Bacteria:
Bacteria are microorganism’s that thrive in warm and moist conditions such as tropical oceans, the human body and in soil among others. Bacteria are split into two types of cells which are prokaryotes and eukaryotes, the main difference between these cells is that the organelles in eukaryotes are surrounded by membranes while prokaryotes do not have their organelles surrounded by membranes. Bacteria aren’t all harmful, in fact some have good uses such as helping with digestion in the human body and also some are used to curdle milk into yogurt. For example a disease that is caused bacteria is cholera. Parasites:
Parasites are organisms that live in or on a host to get their food and nutrients they need from said host. Endoparasites

The Ebola virus, being from the virus pathogen, isn’t a living organism and therefore invades host cells and takes over the nucleus which allows it to replicate itself and survive. The disease itself is spread by any type of fluids such as saliva, blood, moisture from breathing and also it can be present in a male’s semen. In the body it spreads via the blood stream and infects healthy organ cells causing them to be damaged and killed, which leads to internal bleeding and in some cases organ failure. In the West Africa outbreak, 28,000 cases of Ebola were reported with 11,000 of those cases proving to be fatal (as reported by the world health organisation). One of the symptoms of Ebola is that on the renal systems and the liver and that is that their function is significantly reduced and that can be followed by internal and external bleeding e.g. bleeding from the eyes, ears, nose or mouth …show more content…
Ebola forms clots in the blood vessels of someone that is infected with the disease, and also decreases the blood flow around the body by thickening the blood so as to give severe blood loss to critical organs around the body such as the lungs, brain, heart and many others. If blood clots form near the brain then it causes a stroke which can potentially prove to be fatal, if blood clots form near the heart then it can cause heart attacks and if it forms near the lungs then it can cause pulmonary embolism which is a massive clot in the pulmonary artery cutting off blood to the lungs. If any of the major organs blood supply is disrupted it can prove to be quickly fatal as the organ completely fails and will cause the person to die. A person with Ebola needs to have their blood thinned constantly to stop critical organ systems being affected otherwise; it can have a significant chance to prove
After the death of Charles Monet, the stage is set for much more to come. At the time, Monet’s death was considered unknown, because the Ebola virus was not known about at the time. Medication and antibiotics have no effect on someone with the virus, so obviously it’s pretty serious. Ebola is probably one of the most disgusting things anyone could ever imagine. What is basically does is turn your internal organs into liquid that then pours out of every single hole in your body, even the pores in your skin. Another effect of this virus is coughing up your own blood. This happens because the blood clots in your arteries and veins, which forces it to come out of your mouth and other areas. Eventually your skin will just explode from the pressure of all the blood built up in-between your skin and flesh. This virus can be very deceiving because it has the regular symptoms of diseases like malaria and typhoid fever, but it can kill you within a matter of 10 days.
the definition of parasite, is something that hurts. for ever. this parasite, was a landmine. I had good medical attention. But once i returned home, I finally left. I wanted to leave. there were rockets, raining down in every place i looked. those rockets stole my family. we couldn't stay. so we fled. the last time i had a true education, was when i entered high school. between 2nd grade and 9th the education i had in my birth place, that wasn't any kind of education. i wanted more. and there was nothing there for me to want
Merriam-Webster defines ‘parasite’ as ‘an organism that lives in or on another organism and benefits by deriving nutrients at the host 's expense’.
Ebola Zaire, a type of strain of Ebola, attacks every organ and tissue in the human body except skeletal muscle and bone. Small blood clots begin to appear in the bloodstream. The blood then thickens and slows, and the clots fit together in a mosaic. The mosaic thickens and throws more clots and the clots drift through the bloodstream into the small capillaries, where they get stuck. This shuts off the blood supply to various parts of the body, causing dead spots to appear in the brain, liver, kidneys, lings, intestines, and all through the skin.
