Hunting Nightmare Bacteria

There are many types of bacteria that can be found in your bathroom. They might also be found on your toothbrush! I have been researching about what bacteria are lurking in my bathroom. I placed 6 petri dishes filled with agar in my bathroom. I left them there for 24 hours to collect bacteria samples.

In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.

Unknown bacteria determined to be Alcaligenes faecalis because of its morphological, physiological and metabolic properties.

The objective of the investigation was to perform multiple experiments that would lead to the identification of an unknown bacteria. This bacteria was causing a urinary tract infection on a patient. A sample of the bacteria causing the infection was received and analyzed. The first step was to isolate the bacteria to insure that sample was free of contamination. A MAC plate, a PEA plate, along with a Nutrient agar plate where used to produce pure colonies by using the quadrant streak method on each plate. After a 24 hour incubation period the colonies where isolated. The bacteria collected was inoculated into slants, nutrient broth for cultivation. A sample from the MAC plate and the PEA plate were collected and gram

A couple times a year local and national mass media put the spotlight on problems connected to antibiotic overuse. Some people consider those problems to be real and serious, and others think that the discussed topics are nothing more than new “fashionable” subjects to talk about, distracting people from “real” problems, such as climbing gas prices or war expenses. Meanwhile, antibiotic overuse continues as a common practice among US doctors and agribusinesses for the last 20 years. The practice of antibiotic overuse has put patient’s health at risk, contributed to antibiotic resistance and increased bacterial mutation to a new, stronger level; as well as it hitting the economy with new costly expenses in health care. It is time to stop

Throughout my life, adults have insisted the use of antibiotics to fight against the most inconsequential illnesses, whether it’s the cold or the flu. However, neither illness is due to invasion of bacteria. This misuse can lead to antibiotic resistance, also known as antimicrobial resistance(AMR), currently one of the central issues facing the public health system. While the process for antibiotic resistance occurs naturally through the process of adaptation, the mismanagement of antibiotic resources has accelerated the rate at which the bacteria adapt. The occurrence of this misinformation isn’t limited to a few adults: even some of my peers suggest taking antibiotics when faced with the flu. This leads to asking whether AMR is truly a problem and are present regulations enough to combat the issue.

As the flowchart shows, a series of tests were conducted to identify the unknown bacterium #65. Microscopic observation of the gram stain indicated a gram-positive coccus bacterium. S. epidermidis was used as the gram-positive control while E. coli was used as the gram-negative control. This observation led to the elimination of all gram negative and rod-shaped genera: Enterobacter, Citrobacter, Klebsiella, Escherichia, Pseudomonas, Serratia, Alcaligenes, Neisseria, Proteus, Salmonella, Shigella, Erwinia, Veillonella, Flavobacterium, Bacillus, Arthrobacter, Lactobacillus, Listeria and Kurthia (2). By performing the catalase test, it was determined that the bacterium was catalase negative and it did not produce bubbles. M. luteus and E. faecalis were used as positive and negative controls, respectively.

The purpose of this lab was to identify an unknown microorganism using lab techniques. The importance of identifying microorganisms is essential to the survival of humans, expansion of modern day medicine and improvement of quality of life. In 1884, Hans Christian Gram designed a differential staining technique to identify bacteria that would change the future of microbiology. He give rise to a staining process, known as the Gram stain to differentiate microorganisms into two groups between positive and negative gram staining microorganisms. The Gram stain is essential in a lab technique as it distinguishes the cells based on the physical properties of the individual cell walls, and is almost always the first test preformed to differentiate a microorganism. The identification of weather a microorganism is gram positive or negative can revel the bacteria’s virulence, cell wall structure, resistance to antibiotics, resistance to physical disruptions and so much more. In order to identify the unknown provided, unknown #27, the Gram stain was the first test preformed. After discovering that the unknown bacterium was indefinitely a gram positive microorganism, the vast possibilities were narrowed down. However, In order to more definitively identify the unknown, the next step was to preform biochemical tests. A biochemical test identifies metabolic

A Superbug is a bacterium that can live in the human body and has the ability to withstand all forms of antibiotic medication. Superbugs are becoming increasingly significant in modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus, 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been widely used and abused, people began to treat everything with this ‘miracle’ drug. If antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will fall back into an era without the readily

we may be overridden by diseases that are not easily treated by just popping a couple of pills.

At least two million people are infected with antibiotic resistant superbugs and at least 23,000 die from them.

The problem is that antibiotics resistance has become a very big problem in todays society. Antibiotics are no longer effective against certain super-bugs such as MRSA.

As a writer for The Globe and Mail, Jennifer Yang, stated, “Anti-bacterial products containing anti-microbial agents are being increasingly marketed to Canadians for personal and household use despite a lack of evidence for additional benefit and serious concerns about the potential for increased bacterial resistance.” The concern she is talking about is centred in the use of the products such as disinfectant sprays, of which can kill 99.9% of bacteria on a given surface. The 0.1% that is left remaining is the mutated antibiotic-resistant super bug which the disinfectant is unable to kill due to its mutated nature. And being the only type left, it has no competitors remaining for resources and can divide at a rapid pace, giving birth to a larger colony of highly dangerous pathogens. The same phenomena occurs when patients stop taking antibiotics half way through their treatment. The amount of bacteria in their body at that point has a higher percentage of stronger bacteria than the weaker. Therefore, when the patient decides to stop their antibiotic treatment, they inadvertently create more resistant bacteria than there originally was in their body, as the mutated bacteria now has more room to grow. If those bacteria are then passed on to another person, the rate of resistant bacteria dramatically increases, raising the amount of near invincible pathogens in the world by another percentage.

The overuse of antibiotics has been a problem for well over a decade. This misuse leads to many nonvisible problems arising within the human population. As the use of antibiotics increases, the number of antibiotic resistant bacteria also increases. When bacteria become resistant to an antibiotic, another antibiotic must be used to try and kill it and the cycle becomes vicious. Michael Martin, Sapna Thottathil, and Thomas Newman stated that antimicrobial resistance is, “an increasingly serious threat to global public health that requires action across all government sectors and society” (2409).

The overuse of antibiotics is creating stronger germs; some bacteria is already resistant to antibiotics. Therefore, when bacteria become resistant to antibiotics, it is difficult and costly to treat that infection. The treat to a serious bacterial infection is a big threat to public health.
