Importance of Microbiology
Importance of Microbiology, Although they’re very small, microorganisms play very vital roles in our lives. Listed beneath are a number of the various causes to take a microbiology course and to find out about microorganisms.
- It is estimated that our body contains about 100 trillion microbes, which is 10 times of our total number of cells. All these microbes are known as indigenous microflora. Most of them provide benefits to us. They inhibit the growth of pathogens by occupying space, depleting the food supply, and secreting materials (waste products, toxins, antibiotics, etc.) that may prevent or reduce the growth of pathogens.
- Our body contains some opportunistic pathogens, which do not usually cause any infections, they have the potential to cause infections if they gain access to a part of our anatomy where they do not belong. For example, Escherichia coli (E. coli) does not cause us any harm as long as it stays in our intestinal tract but can cause disease if it gains access to our urinary bladder, bloodstream, or a wound
- Microorganisms also produce oxygen which is essential for life on this planet as we know it. For example, algae and cyanobacteria (a group of photosynthetic bacteria) produce oxygen.
- Microorganisms also helped in the decomposition of dead organisms and the waste products of living organisms, they are called decomposers or saprophytes. They release nitrates, phosphates, and other chemicals from the dead organic materials for the growth of plants.
- We can use genetically engineered microbes to decompose industrial wastes (oil spills, for example), this process is called bioremediation.
- Microorganisms also helped in elemental cycles (e.g., carbon, nitrogen, oxygen, sulfur, and phosphorus cycles). There are many bacteria involved in the conversion of ammonia to nitrogen gas. These microbes are important to farmers who practice crop rotation to replenish nutrients in their fields and to gardeners who keep compost pits as a source of natural fertilizer. In microbial ecology, we study those relationships between microbes and the environment.
- Microorganisms play an important role in food chains. Algae and bacteria serve as food for tiny animals. Then, larger animals eat the smaller creatures, and so on.
- Intestinal microbes of animals help in digestion of food and, in some cases, produce substances that are of value to the host animal. For example, E. coli produce vitamins K and B1, which are absorbed and used by the human body
- Microorganisms are also used in the production of various food and beverage industries (Acidophilus milk, bread, butter, buttermilk, chocolate, coffee, cottage cheese, cream, sherry, vodka, whiskey, wine, Acetic acid, acetone, butanol, citric acid, etc ).
- There are present certain bacteria and fungi involved in the production of antibiotics. These antibiotics are used to treat patients with infectious diseases.
- Microbes also play an important role in genetic engineering. In genetic engineering involves the transfer of a gene from one organism (e.g., from a bacterium, a human, an animal, or a plant) to another bacterial or yeast cell. By genetic engineering Bacteria and yeasts gain the capability to produce a variety of useful substances, such as insulin, various types of growth hormones, interferons, and materials for use as vaccines.
- Finally, we come to illnesses. Microorganisms trigger two classes of illnesses: infectious illnesses and microbial intoxications. An infectious illness outcomes when a pathogen colonizes the physique and subsequently causes illness.
A microbial intoxication outcomes when an individual ingests a toxin (a toxic substance) that has been produced by a microorganism. Of the 2 classes, infectious illnesses trigger far extra illnesses and deaths.
Infectious illnesses are the main explanation for loss of life on the earth and the third main explanation for loss of life within the United States (after coronary heart illness and most cancers).
Worldwide, infectious illnesses trigger about 50,000 deaths per day; the vast majority of deaths happen in growing nations. Anyone pursuing a profession in a healthcare occupation should pay attention to infectious illnesses, the pathogens that trigger them, the sources of the pathogens, how these illnesses are transmitted, and the way to guard yourself and your sufferers from these illnesses.
Physicians’ assistants, nurses, dental assistants, laboratory technologists, respiratory therapists, orderlies, nurses’ aides, and all others who’re related with sufferers and affected persons should take precautions to stop the unfolding of pathogens.
Harmful microorganisms could also be transferred from well-being staff to sufferers; from affected person to affected person; from contaminated mechanical gadgets, devices, and syringes to sufferers; from contaminated bedding, garments, dishes, and meals to sufferers; and from sufferers to healthcare staff, hospital guests, and different inclined individuals.
To restrict the unfold of pathogens, sterile, aseptic, and antiseptic methods (mentioned in Chapter 12) are used in all places in hospitals, nursing properties, working rooms, and laboratories.
In addition, the bioterrorist actions of the previous few years serve to remind us that everybody ought to have an understanding of the brokers (pathogens) which might be concerned and learn how to defend ourselves from turning into contamination.

The area of paleomicrobiology includes the examination of historic microbes. Although life is believed to have originated between 3.7 and four billion years in the past, there are not any cellular fossils out there from that interval.
However, there are molecular fossils—molecules (normally lipids) that are identified to be made solely by organisms or, in some circumstances, solely by explicit organisms. Finding such molecular fossils in historic rocks serves as proof that life existed at the moment.
The earliest molecular fossils date again to between 3.7 and four billion years in the past. Some paleomicrobiologists study and examine skeletons and mummified human stays to find out the infectious illnesses that occurred in historic civilizations.
Such research usually involve the restoration of microbial DNA from bone and mummified
tissue samples. For instance, discovering Mycobacterium tuberculosis DNA in Egyptian mummies has revealed that tuberculosis existed way back to 3000 BC. Paleomicrobiology is a superb profession area for people with pursuits in anthropology, archaeology, and microbiology.
Technically, any organism that lives on or in one other residing organism is known as a parasite. It would appear then, that the time period parasite would apply to all of the microorganisms of our indigenous microflora—the viruses and micro organism that stay on or within the human physique.
However, the sphere of parasitology includes solely the next three classes of parasites: parasitic protozoa, helminths (parasitic worms), and arthropods (particularly, sure bugs and arachnids). A parasitologist research these organisms and their life cycles in an try to find the most effective methods to manage and deal with the illnesses that they trigger.
