Importance Of Microbiology

For many years the identification of microorganisms has been important in the world of medicine. It is essential or correct disease diagnosis in patients and for proper treatment. Knowing the correct identity and characteristics of microorganism is crucial when disease outbreaks occur in populations, also knowing how humans can benefit from microorganisms is important; many can be used in making certain foods or antibiotics.

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.

There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient, so as to know how it can be treated, to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that I have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium.

The pandemic struck the world and infected 1/3 of earth’s human population, killing over 50 million humans. The world’s top doctors have never witnessed anything of this killing magnitude besides the bubonic plague of 1348 but the transmissibility is of nothing they’ve ever seen in their lifetime or of recorded history. People abruptly became aware of the importance of health, and need of medicine and cleanliness.

-The germ theory led to the creation of vaccines, anti-toxins, antibiotics, and the development of laboratory-based pharmacology to help patients to get healthy.

Infectious epidemics and pandemics have happened all through mankind's history. “They remain the prime cause of death worldwide and will not be conquered during our lifetimes.” The flu of 1918 was one of the deadliest epidemics in history. “It infected an estimated 500 million people worldwide–about one-third of the planet’s population at the time–and killed an estimated 20 million to 50 million victims. More than 25 percent of the U.S. population became sick, and some 675,000 Americans died during the pandemic.” No one knew how the virus spread, there were no antibiotics to fight it, and no flu shots to prevent it. In the final year of World War I, it struck terror in the hearts of people all across Europe and left more death in its wake than the combined military actions of the combatants. “It killed more Americans in a few months than World War I, World War II, the Korean War, and the

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.

The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also, knowledge of different bacteria helped others make antibiotics that are used today.

Being able to figure out an unknown culture or bacteria is very important and a great knowledge to have. It helps people every day from finding cures to bacterial infections, discovering new kinds or simply just knowing the limits of what they are capable of. It allows scientist to know how to kill them treat then and ect. along with determining if they are harmful or benefit humans, and plants Along with being able to identify different species of

Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.

Based on research and observation, we now know that infectious diseases are caused by microorganisms (pathogens) and that the immune system provides defense against infectious diseases.

Chapter 12 caught my attention because it informs you how infections develop into humans and types of agents to stop the infection. Infection and pathogens are created by microorganisms that enter the body. Microorganisms that can cause this are bacteria, viruses, fungi and parasites. These microorganisms can enter through your nose, mouth or skin so it is recommended to always wash your hands and receive vaccinations. Antibiotics are not as effective like it was back in the days, because microorganisms learned to be resistant to it. There is antibacterial, antiviral and antituberculosis agents to control microorganisms. Antibacterial agents destroys microbes and prevent it from multiplying. Antituberculosis are agents that treat diseases that

Throughout history until the 19th century, infectious diseases, epidemics, and pandemics were thought to be the manifestation of supernatural forces and little to nothing was truly effective in preventing or treating these devastating threats to society. It was only during the Age of Reason and the Enlightenment that the long-accepted realities of society were questioned and research was conducted based on science and reason that would forever change the world we live in (Kumar, 2007). The science of epidemiology was founded by John Snow’s identification of polluted public water well as the source of an 1854 cholera outbreak in London. Shortly thereafter germ theory began to emerge and science took off.

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.

Health care professionals within conventional medicine believe that diseases are caused by microorganisms such as bacteria and viruses.
