First, it was from the bacterium known as Yersinia pestis. (Wade, 2010) There are three different forms of the plague. The first is the Bubonic Plague, which is the most common form, known for its buboes, which are painfully swollen lymph nodes in the armpit, groin or neck. Septicemic plague, which spreads in the bloodstream, comes either via fleas or from contact with plague-infected body matter. Lastly there is the pneumonic plague, the most infectious type, is an advanced stage of bubonic plague when the disease starts being passed directly, person to person, through airborne droplets coughed from the lungs.
There are several types of parasites such as Ectoparasite- which is a parasite that lives on the host’s surface, examples will be hair and body lice and mites. Endoparasites – One that lives inside the host, for example heartworm, tapeworm and flatworms. Epiparasite- This one feeds on another parasite. For example, fleas and ticks. 1.2 Identify common illness and infections caused by bacteria, viruses, fungi and parasites.

If the flea bite was on the leg, the lymph drainpipes carry plague to the lymph nodes in the groin. If the bite is on the hand, plague rides the pipes to the armpit nodes. In the nodes, a massive battle begins to take place. The bacilli release toxins, the body sends immune system cells, and then the node swells with the dead of both armies and coagulated blood. This forms a bubo.
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. 1.3 Describe what is meant by “Infection” and “Colonisation” As defined by : www.freedictionary.com INFECTION Invasion by and 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 cellular or toxic mechanisms. This means that Infection is the process of infecting or being infected. COLONISATION A mass of microorganisms in a culture that originates from a single cell. This means that when either a Virus, Bacteria, Fungi or parasites in the single form, gather and join to make one mass of either Virus, Bacteria, Fungi or parasites.

The three types of plague are bubonic, pneumonic, and septicemic. Bubonic plague is the most common of the three types and is named after swollen lymph nodes called buboes. Buboes occur when the bacteria are localized in the lymph node and rapid replication occurs. Buboes associated with Bubonic Plague are located in the armpit, neck or the groin area. Common symptoms are acral necrosis of the extremities (such as the toes, fingers, lips and tip of the nose), high fever, nausea, vomiting, and breathing difficulty.
Crohn’s Disease Anatomy & Physiology Ashley Goodnight Crohn’s Disease Anatomy & Physiology Ashley Goodnight Abstract I am writing my paper on Crohn’s disease. In this paper you will find information on this disease and how people are affected. I will be explaining sign and symptoms, who may be at risk, and treatment options. Crohn’s disease is a chronic disorder of the digestive system. Crohn’s disease can affect any area of the gastrointestinal system from the mouth to the anus.
The cause that initiated this tremendously, horrible disease was the Xenopsylla cheopis (rat flea) transmitting the bacteria Yersina petis that led to start of this catastrophe. The rat flea survived as a parasite that bit and sucked the blood of its host, including the black rat, which was the principal carrier of the plague (Dunn 8). Researches have concluded that this disease was an unusual and difficult development. One reason being, that the fleas were not attracted to human beings, but to rodents. The disease was carried on even with the death of the infested rat by the rat fleas.
Disease Research Short Paper [pic]Disease Topic : elephant disease. Etiology it is caused by parasitic worms invading the body's lymphatic system - the network of vessels carrying infection-fighting cells. The worm is spread by mosquitoes, who pass it on when they take blood from humans. The bacteria-containing worms lodge in the lymphatic system, producing millions of minute larvae which spread throughout the bloodstream. It is unclear whether the swelling, or lymphoedema, that occurs results from the obstruction of the lymphatic vessels or from the response of the body's immune system to the worms and the bacteria within them.
