Bacteria Friend or Foe?

Bacterial and fungi infections are easy to cure with the use of antibiotics, where as viruses can be hard to cure or vaccinate against, such as the common cold. Bacteria can be found everywhere and anywhere Soil, Water, Plants, Animals, material and even deep in the earth's crust. Bacteria feed themselves by making there food with the use of sunlight and water. We would not be able to live without Bacteria. The human body consists of lots of friendly bacteria which also protect us from dangerous ones by occupying places in the body. Some of the most deadly diseases and devastating epidemics in human history have

Bacteria can exist almost everywhere, some are harmless, and some are harmful. There are thousands of different types of bacteria and they fall

2. Breaks in the skin. One of the many functions of the skin is to act as a barrier against infection. Anything that penetrates the skin, or for that matter the mucous membrane that lines the mouth or nose, provides a route for infection to enter. Typically, bites, scratches, puncture wounds by needles etc increase the risk of infection.

It 's bad or infectious bacteria that cause illness as they rapidly reproduce and produce a toxin that kills or mutates cells, bacteria is also self sufficient.

It’s fascinating and a bit strange to think just how many bacteria live in our mouths, on our skin, and inside our bodies. Usually we think of all bacteria as being bad and harmful to us, but our bodies contain tons of good bacteria that play a very important

Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.

Microorganisms must either attach to, or penetrate one of bodies surfaces. The site through which a microorganism enters the body is called the route of entry. The skin acts as a protective barrier, in order to cause infection the microorganism must break through the protective barrier. they either do this through a natural opening such as the mouth ,nose, ears, eyes, urethra, rectum or vagina, or enter through a unnatural break in the skins surface such as cuts and grazes, bites or scratches. They can also occur through a surgical wound caused by a operation. Also conditions such as psoriasis or eczema cause breaks in the skin which microorganisms can enter.

Throughout history, infectious diseases have impacted communities around the world. Outbreaks of bacteria and viruses in the past have damaged cities and devastated populations. Over the years, new developments in technology have led to advances in medicine and health. The great strides that have been made over the years have helped improve the lives of individuals and have led to a better environment.

Bacteria are a very small, self-sufficient, one-celled organism that thrives in a variety of environments. However, many bacteria thrive in the mild 98.6 health body environment, some of these environmentally content bacteria in your body are actually good for you; its only 1% that isn’t.

Microbes are everywhere and anywhere. Microbes can be found from on surfaces of our daily lives to microbes we encounter and spread on. Microbes have been always since life started in this planet. According to a BBC article about Earth, “…an older microbe came to light…to be a remarkable 3.5 million years” (BBC). As stated, microbes may be considered to have been here long before any other living organism, which means these microbes have evolved through time as well. With evolving comes the different types of bacteria that may benefit us and also harm us. Harmful bacteria such as Lyme disease and the Plague which both derive from an infected insect with different bacterium. These two different disease made different approaches to our history

The most common cause of Gingivitis is poor oral hygiene (Mayo Clinic. 2017). The gums are attached to the teeth at a lower point of the gums edge that cannot be seen. This forms a space called a sulcus. When food gets trapped in this space an infection or Gingivitis may occur. Infections can occur from plaque build up. Plaque is known as a thin film of bacteria that constantly forms on the teeth. When plaque advances, it will harden and become tartar. Which can then develop an infection when the plaque

Each and every human mouth contains microorganisms, good and bad. It has been concluded that there are up to 1,000 variety of microorganisms residing in the oral cavity. Many of these bacteria are harmless to humans and are natural to the body. However, there are several that can cause decay and chronic infection in the oral cavity, which are also known as gram negative bacteria (Gehrig & Willmann, 2016). Biofilm, also known as plaque that forms on teeth, contains an organized matrix of microorganisms, which consists of these gram negative bacteria that can cause periodontitis. There are several types of biofilm in nature, but plaque in the oral cavity can be very destructive to a human’s periodontium and can place other organ systems at risk for harm. Bacteria reproduce very quickly and form huge colonies quickly as well (Gehrig & Willmann, 2016). It is important for women, who are pregnant or whom are trying to become pregnant, to have a thorough periodontal exam,

Miasma, or “bad air,” is once thought to cause cholera during the cholera epidemic of the 19th century (Cholera epidemics in the 19th century, n.d.). Epidemiologist John Snow disproved the widely popular miasma belief and cholera is now understood to be an infectious disease caused by the bacterium Vibrio cholerae (Tuthil, 2003). V. cholerae is a Gram-negative, monotrichous bacillus bacterium. Epidemic cholera can only be caused by two serogroups, serogroups O1 and serogroup O139 Vibrio cholerae (Finkelstein, 1996). Cholera is transmitted by the fecal-oral route through the ingestion of food or water contaminated with V. cholerae. Advanced water and sewage treatments have eliminated the spread of cholera in industrialized countries such as the United States.

The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the