The Ebola virus has effects on your internal body as well. You would also experience internal bleeding. After about five days of infection your internal organs basically liquefy. The Ebola virus destroys the cells in your liver and the lining of all internal organs. At this point you will most likely die of the virus. The people who survive the virus usually had a less direct infection like close contact.
Bacteria are one cause of infectious disease. Bacteria are a single-cell microorganism that is very common in our bodies. Less than one percent of bacteria will actually make us sick. Some of the more common infections caused by bacteria include strep throat, salmonella, and e-coli. Strep throat is common in children and causes a painful sore throat. Strep is usually treated with antibiotic medication. Salmonella is spread on food that is contaminated by human or animal...

Ebola can be spread in a number of ways. Ebola reproduction in infected cells takes about eight hours. Hundreds to thousands of new virus cells are then released during periods of a few hours to a few days. In most outbreaks, transmission from patient to patient within hospitals has been associated within the reuse of needles and syringes. High rates of transmission in outbreaks have occurred from patients to family members who provide nursing care without barriers to prevent exposure to blood, other body fluids such as, vomit, urine and feces. Risk for transmitting the infection appears to be highest during the later stages of illness. Those symptoms include vomiting, diarrhea, shock, and frequently hemorrhaging. Even a person who has recovered from the symptoms of the illness may have the virus present in the genital secretions for a short time after. This makes it possible for the virus to be spread by sexual activity. Complete recovery is reached only when none virus’s cells are left in any body fluids. This is quite rare.
The Ebola-Zaire branch was the first to be recognized and has the highest death rate of 89 percent. The Ebola-Sudan subtype has a death rate of 53 percent, and the Ebola Haemorrhagic Fever virus as a whole having a 68 percent death rate. Since the Ebola virus has not been recognized for a long time, it cannot be said for sure how it is transmitted though it is believed to be zoonotic, meaning that it is transmitted by animals and from contact with the virus, making it spread quickly through family and friends. It also transmits itself nosocomially, where it can transmit quickly through a health care environment, like a hospital. This is especially dangerous in places like Africa,...
When one thinks of bacteria, what comes to mind? Bacteria are single celled organisms whose main objective in life is to gather nutrient and reproduce asexually. They just grow and divide. Humans have very interesting interactions with bacteria. In our bodies we have one trillion cells that make us who we are. Outside and inside our bodies, we have 10 trillion bacterial cells that help us (dietary functions like making vitamins, creating a barrier against foreign/bad bacteria, helping our immune system, etc.). In terms of DNA, we have 30,000 genes. Bacteria in and on our bodies have about 300,000 genes. So really, we are more bacterial than human, proportionately speaking. Bonnie Bassler and her team worked to figure out just how these small organisms communicate with each other, and what they found is actually quite interesting.
A parasite is a creature that has a dependence on something else for existence or support without making a useful or adequate return.
In 1976 the first two Ebola outbreaks were recorded. In Zaire and western Sudan five hundred and fifty people reported the horrible disease. Of the five hundred and fifty reported three hundred and forty innocent people died. Again in 1995 Ebola reportedly broke out in Zaire, this time infecting over two hundred and killing one hundred and sixty. (Bib4, Musilam, 1)
One of the current major concerns in the world is the outbreak of Ebola. Ebola is a infectious disease that comes from the Ebola virus and it can cause death if the patient is left untreated. The disease can be managed with treatment of the patient, however. Ebola is a disease that is a major concern in the Subsaharan African Realm, and in the North American Realm,but it is beginning to be dealt with sufficiently in the Northern American Realm.
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
If certain types of bad bacteria were growing in your home and scientists knew how to keep that bacteria from spreading quickly, it could help people with serious health conditions. B. Background Information When you hear the word bacteria, the first thing that might come to mind is a germ. Although there can be many harmful types of bacteria, it is an essential part of life. Bacterium is all over the world and can be found in anything. Bacterium is one of the earliest life forms on Earth, and it plays a big role in how the Earth was developed.
