Many people had different ideas on what caused the Plague. Some of the reasons included that God was correcting issues such as human wrongdoings, Jews were poisoning the Christians by putting poison in the water sources, and that an earthquake caused fumes to get into the air that people were then breathing in and becoming ill from (Marks, Geoffrey J). In reality, the plague was caused by Yersinia Pestis, which is a bacteria carried by rodents. If a rat carrying the bacteria were to bite a human, then the bacteria would enter the human’s bloodstream and would spread rapidly. The individuals that were affected had large swollen lymph nodes, high fever, and became delirious from pain (The Black Death). The most distinguishing side effect was patches on the

What is the plague? The plague or referred to as the Black Death, according to the CDC (2015), “is a disease that affects humans and other mammals and caused by the Yersinia pestis bacteria. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague”. There are three categories of a plague. There is the bubonic plague, which is the most common form. With this form bacteria infects the lymph system and causes it to become inflamed. Symptoms of this type of plague are fever, headache, chills, and swollen and tender lymph nodes, which are called buboes. Then there is the Septicemic, which occurs when the bacteria multiply in the blood. Symptoms of this type of plague are fever, chills, extreme weakness, abdominal pain, shock, and possibly bleeding into the skin and other organs. Also, skin and other tissues may turn black and die, especially fingers, toes and the nose (CDC, 2015). Then there is the Pneumonic Plague, which is the most serious form of plague and occurs when Y. pestis bacteria infect the lungs and cause pneumonia (NIH, 2015). This is the only form of the plague that can be transmitted human to human. Symptoms of this form of the plague are ever, headache, weakness, and a rapidly

I chose to do my research paper on Lyme disease. During my research, I found a lot of interesting facts about Lyme disease. The disease is caused by bacteria, called Borrelia burgdorferi, which is only transmitted to humans when they are bitten by an infected tick. Lyme disease was first discovered in 1975, in Lyme, Connecticut, after a group of children were diagnosed with juvenile rheumatoid arthritis. This eventually led them to discover the bacteria Borrelia burgdorferi. The disease was given its name in 1982, after the town of Lyme, Connecticut. According to Center for Disease Control and Prevention, Lyme disease is the most commonly reported vectorborne illness in the United States. In 2014, it was the fifth most common Nationally Notifiable disease. Lyme disease is most prevalent in the northeast and upper Midwest.

The Plague was a severe outbreak of bacterium Yersinia pestis in the 1300’s and the 1800’s. Killing 25 million people in the 14th century alone it became one of Europe's most grim times in history. The Plague caused people to flee their homes in fear of catching the Black Death. The outbreak began in Peking, China otherwise known as modern day Beijing, capital of China. The disease ended out around 1350, but still had no medically accurate way of treating the disease.

The plague was caused by bacteria known as Yersinia pestis and was common in rodent populations (“Ecology and Transmission”). When rodents, such as rats, became infected and began to die off, the fleas who were once feeding off of them needed to find a new host. During Medieval times rats lived in close quarters with humans, even infesting their ships. This neighboring proximity made it easy for fleas to carry the disease to humans (Benedictow). Not only could the plague be transmitted through a flea bite, but exposure to contaminated body fluids and tissues, such as feces and blood, could cause infection. Once a human was infected, they could transmit it through coughs and sneezing, although more rare (“Ecology and

Many people have a fear of rats, and that fear is completely justified since they were the source of a disease that killed about 200 million people worldwide, the Black Death. The Black Death or the plague is caused by a bacterial strain of Yersinia pestis. The disease is believed to have emerged in Central Asia around 1340. From Asia, the disease has managed to spread throughout the entire world. Even today, the disease still affects all parts of the world, including the United States. The disease was first found only in rats, but fleas allowed the bacteria to be transmitted to humans. Once contracted, the disease is highly contagious. This disease was especially deadly because of how it attacked the immune system.

