Pathogenic bacteria Essays

few organisms are pathogenic to human beings. They may be a bacteria, virus, fungus or a parasite. Many of the bacteria are a part of the normal body flora and inhabit various areas in the body such as the oral cavity, nose, skin, nasopharynx, oropharynx, gastrointestinal tract, genitalia, urethra, vagina as well as the external ear. These organisms most of the time are non pathogenic, but in some cases especially in immunosuppressed patients, they may cause diseases. Bacteria that can cause infection

Contamination with pathogenic bacteria from the human/animal reservoir can occur when the landing place is unhygienic or when the fish are washed with contaminated water. Upon the processing of fish, its exposure to water is a critical part as pathogens may be present in the water used which can cause contamination and spoilage (Shoolongela & Schneider, 2012). Contamination of food can occur because of problems in food production, preparation, storage or cooking. The aquatic environment and soft

Activity of Three Medicinal Plant Extracts from Duba Province Tabuk, Saudi Arabia on some Human Pathogenic Bacteria Abstract: Three seed extracts of coffee (Coffea arabica), black cumin (Nigella sativa), and date palm (Phoenix dactylifera) plants were purchased from local market in Duba province, west Saudi Arabia were assayed for the in vitro antibacterial activity against three human pathogenic bacteria viz Klebsiella pneumoniae, Psuedomonas sp, and Escherichia coli using hole plate diffusion method

The presence of bacteria and pathogenic organisms is a concern when considering the safety of drinking water. Pathogenic organisms can cause intestinal infections, dysentery, hepatitis, typhoid fever, cholera, and other illnesses. Sources of Bacteria in Drinking Water: The Need for Water Testing Human and animal wastes are a primary source of bacteria in water. These sources of bacterial contamination include runoff from feedlots, pastures, dog runs, and other land areas where animal wastes are deposited

Antibiotic medications have saved many people’s lives. Unfortunately antibiotics are no longer as effective in stopping pathogenic bacteria infection. Currently there is an antibiotic resistance crisis since may bacteria have become or are becoming resistant to all of the antibiotics developed. Instead of researching new antibiotics, which will continue to promote antibiotic resistance, antibiotic stewardship should be promoted specifically dealing with preventing infections, monitoring antibiotic

The attachment of E.coli on the surfaces of epithelial cells pertaining to urinary tract is achieved throughout several bacterial adhesive proteins. In parallel with biofilm formation of pathogenic E.coli on animate and inanimate surfaces, the secretion of exopolysaccharide occurs. The most important VFs which are found in UPEC strains are recognized as capsule, fimbriae, pili, flagella, lipopolysaccharide (LPS), hemolysins, siderophores and

1.Describe three conditions that create opportunities for pathogens to become harmful in a human. There are many conditions that create opportunities for pathogens to be harmful for humans. The first is when the immunity has already been compromised by an infection. In cases like this, there is the chance of other pathogens to cause opportunistic infections in such host. Another condition is if the human host does not keep proper personal and environmental hygiene. Many pathogens thrive in dirty

Bacterial diseases is any type of disease caused by bacteria. Bacteria 's are a kind of microorganism, which are tiny forms of life that cannot see by easy only be seen with a microscope. The bacteria that cause disease are called pathogenic bacteria. Bacterial diseases happen when pathogenic bacteria inter the body and begin to reproduce and grow in tissues. Pathogenic bacteria may also emit toxins that damage the body. Common pathogenic bacteria and the types of bacterial diseases they cause include:

Escherichia coli bacteria with the help of a plasmid. Escherichia coli bacteria also known as E. coli, is a bacterium that is rod shaped and contains flagella to help it move. The bacterial DNA is circular inside of an E. coli bacterium. E coli. is most known for being found in the intestine of humans and animals but it can also be found in other places such as food

Bacillus subtilis is a gram-positive rod-shaped bacteria that is often found in the soil and on various plant materials (Sietske de Boer and Diderichsen 1991). B. subtilis bacteria are seen as being non-pathogenic and safe toward human consumption, however, often times the bacteria are associated with another strain of microorganisms that have the ability to infect humans who have been exposed to immunosuppressive drugs (Sietske de Boer and Diderichsen 1991). Furthermore, B. subtilis has been found

