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.

Chapter 22 skin infections * Skin infection - can kill you, mess with your bones, tissues, skin infection, heart valve infection, food poising * Staphylococcus aureus(staff) * Purple cluster spheres * Why is staff so pathogenic (disease causing) Pathogenic mechanisms of Staph.aureus * leukocidin * It kills your white blood cells * Coagulase - factor that makes your blood clot * With clotting white blood cells are not able to help fight off cause they are blocked * Protein A * They are Y shaped * Protein A binds to antibodies * They form by the ends off the tips off the top of the Y * Binds antibodies in the wrong direction so it will not trigger antibodies
b) Halons are a group of chemical compounds with one or more halogens linked making them a type of organic halide. Halons were key ingredients to certain aerosol sprays such as deodorant and hair spray. The elimination caused manufacturers to alter the chemical makeup of the sprays, and quite frankly turned me to using solid deodorant as opposed to aerosol sprays. c) Carbon tetrachloride is one of the most potent hepatotoxins, meaning it is very harmful to the liver. This compound was once used as a pesticide for killing insects in stored grain.
Fungi Fungi are skin infections caused by dermatophytes and yeasts, which are groups of fungi that are normally harmless. When these grow excessively, it causes symptoms and usually affects your skin because they live of keratin. Parasite A parasite is a life-form that survives off its host, including worms, bacteria, protozoa and amoeba. Parasites often work by stealth—you probably don’t even notice their presence. In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body.
It has been recorded at a number of sites within the park. The fungus has the potential to impact of the vegetation, especially along the heathy ridge tops where grass trees are dying. It also affects a lot of the native vegetation and causes the death of a lot of other species. The disease spreads naturally but also through infected soil when transportation travel over it. Quarantine and vehicle hygiene to limit the spread can only be achieved my
A counter argument to one of the disadvantages of genetically modified food Some antibiotics can be transferred to humans and make it harder for us to fight infections, genetically modifying foods could potentially put farmers out of work, and some important insects could be at risk because of the insecticides in foods. 6.

The plague bacilli are little toxin factories. The heat of the human body signals the thousands of bacilli injected by the flea to go into a special production. If the immune system manages to kill some, the germs release more poisons from their dying bodies. Meanwhile, they work their way into the fluid drainage system to travel. If the flea bite was on the leg, the lymph drainpipes carry plague to the lymph nodes in the groin.
