Microorganisms And Bad Bacteria

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

Modern-day advances have allowed scientists to develop methods to control pathogens. The more common methods include the use of antiseptics, antibiotics, and vaccines. By definition, antiseptics are chemicals used to kill pathogens. A few widespread antiseptics include soap, vinegar, and rubbing alcohol. Antiseptics are primarily used for the external destruction of pathogens, while antibiotics and vaccines target internal pathogens. Nevertheless, there are and can be difficulties concerning the use of antibiotics. “As antibiotic use has become more common, antibiotic-resistant bacteria have evolved.” This resistance due to evolution is called antibiotic resistance. It results in the antibiotics having no effect whatsoever on the bacteria, rendering the antibiotics useless. When antibiotic resistance occurs, scientists must resume their search to create a new medicine to can kill the mutant bacteria.

In this experiment, we were given a sample of an unknown bacterium and asked to classify it based on its physical and metabolic properties. We hypothesized that the unknown organism was Alcaligenes faecalis, a motile Gram-negative bacillus that resides in water, soil, blood, urine, and feces (Herrera n.p.) It was first isolated in 1896 by Petruschky, who

Bacteria - are micro-organisms that consist of only one cell. Bacteria multiply by splitting themselves in two, which is called a binary fission. Because of this they can increase in number rapidly. The majority are harmless, but some can be pathogenic which results in bacterial infection occuring. Bacterial infections can be treated by using antibiotics. Bacteria can evolve a resistance to antibiotic e.g. MRSA. Some diseases caused by bacteria include tuberculosis, pneumonia, salmonella, tetanus and syphilis.

Most people naturally carry the bacteria in their intestines, away from the oxygen that would kill them. Given that our intestines produce different types of bacteria, so if we take antibiotic

Certain people work well at high altitudes. People who live at higher altitudes have a higher hemoglobin count since it helps blood cells deliver oxygen to nourish body tissues. The oxygen level in the atmosphere decreases as the altitude increases. This is true with the majority of people who live in these high altitude regions like the Andes. There is a group of people from Tibet who does not follow this trend. They have a much lower hemoglobin level than an average person, and they live and work as successfully as other groups. Scientists questioned why did the Tibetans have a lower hemoglobin count that allows them to live and work successfully? The discovery of the mutation in the EPAS1 gene may have an answer.

The video “Program Four: Creators of the Future” talks about microbes in general; especially how some of them are resistant to antibiotics in various circumstances. Microbes are all around the world, even inside us. Many microbes are beneficial to humans but some of them are not. They are mostly associated with illness and because of that, in 1928 Alexander Fleming invented penicillin, which is an antibiotic produced by mold. Penicillin was the first microbial product to kill human diseases. Some microbes are resistant to all antibiotics and cannot be treated. When penicillin functions correctly, it kills the bacteria by destroying their cell walls. Microbes reproduce by replicating themselves in two; when a mutation in the replication occurs, what happens is that the microbe with the mutation is going to be resistant to all antibiotics known for the moment. Nothing will stop microbes from mutating;

This book mentions the importance of microbes in human health that was written by Dr. Martin Blaser through his professional and personal experiences. Dr. Blaser is a director of the New York University Human Microbe Program, and he constructs a case about the importance of microorganism inside of our body. Blaser’s interesting commentary on medicines such as antibiotics, or any antimicrobial drug jeopardizes the way people are using now. There are 16 chapters that Blaser will be revealing about the dangers of overusing antibiotic drugs.

When bacteria are thought of, germs and sickness come to mind. Bacteria is the stuff that you don’t want to encounter because it will make you sick. Many times, this an accurate assumption. There is Escherichia coli; these gram-negative bacteria cause diarrheas and can sometimes cause urinary tract infections pneumonia. They can be difficult to treat due to drug resistance. (Center for Disease Control, 2017) There are gram positive bacteria such as Staphylococcus aureus (S. aureus or “staph”) Staph as its commonly called can cause skin infections like boils and cellulitis. Most staph infections are not life threatening but they can become so in the form of sepsis, pneumonia and osteomyelitis (Minnesota Department of Health Fact Sheet, 2010) There are food borne bacteria such as Clostridium botulinum are anaerobic, rod shaped bacteria that causes the disease botulism. Botulism is a life-threatening disease that affects the nervous system it is commonly associated with improperly done home canning. (WHO, 2016) While there is no argument that there are many bacteria that we as humans would do will to stay away from it is also true that we need microorganisms in our lives. From disposing of bacteria in waste water to vaccines to the food we eat we rely on bacteria to keep us healthy.

Antibiotics are a powerful medication that fights bacterial infection. Antibiotics can save lives. Antibiotics specifically treat infections caused by bacteria, such as Staph., Strep., or E. coli., and either kill the bacteria or keep it from reproducing and growing (2016, L. Anderson, PharmD). Your body's natural defenses can usually take it from there. Antibiotics are specific for the type of bacteria being treated and in general, cannot be interchanged from one infection to other. Antibiotics are not the correct choice for all infection. Antibiotics can not fight infection caused by viruses such as cold, flu, coughs, sore throats, or acute sinusitis. Antibiotic penicillin in the 1920s made a big impact on human history. Not only did it lead

Antibiotics are known to be used for fighting off bacteria oriented diseases. “Antibiotics work by blocking vital processes in bacteria, killing the bacteria, or stopping them from multiplying.” (NPS). There is two categories for antibiotics: broad-spectrum and narrow-spectrum. Broad-spectrum antibiotics such as amoxycillin and gentamicin are drugs that are used

Bacterial Pathogens have been developing resistance to antibiotic treatment soon after these drugs were developed. Mutations in the genes of the bacteria allow it to survive despite being exposed to the medications designed to kill them. Through directional selection, the bell curve is shifted to a phenotype that is designed to survive in harsh conditions that would normally kill them.

Abstract: Background research states that bacteria are microscopic single-celled organisms that are ALL AROUND the environment. We can stop the spread of germs by coughing/sneezing into a tissue. Throw it out right away after that. If you don’t have a tissue, cover your cough/sneeze. Always wash hands after sneezing/coughing, or after throwing away used tissues/handkerchiefs. Diarrheal diseases, meningitis, pneumonia, sinusitis, skin diseases, tuberculosis, urinary tract infections, common cold, & vaginal infections are caused by bacteria. Bacterial growth refers to an increase cell number. Bacteria divide & grow by binary fission. To make your immune system strong, you have

Only a few decades ago antibiotics was a wonder drug that could cure even the most deadly diseases. Presently, numerous antibiotics have become less effective or potent to against the bacterial infections. This is due to the high effectiveness and how frequently they were used to treat diseases. Serious infections have become resistant to the commonly used antibiotics have caused a major global healthcare concern for not only the present, but also the future. These bacterial infections require more serious and long term treatments, meaning they are usually more expensive and difficult to treat. The “post-antibiotic era” is significant issue that is affecting the way doctors treat bacterial infections, furthermore the steps to slow the process

Antibiotic medicines treat infections caused by a type of germ called bacteria. They work by hurting or killing the bacteria that make you sick.
