Clostridium perfringens Clostridium perfringens is a bacteria which are Gram-positive, endospore-forming anaerobes, that appear to be rod-shaped. They lack flagella, but they can still migrate across surfaces using a type of gliding motility that involves the formation of filaments of bacteria lined up in an end-to-end conformation. Clostridium perfringens bacteria is most commonly found in soil, and it the intestinal tracts of humans and animals. (1,2) C. perfringens most commonly causes food poisoning, and various types of gangrene, infections from this bacteria can cause necrosis, bacteremia, and emphysematous cholecystitis. Back before the 1890’s Clostridium perfringens used to be known as Clostridium welchii.
Diarrhea is seen in approximately 10 to 20 percent of patients. After 2 to 7 days, SARS patient may develop a dry, nonproductive cough that might be accompanied by hypoxia. In 10 to 20 percent of cases, patients require mechanical ventilation. Most patients develop pneumonia. The disease is spread by close person-to-person contact through direct contact with respiratory secretions and/or body fluids of an infected individual.
This paper will focus on one of the clinically significant forms of the Staphylococci family, called Staphylococcus aureus. Staphylococcus aureus is a form of bacteria that is classified under the kingdom of Eubacteria, phylum Firmicutes, and more specifically the Genus of Staphylococcus. There are roughly thirty two species and eight sub species of the Staphylococci family, of which, only three are clinically significant. These three species are significant as they can be distinguished by coagulase production and novobiocin resistance. S. aureus has unique characteristics that cause it to interact with organisms in a manner that can cause pathogenic effects.
It infects nearly 2% of adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis. In the United States, Giardia infection is the most common intestinal parasitic disease affecting humans [1]. Giardia infection can cause a variety of intestinal symptoms, which include: Diarrhea, Gas or flatulence, Greasy stool that can float, Stomach or abdominal cramps, Upset stomach or nausea and dehydration. Symptoms of giardiasis normally begin 1 to 3 weeks after becoming infected.
This kind of Staphylococcus aureus is called “MRSA”, referred to methicillin-resistant S. aureus. This bacteria are multi-resistant to beta-lactam antibiotics, meaning that they are resistant to different kinds of antibiotics, such as penicillin, methicillin, dicloxacillin and cephalosporin. As the process goes, that normal Staphylococcus aureus are being killed by penicillin antibiotic, and the ones that are resistant survived and keep on reproducing, Staphylococcus aureus bacteria that is penicillin resistant spread in the community and its amount kept on increasing. This made natural selection to occur, which the bacteria that are antibiotic resistance are suitable ones and they survived in
In this paper all three of the main types of botulism will be discussed. C. botulinum is an anaerobic, (conditions without oxygen). Gram positive, spore-forming rod shape bacteria that produces a botulinum toxin. This toxin (Botulinum toxin) acts by blocking the production of acetylcholine at synapses. (Chaudry, 2011, para.
Symptoms of Pleurisy last anywhere from a few days to 2 weeks. The main symptom of pleurisy is a sharp or stabbing pain in the chest that gets worse with deep breathing, coughing, sneezing or laughing. The pain may stay in one place, or it may spread to the shoulder or back. Sometimes it becomes a fairly constant dull ache. Depending on its cause, pleurisy may be accompanied by other symptoms, such as, shortness of breath, fever and chills, rapid shallow breathing, unexplained weight loss, sore throat followed by pain and swelling in the joints, diarrhea, erectile dysfunction, and vomiting blood.
Both disease's have flu-like symptoms such as fever, headaches, weakness, chills, and sore throat. In addition, Ebola and Black Plague, specifically Pneumonic Plague, can be contacted by human to human contact specifically through blood or bodily fluids seeping into broken skin. Once the Ebola virus transmits to humans, it takes two to twenty one days to show the flu-like symptoms. For the Black Plague, specifically the Bubonic and Septicemic plague, it takes about three to seven days to show flu like symptoms. For the Pneumonic plague, symptoms will automatically develop within one to three days after exposure to bacteria.
Atherosclerosis is a multi focal, smoldering immunoinflammatory disease of medium sized and large arteries filled by lipids. (Curtis M. Rimmerman, 2008) When plaque builds up the condition is called Atherosclerosis, the build up of plaque over many years.If the flow of oxygen rich blood to your heart muscle is reduced or blocked, Angina or a heart attack can occur. Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. Pain can also occur in the shoulders, arms, neck, jaw or back.
(1) Definition: Lung inflammation caused by bacterial or viral infection. (2) Pathophysiology: Pneumonia is an excess of fluid in the lungs resulting from an inflammatory process. It is an acute infection of the alveoli. This is a global problem, and the WHO (World Health Organization) suggests that it is the most common cause of death in children and that 1.4 million die each year as a result of pneumonia. Pneumonia may also occur as a complication in hospital settings, secondary to surgery.
