From the Paper "As noted earlier, Proteus vulgaris is present in the gastro-intestinal tracts of animals, including humans as part of normal human intestinal flora but is also sometimes found in the soil, stagnant water, fecal matter, putrified meat and dust. Other habitats of the bacteria include long-term care facilities and hospitals, where this gram-negative bacilli is known to colonize both the skin and oral mucosa of patients and hospital personnel. Infection is primarily spread from these reservoirs. However, Proteus species are not the most common cause of infections and even among the infections caused by the Proteus species of the bacilli, Proteus vulgaris is the cause of a still smaller percentage of infections. For example, the Proteus group of bacteria is the cause of a small percentage of all urinary tract infections (UTI) ; out of these, Proteus mirabilis causes 90% of all Proteus infections and Proteus vulgaris is the cause of even smaller cases of UTI."
Abstract This paper discusses Helicobacter Pylori, a bacterium that causes gastritis of the inner lining of the stomach in humans and is the most common cause of ulcers worldwide. The paper presents a brief history of the discovery of the bacterium and examines the various modes of transmission. Possible methods of diagnosis and treatment are explored.

From the Paper "H. pylori is transmitted from person to person. While the exact mode of transmission is not entirely understood, evidence suggests that contact with infected vomit or stool will increase the risk of developing an infection due to H. pylori. The use of contaminated gastric tubes and the act of belching have been implicated in transferring H. pylori from the gastric cavity to the oral cavity and consequently to a new victim through oral contact. The direct consumption of H. pylori contaminated water, food, gastric contents or fecal matter will significantly increase the risk of developing infection (Perez-Perez, Rothenbacher and Brenner 4)."
Abstract The small Hawaiian squid Euprymna scolopes and the planktonic bacterium Vibrio fischerii are partners in a rather intriguing symbiotic association. The squid harbors the bioluminescent - literally, glowing - bacteria within a small chamber on its underside, providing protection for the squid via a phenomenon known as counter-illumination. This paper provides a general survey of the symbiosis, its mechanisms and its biology and describes ongoing research into the biological system.
From the Paper "The Hawaiian islands and the waters surrounding them teem with the activities of life. Species native to Hawaii's offshore area run a veritable gamut from microscopic plankton- small, free-floating organisms, including some bacterial species- to a wealth of relatively large animal species. Even in such a biologically diverse environment, however, it is fair to say that the small squid Euprymna scolopes is, as the proverbial saying goes, the little fish in a big pond."
Abstract This paper deals with the disease anthrax and the bacterium that causes it. Included is information on history, tests, where it is found, how and who contracts it, symptoms, treatments, and uses as a biological weapon.
From the Paper "Since the events of September 11 shocked our nation we have become increasingly concerned with the possibility of further terrorist attacks. President Bush has already added a new member to his cabinet; Tom Ridge now serves as the Homeland Defense Secretary. Words such as anthrax and biological warfare, which are not usually seen unless you look for them, can now be found almost every time you turn on the television, pick up the newspaper or log-on to the internet. If you had taken a survey of Americans three months ago asking them "What is anthrax"? the most common response next to "I don"t know? would probably have been "Hey, isn"t that a rock band?? Now it can almost be considered a household word. Since September 25th several people in the United States have become infected with a disease called anthrax, some have even died, because of exposure to letters containing a white powder from an, as of yet, unknown mailer. When used as a biological weapon, anthrax posses a serious threat to people and the environment and therefore should not be used as such."
Abstract This paper is an in-depth research paper on the history and development of cloning. The author discusses such topics as procedures and methods, specific experiments, and risks and repercussions of genetic engineering. The paper also includes a discussion of birth defects in cloned animals, stem cell research, and the political and ethical debates concerning genetic engineering.
From the paper:
"Cloning is a form of genetic engineering in which the DNA of a person, animal, plant, or bacterium is used to produce a perfect or near perfect genetic replica of the original. A new individual is created from a single cell. Each group of researchers has its own specific technique. The best known is the Roslin technique, and the most effective and most recently developed technique is the Honolulu technique. The most commonly known are the Roslin Technique, The Honolulu Technique, and nuclear transfer. A technique known as twinning also exists, but it can only be used before an organism's cells split. The cloning of Dolly the sheep is considered by many to be the most important event in cloning history. Dolly was created by the Roslin Technique, which was created by the researchers at the Roslin Institute in Scotland. It spurred public interest in cloning and proved that the cloning of adult animals could be achieved. Until then, it was not known if an adult nucleus was able to produce a completely new animal. Genetic damage was possible, and researchers did not know if the damage would be reversible, but nevertheless, they took the chance."