Bacterial growth is a good example of exponential growth. Bacteria are everywhere, inhabiting the surfaces of almost all tangible things. Here’s a quote from http://microbemagic.ucc.ie/about_microbes/“There are both harmful and helpful bacteria, some of which clean us and some of which kill us” Knowing about their ability to grow and divide has proven useful to us, as we can try to contain harmful bacteria, or figure out how fast it’ll spread. Bacteria have been on earth since ancient times, and clearly

greater number of bacteria. We used three jars of Activia yogurt to perform this experiment. We placed the yogurt in different temperature for different time. One yogurt placed inside refrigerator, we used this yogurt for control variable, the second one left at room temperature for 24 hours, and the third one left at room temperature for 6 hours. The results showed a higher amount of bacteria growth in the yogurt

Bacteria are a part of the many prokaryotes of this world and can be found anywhere and can thrive in various environments. There are good and bad bacteria in our body such as in our GI tracts and our immune system. Bad bacteria on the other hand can be pathogenic and dangerous to us humans. These are called diseases and they can severely be life threatening in many situations. There are many forms of bacteria and they can be classified in many ways. For example, by their composition, whether they

Introduction Probiotic are small single celled living organisms either bacteria or yeast that are ingested to benefit health and help fight disease. A wide variety of different probiotics exists, but most are bacteria of the lactobacillus, Bifidobacterium enterococcus, or exherichin genera or are yeast of the genus saccharomyces (Willey et.al 2011). This practical will aid in determining where the commercial probiotics used by human contain live or viable cultures. Methods and materials A probiotic

respiratory symptoms to pneumonia. A single death has been reported out of the 70 known cases. I believe the workers had been exposed to Legionella which is a pathogenic, Gram-negative bacteria. This bacteria is naturally found in fresh water, and thrives in warm bodies of water, its ideal growth temperature is 90 to 108 F. Exposure to this bacteria would cause one of two types of diseases the first would be Pontiac fever or Legionellosis. Pontiac fever is a milder version of the infections, symptoms

Risk factors It has been recognized that the progression of periodontal disease, its severity, and its response to treatment varies from patient to patient. Bacteria are important for disease but insufficient by themselves to cause the disease. It is the patient’s risk factors, and the host susceptibility that determine probability to the disease. Risk factors are patient characteristics associated with the development of disease. There are a number of acquired and environmental risk factors that

Interested in studying infectious diseases, which is the microorganisms [1]. There are four type of microorganisms that causes infectious disease are bacteria, parasites, fungi and viruses. The microbiology laboratory is study the microorganism that cannot be seen by the eyes [2]. The microbiology laboratory is take a sample from patient to know what type of bacteria or another microorganism a causing the disease, and what the best treatment for it. The main purpose of the microbiology laboratory is work to

microwave affect how much bacteria is killed in ground beef?” and “Is there a way to predict how much bacteria will be killed at any level of power that is divisible by 10?”. Each power level on a microwave has certain functions. For example, 10% is for softening foods like butter or chocolate, 50% is for slow cooking, and 100% is for regular cooking or boiling. As the power level increases, the temperature level increases with it. High temperatures have been proven to kill bacteria, so every 10% increase

that would help lead to the unknown plus how it can impact with the environment around us. Following the tests and flow chart, #29 the organism that was given is Enterobacter cloacae. E. cloacae is a Gram-negative bacillus, rod-shaped, that is a pathogenic (1). Enterobacter is originally a genus that is motile. E. cloacae is most commonly found scattered and spread in the

Therefore, the treatment of E.coli infections is increasingly becoming difficult. It is necessary to know the antibiotic susceptibility pattern of pathogenic E.coli to select the correct antibiotic(s) for the proper treatment of the infections. (5) E.coli is a Gram negative, motile, nonsporing, lactose fermenting bacillus. The ability of E.coli to cause extraintestinal infections depends largely on several
