Typhoid Fever Typhoid fever is an intestinal illness, which can result in great suffering and even death. At first it was commonly confused with other fever causing illnesses until 1869 when William Jenner performed a careful analysis and found differences in the different types of typhus fevers. In this paper, I will discuss the bacteria that causes typhoid fever, discuss the signs, symptoms, method of transmission, past and current epidemics, and whether or not there has been a decrease in outbreaks in the past few years. Typhoid fever is caused by the bacterium Salmonella typhi, a member of the genus Salmonella, which is included in the Enterobacteriaceae family. Salmonella typhi cells are aerobic, gram negative rods that affect the gastrointestinal tracts of humans, and occasionally the bloodstream.
Scarlet fever is caused by streptococcal (strep) bacteria, the same bacteria that cause strep throat. There are many different strains of strep bacteria, some of which cause more serious illness than others. The type of strep that infects the throat and causes scarlet fever is called group A beta-hemolytic streptococcus (GABS). What are the symptoms of scarlet fever? Symptoms that may occur before the rash include: ?
This is great for historians because it allows us to see exactly what was happening at the time, for example, if a certain disease was a greater killer then another. Cholera and Influenza were most likely the biggest killers of the 19th century, with 3 major cholera epidemics (in 1832, 1848 and 1866) and regular flu epidemics. Cholera affected all ages and was contracted from contaminated water. Influenza affected all ages, especially the weak, and spread through the tiny droplets of moisture in the nose produced from sneezing or coughing. Tuberculosis was one of the worst diseases, it infected when the bacteria spread in the moisture produced when coughing, and affected all ages.
The first stage of symptoms includes; fever, chills, severe headache, sore throat, and muscle aches. The second stage of symptoms include; vomiting, diarrhea, seizures, and respiratory failure. The bacterium travel to the immune system and began to break it down and then travel to the lymphatic vessels to find lymph nodes to feed on. The nodes eventually become inflamed and warm to the touch and irritated. The swollen nodes are called buboes, which is what gives the bubonic plague its name.
Now the infection is spreading all over the tissues through out the body. They also trigger the body’s immune system, which causes the symptoms. When the measles virus infects the immune system and interacts with the antibodies and T cells, a measles rash begins on the face and very quickly spreads to the body, arms and legs. The fever and cough become more intense after the fifth day. The rash turns into 3-4 mm red maculopapular lesions, which are flat and slightly raised.
MRSA is a strain of the staph bacterium that has grown resistant to the usual treatment of methicillin, which gave the disease its name Methicillin-resistant Staphylococcus Aureus. It was first noticed in the early 1940’s but has grown increasing dangerous in the past few years (Gilboy 1). One of the first signs is a small red bump that will appear to be a spider and can quickly turn into a life-threatening ailment. In the bacteria’s later stages it can cause things such as necrosis of soft tissues and even hemorrhaging pneumonia (Gilboy 1). There are two forms of MRSA, Community-acquired (CA) and Hospital-acquired (HA).
Why should people donate their money to the Cystic Fibrosis foundation over other foundations? The answer to this question can be broken down fairly easily. The main reason people should donate to this foundation is because of the incredible strides the foundation has made in such a short amount of time. The money being used is being put towards finding a cure for the disease. Until a cure is found, scientists and doctors are continuing to find ways to expand the life span of these patients with new medicines.
A painful, pus-filled scab may indicate a secondary infection mainly with streptococcus or staphylococcus . The cutaneous form of anthrax accounts for 95 percent of all cases globally . The case fatality rate for cutaneous anthrax is 5 to 20 percent . If left untreated it can lead to septicemia and death. Death can occur through asphyxiation from the edema if the lesion is around the head or neck .
The pneumonic plague occurs when the bacteria affect the lungs and causes people to get pneumonia. Of the three forms, the pneumonic is the most dangerous (Plague- Bubonic plague). The most common form of the disease, bubonic, is diagnosed by the swollen lymph ... ... middle of paper ... ...2013 Tucker, Brandon. Yersnia Pestis. Missouri University of Science and Technology.
Cholera Cholera is an infectious disease cause by bacteria that affects the absorption of water in the small intestine. Sever cases cause violent diarrhoea. It is the huge amount of fluid loss, which makes cholera so dangerous. If the fluid is not replaced the body becomes dehydrated and you could die within twenty-four hours. Treatment of cholera is simple; replace the fluid lost with the right mixture of sugar and salts.