Abstract This paper covers the history of the epidemic of the bacterium that came to be known as the bubonic plague. It begins in 540 A.D., with the first record of its occurrence, and continues to show its from the Mediterranean throughout Europe and Asia. The plague's spread to England in the 1600s led to the first autopsies being conducted and began the search for a cause and cure to this disease. It has virtually been eliminated in our lifetime with only isolated cases occurring, although, there are now fears that it can be isolated and used as a bio-weapon by terrorists in today's world.
From the Paper "Despite of what is thought, the bubonic plague did not end in medieval times. It has kept killing people all the way until today. The next big outbreak after the one in 1665 was in China in 1894. It then spread west to Bombay, India, and in that the time it took to do that the disease killed millions of people. The next couple of decades after that outbreak, scientists were able to identify and classify the disease and its history. However it could at times be difficult for the scientists because symptoms of the bubonic plague often resembled those of other diseases common in the hot climate of the jungles in India."

Abstract This paper examines the origins of parasites, their relationship to their host and how they have evolved in tandem with many other organisms. The paper seeks to answer several questions including why parasites live where they do and how the origins of evolution affect different parasites, specifically RNA and what role protozoans play in the life of parasites. The paper also discusses the process of Coevolution and the effect that a parasite's long-term residence has on the body of different species, including humans.
From the Paper "However, it is once an organism has taken up residence inside another organism, that a second and crucial process comes into play. This is the process of Coevolution. Coevolution is based relatively simply on the fact that Evolution is a non-stop process. All species are continually changing and developing. Genetic mutations, errors in the copying of DNA and RNA, lead to minute, or even at times, dramatic changes that might be either beneficial or maladaptive. In the normal course of things the maladaptive forms will die out, while the successful adaptations will survive as a result of those organisms that possess them living on to reproduce. The same process of evolution is at work both in host and parasite. As the host itself changes, the environment inside it changes as well. Subtle differences in conditions might mean death a microorganism living inside the body of another animal."
Abstract Legionnaires' disease is defined as a mild to severe pneumonia caused by bacteria. Outbreaks of the condition are the result of exposure to water contaminated with the bacteria and the disease is most commonly contracted by breathing in the bacteria from contaminated water. This paper designs an Organizational Behavioral Management (OBM) program intervention to prevent another breakout of Legionnaire's disease that occurred at a retail store in Virginia in 1996.
From the Paper "In his discussion of OBM, Vecchio (1991) reports that there are five essential steps in any OBM intervention. These are: (1) defining the target behavior; (2) measuring the frequency of the behavior; (3) establishing and communicating behavioral goals (the educative function); (4) monitoring the behavior; and (5) the administration of rewards. It was further noted by Vecchio that rewards (e.g., praise, recognition, bonuses, and so forth) must be directly tied to performance if OBM efforts are to be maximally effective. Thus, the designed intervention included all of the listed steps. Each of these are discussed below."
Abstract This paper discusses leprosy and the evolutionary strategies of the bacterium that increases its ability to reproduce with psychological factors that result in existing cognitive schema from the medieval civilization to present.

The 2001 Anthrax Attacks
From the Paper "Anthrax is caused by the bacterium 'Bacillus anthracis' that is highly lethal in its virulent form. Anthrax most commonly occurs in wild and domestic animals, but it can also occur in humans when they are exposed to infected animals, tissue from infected animals, or high concentrations of anthrax spores. Bacillus anthracis, the bacterium which causes anthrax, is rod-shaped and about 1 by 6 micrometres in size. It was the first bacterium ever to be shown to cause disease by Robert Koch in 1877. The bacteria normally rest in spore form in the soil, and can survive for decades in this state. When ingested by a plant eating animal, the bacteria starts to multiply and eventually kills the animal. They even continue to reproduce in the carcass but eventually revert back to the dormant spore state when they run out of nutrients. ("Bacillus anthracis.")"