The bubonic plague has a major impact on the lymphatic system. The lymphatic system is made up of lymph nodes, lymphatic vessels, lymphoid

Lyme disease is a bacterial infection transmitted through the bite of one of several types of ticks. Borrelia burgdorferi (B burgdorferi) is the bacteria that cause Lyme disease. UMMC (2016) asserted that

Plague is a very deadly bacterial disease. It has been a recurring force that has wiped out much of the world’s population during it’s outbreaks. The bacteria that is responsible for one of history’s most deadly diseases is Yersinia pestis. Yersinia pestis first infectes a rat. The rat is then the host for a flea. The flea feeds on the blood of the rat which is infected by the bacteria. For a reason still unknown today the bacteria started multiplying in the flea blocking it 's stomach. This caused the flea to throw up the infected rats blood into the human when it feeds on it.

The definition of plague is epidemic disease, or a disease affecting many, causes high mortality. The Black Death caused many problems and killed many people. This was a very serious plague. It traveled across Europe in 1346. The doctors tried many ways to prevent the plague. The Europeans had odd reasons on why they received the Bubonic Plague. Stated by Communicable Disease and Prevention, “This plague is a severe illness that can result in pneumonia, swollen glands, bool infection and death” (San Francisco's Department of Public Health). The Black Death, also known as the Bubonic Plague, affected European society greatly due to the numbers lost and was hard to prevent the stopping of the disease.

What is Lyme disease, and why is it important? Lyme disease is a tick-borne disease created by bacterium Borrelia burgdorferi. “The infection is primarily transmitted by Ixodes ticks, also known as deer ticks, and on the West Coast, black-legged ticks” (Lymedisease.org). It’s hard to identify the ticks because of their tiny size, similar to a poppy seed. To make that exact the female adult deer tick is about 2.7 mm in length, and the male is smaller than that (tickencounter.org). The size makes it even more difficult to feel or find a bite from the tick. However, the consequences can be very serious, sometimes even fatal (cdc.gov). Lyme disease is a serious public health in the United States that is overlooked.

Lyme is a disease that is transmitted through the bite of a tick. "It is caused by a spirochete – which is a corkscrew shaped bacterium called Borrelia burgdorferi" (About Lyme Disease. 2017). (Show Photo)

The bacteria found in the Black Plague is known as Yersinia pestis that is a bipolar and plump, lightly-staining, coccobacillus. Remaining a dangerous threat even today as well as what was previously stated that it is a plausible agent for bioterrorism. And as stated, areas such as America, Asia, and Africa are foci endemic areas. Where wild rodents, such as squirrels and rats, are the sustenance pushing for the spread and infection of the disease. The transmission being from animal-to-animal through fleas and infection to humans through contact or bites. Instances of human-to-human infection are uncommon except for the pneumonic plague, the disease caused by plague bacillus also known as Y pestis. The germ was named after Alexander Yersin who had discovered it in 1894 during a pandemic in China that started in1860. Causing numerous casualties by how fast and effective the disease was spreading, it had seemed that there was no end in

Bubonic plague has had a major impact on the history of the world. Caused by the bacterium, Yersinia pestis, and transmitted by fleas often found on rats, bubonic plague has killed over 50 million people over the centuries. Burrowing rodent populations across the world keep the disease present in the world today. Outbreaks, though often small, still occur in many places. The use of antibiotics and increased scientific knowledge first gained in the 1890s have reduced the destruction of plague outbreaks. In Medieval times, with the unknowing help of humans, bubonic plague exploded into a pandemic. Known as the ³Black Death², it decimated Europe in 1350, killing 1/3 of the

A plague is a bacterial infection that can take on more than one form. One of the greatest plagues that have stricken mankind throughout history was the Black Death. The Black Death was the outbreak of the bubonic plague that struck Europe and the Mediterranean area between 1347 and 1351. This plague was the most severe plague that hit the earth because of its origin (the spread), the symptoms, and the effects of the plague.
