Background Strongyloides stercoralis is a soil-transmitted helminth that penetrates the skin as a method of infection. This parasitic worm gains nutrients and shelter from its host, while causing malnourishment or harm to the diseased. The infective filariform penetrates the skin from infected soil and migrates to the lungs through the blood stream. In order to mature the filariform larvae are coughed up and swallowed to develop into adults in the intestines. The diagnostic stage is the rhabditiform first stage larvae in feces.…
Black Death -The bacterial disease that atrophied Europe between 1347-1351, taking an equitably greater amount of life than any other known epidemic or war up to that point. The Black Death is broadly thought to have been the result of infection by the bacterium Yersinia pestis. 5 Facts: • Many doctors believed that bad smells could force out the plague. Therefore, treatments for the disease included applying feces and urine, and other substances that were much more likely to spread disease than to cure it. • Y. Pestis utilized the flea by blocking its digestive tract.…
Abstract Smallpox is a highly infectious disease caused by the Variola virus. This report explores the taxonomic classification, “life cycle”, and mechanism of replication of this pathogen, as well as discusses the virulence and treatment options for an infected human host. This member of the Orthopoxvirus genus is extremely virulent, and has a fatality rate of nearly 30%. While this virus only attacks a human host, similar members of the Voxviridae family produce similar infections in animals.…
The Funerary Monument of Flavius Agricola is a Roman marble piece by Antonine that is now on display in the Indianapolis Museum of Art. The sculpture was first found in 1626 under the floor of the Vatican when Bernini’s famous altar was being put up. After the monument was found, it was added to the collection of Cardinal Bernini. In the sculpture, Flavius Agricola is laid out in a semi relaxed position on what appears to be the lid of a coffin that has had a high back and a high side at his head and at his feet.…
In maryland, a doctor named Theodore Nash takes on many patients that have tapeworms in their brain. Most of the time tapeworms are found in people’s intestines in their adult stage but before their adult stage they go through a larvae stage. Sometimes the tape worms in their larval stage can get into people’s brains and cause the illness called neurocysticercosis. This illness is easily confused with other brain disorder which has made it hard for doctors to know how many people are affected with neurocysticercosis. At minimum there are 5 million cases of it.…

The process of natural selection makes it so organisms with characteristics further suitable to their environment outlive and reproduce more than those with less suitable characteristics. This process helps ensure that each generation becomes increasingly adapted to their surroundings so that they can ultimately live longer and increase population sizes. At first glance, diseases are the exception to this principle since they seem to be unfavorable attributes that have somehow continued to pass down the generations. But what if each disease has actually contributed to human survival at some point in time? This is Dr. Sharon Moalem’s exact notion in his book “Survival of the Sickest”.…
DFTD is primarily seen inside the oral cavity with tumors developing primarily around the face and jaw, but can then metastasize (Grueber et al., 2011). In extreme cases, the tumors may also be seen extending to the neck and other parts of the body. These tumors can grow large and fester making eating a challenge which ultimately kills the animal (Jones & McCallum, 2011). All individuals who contract the disease die within six months as a result of starvation because of an inability to feed or as a result of organ failure from metastases (Grueber et al.,…
Cryptococcus gatti or C.gattii is a rare fungal disease that can infect many animals as well as humans. C.gattii lives in sub-tropical and tropical environments such as the Pacific Northwest, Hawaii, Alaska, Mexico, here in Georgia, and in other United States owned islands. C.gattii, as previously stated, is a rare infection, and it will mainly occur in people who have weakened immune systems. C.gattii is a dangerous disease. Unfortunately, its symptoms are very generic to many other illnesses.…
When there is a dense population of both humans and rats, the probability of a disastrous pandemic increases due to the dense community, yet compact, shrunk amount of land, which is known as a ‘plague focus’ or a ‘plague reservoir’. To that end, the black rat (‘ship rat’ or ‘house rat’) was the primary suspect for the spread of disease since they lived in close quarters to society. Consequently, within ten to fourteen days Yersinia pestis would contaminate the rat colony, which would leave a plethora of Xenopsylla cheopis without a host. Nonetheless, after three days, the rat fleas would transition their source of food from the black rat to a human. As a result of the flea bite, the contagion would affect the host [human] by draining into…
following. The Great Plague (black death) is now among us; roaming the streets of London. We believe god is punishing us for our sins, and that were are still not worthy enough for him. It is killing our loved ones and has attack many around us, prithee be aware of your surroundings, and those around you.…
The plague killed more than 25 million people around the world. The plague had lots of causes and effects. Most people in Europe experienced The Black Death. The plague’s cause sparked scientists all over the world.…
The bubonic plague is a deadly bacterial disease transmitted by fleas and rats (Mayo Clinic). It is uncommon during recent times, there are only about five thousand worldwide diagnoses a year, and about nine in the United States (Mayo Clinic). During the 14th century, this disease was behind the death of one third of Europe’s population (The Editors of Encyclopaedia Britannica). The bubonic plague is primarily a disease of rodents and fleas, and humans only accidentally enter the usual cycle of rodent-flea-rodent (The Editors of Encyclopaedia Britannica). Bubonic plague is a bacterial disease; it has a violent history, and the severe disease can be cured (The Editors of Encyclopaedia Britannica).…
The Bubonic Plague was a deadly disease that killed at least twenty-five million people and devastated Europe from the 1300’s to the early 1700’s. The Bubonic Plague is also known as the Black Plague and the Black Death. The Bubonic Plague is a disease that was very deadly. Many religious people thought the disease was an act of God. They thought that God was punishing them for the sins they have committed in life.…
(24). III. Francisella tularensis Francisella tularensis is a fastidious (requires cystiene), aerobic, gram-negative, coccobacilli, non-sporulating, non-motile bacteria (25, 26). Francisella tularensis causes Tularemia. It is spread by bites from insects like deerflies, ticks.…