From the Paper "Avoiding contact with known diphtheria patients and maintaining a healthy immune system are the most important steps in preventing the disease after vaccination. In the United States, diphtheria is considerably more common among Native Americans and the homeless, suggesting that socioeconomic status, high standard of living and good healthcare play an important role in preventing contraction of the disease."
Abstract This paper explains that, previously considered a benign disabling illness, rheumatoid arthritis is now recognized as a cause of increased mortality due to the systemic effects of peri-cardial disease, interstitial lung disease and systemic vasculitis. The author points out that the differentiation of rheumatoid arthritis from other rheumatic diseases can be difficult; however, certain clinical features, such as joint inflammation and the number and specific joint sites affected can help indicate if the diagnosis should be RA. The paper relates that the etiology of rheumatoid arthritis is still unknown but there is some indication that a common virus or bacterium might serve as a triggering event; however, there is still no evidence to implicate a specific infectious agent.
From the Paper "Joint inflammation is characteristically polyarticular, symmetrical, and in severe cases may be warm and erythematous. Joints involved in Rheumatoid Arthritis include proximal interphalangeal, metacarpophalangeal (MCP), the wrist, elbow, knee, and ankle. Rheumatoid nodules, an aggregate of inflammatory cells surrounding a center of cellular debris, can occur on the extensor surfaces of the elbows or fingers. A poorer prognosis is likely for patients who experienced onset at an early age and who have elevated erythrocyte sedimentation rates and high levels of rheumatoid factor and swelling of more than 20 joints."
Abstract This paper explains the structure, composition and function of viruses and bacteria. The paper also describes a disease caused by a virus and its treatment as well as a virus caused by a bacterium and its treatment. In addition, the paper discusses the development of antibiotic resistance by bacteria.
From the Paper "Viruses are not composed of cells and cannot metabolize or multiply on their own. They consist of either DNA or RNA in from four to thousands of genes surrounded by a protein coat. Sometimes there is an additional coat surrounding the protein. Viruses can be as small as ribosomes or large enough to be seen under a normal light microscope. The genes of a virus can be composed of single-stranded or double-stranded DNA or RNA and the coat can consists of one..."
Abstract This paper answers questions relating to DNA templates and the differences between the structure, function, and the treatment of viruses and bacteria. The paper also explains the necessity for making a template in the replication process.
From the Paper "The DNA has to be replicated so that after cell division each new cell will contain the full amount of DNA material. After replication every new cell will contain one strand of the original DNA plus one strand of the newly synthesized DNA. The original strand acts as template to guide the next process which is the synthesis of a..."
Abstract One of the more challenging problems associated with hospital stays is the nosocomial infections which are caused primarily by staphylococcus aureus. The pathogen appears to be developing specific resistances to the pharmacological weapons developed to date, and the disease continues to represent a threat for many elderly people and those who are already weakened by other physical problems. To determine the cause and potential continuing threat represented by this bacterium, this paper provides a review of the epidemiology of staphylococcus aureus to determine the development of the current body of knowledge about the disease. This is followed by a summary of the research and concludes that this threat will continue and the precautions that need to be taken to try to avoid it.
From the Paper "While the world has never been a sterile place, it would seem that one of the most prevalent and virulent of mankind's microscopic foes has always been Staphylococcus aureus. In fact, staphylococci are ubiquitous, and approximately 30 percent to 50 percent of healthy human beings will be carrying staphylococci at any one time (Eidson, Olson & Sewell, 1997). Staphylococcus aureus is a genus of spherical bacteria of the family Micrococcaceae; the Staphylococcus aureus is universally present in enormous numbers on the mucous membranes and skin of humans and other warm-blooded animals. The umbrella term, "staphylococcus" is popularly used for all the species of the family, and is a reference to the cells' tendency to aggregate in grapelike clusters (Staphylococcus, 2005). Staphylococci are microbiologically characterized as gram-positive (in young cultures), non-spore-forming, nonmotile, facultative anaerobes (e.g., not requiring oxygen); the cells of S. aureus average 1 mm (micrometer; 1 mm = 10-6 meter) in diameter and are usually clustered (Staphylococcus, 2005)."
