / waste / chemicals, not washing hands, not wearing PPE, not storing or cooking foods properly, not cleaning your surroundings, not covering your nose or mouth when sneezing or coughing, sharing towels, tooth/hair brushes, not following policies or reporting outbreaks / episodes of disease, direct contact with bodily fluids and waste. |…

    Anthrax is an infectious disease which is caused by the spore forming bacterium Bacillus anthracis. Anthrax can be deadly if the symptoms haven't been caught in time for treatment. Anthrax infection can occur in three forms: cutaneous (skin), inhalation, and gastrointestinal. B.Anthracis spores can live in the soil for many years and humans can be infected with anthrax by handling animal products from infected animals or by inhaling anthrax spores from contaminated animal products. Eating uncooked meat from infected animals can also spread anthrax. Anthrax can also be spread by biological warfare. Any country that has biological warfare capability can use anthrax on its warheads to spread anthrax (FAQs1).…

    Another way is through inhalation of anthrax. Inhalation anthrax is a very serious disease, and unfortunately, most affected individuals will die even if they get appropriate antibiotics. This is because antibiotics are effective in killing the bacteria, but they do not destroy the deadly toxins that have already been released and traveled through the body. This affects the body by entering into the lungs, and then the spores get picked up in the lungs by scavenger cells called macrophages. Most of the spores are killed, but unfortunately some survive and are taken to the glands in the chest called lymph nodes. In the lymph nodes, the spores that survive multiply, produce deadly toxins, and spread throughout the body.…

    Bacteria can get into your body in many ways; the first one is Droplet infection so when you cough, sneeze or talk you expel tiny droplets full of pathogens from your breathing system and then other people breathe that in. The second is Direct Contact which means that some diseases are spread by direct contact of the skin. The third is through contaminated food and drink so when you eat raw or undercooked food or you drink water containing sewage can spread disease for example diarrhoea and food poisoning (salmonella). The fourth is being infected by bacteria through any animal or insect bite for example malaria is spread by a mosquito that contains the malaria virus biting you.…

    Bacteria: These are tiny microorganisms, they cannot be seen with the naked eye. They exist on virtually every living thing or object in the environment i.e. dirt, water, caves, trees, dead animals, and within everybody living on earth. Its nutrition is from its surroundings. We carry bacteria in the body, mainly in the intestines, on the genitalia or on the skin. Bacteria can be good or bad. It can help our immune system but there are bad bacteria which make you become ill. Meningitis is a bacterial infection, this can be life threating to a young baby and is most common in young children. It is an infection of the membranes covering the brain and/or spinal cord, this is a reason it can be life-threatening. MRSA is another big bacteria illness, this commonly affect hospitals and is due to lack of hygiene. Food poisoning is a common cause of illness caused by bacteria. This is because bacteria lives on food. If cooked and food has not reached a high enough temperature to kill off bacteria then it can cause the bacteria to rapidly grow and cause sickness to a person. The types of food poisoning are; salmonella, E. coli, norovirus, campylobacter, listeria, clostridium perfringens. These are also linked with viruses too. Also most sexual transmitted diseases are a bacterial infection i.e. syphilis, gonorrhea. Also Lyme disease, this is spread by the bite of a deer ticks most common around wooded, rural areas. If untreated it causes an arthritis-like condition that can last for months.…

    Bacillus anthracis, the bacterium which causes anthrax, is rod-shaped and about 1 by 6 micrometres in size. It was the first bacterium ever to be shown to cause disease by Robert Koch[4] in 1877. The bacteria normally rest in spore form in the soil, and can survive for decades in this state. When ingested by a plant eating animal, the bacteria starts to multiply and eventually kills the animal. They even continue to reproduce in the carcass but eventually revert back to the dormant spore state when they run out of nutrients. (“Bacillus anthracis.”)…

    Infectious disease is any disease that is able to spread among our public and contained population, thus being called infectious. An infectious disease travels through the environment, as it passes from one person to another through means of airborne, droplets, contaminated water, clothes, bedding, utensils or anything that has come in contact with an infected person. Diseases spread as the result of direct personal contact with bacteria.…

    Infectious diseases are caused by pathogens; any organism that causes disease. Pathogenic microorganisms include bacteria, fungi and viruses. Pathogens cause disease by producing toxins and damaging cells. An example of a disease causing pathogen is the cholera bacteria, Vibrio Cholerae. Cholera is a bacterial infection caused by drinking contaminated water or eating good that has been in contact with contaminated water, with symptoms including severe diarrhoea and stomach cramps. The cholera bacteria produces a toxin that affects chloride ion exchange; it causes the chloride ion protein channels in the plasma membranes of the small intestine to open, changing the water potential of the intestine and causing the body to become extremely dehydrated. Another example of a disease caused by bacteria is Pulmonary Tuberculosis; a bacterial infection spread through inhaling tiny droplets from the coughs or sneezes of an infected person. The responsible bacteria is called Mycobacterium Tuberculosis, with typical symptoms including a persistent cough, weight loss, a high temperature and tiredness and fatigue.…
