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.

  1. 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. 
  2. 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
  3. 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.
  4. 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.
  5. We can use genetically engineered microbes to decompose industrial wastes (oil spills, for example), this process is called bioremediation.
  6. 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.
  7. 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. 
  8. 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
  9. 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 ).
  10. There are present certain bacteria and fungi involved in the production of antibiotics. These antibiotics are used to treat patients with infectious diseases.
  11. 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.
  12. 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.

Career In Microbiology, As you may know, a microbiologist is a scientist who researches tiny organisms known as microorganisms. He or she may need a bachelor’s, master’s, or doctoral diploma in Microbiology.

There are many professional fields inside the science of microbiology. For instance, an individual might specialize within the examine of only one specific class of microorganisms.

A bacteriologist is a scientist who makes a speciality of bacteriology—the examine the construction, features, and actions of microorganisms. Scientists specializing within the subject of psychology examine the varied forms of algae and are known as psychologists.

Protozoologists discover the realm of protozoology, the examine of protozoa and their actions. Those who specialize within the examine of fungi, or mycology, are known as mycologists. 

Virology encompasses the examine of viruses and their results on dwelling cells of every type. Virologists and cell biologists might change into genetic engineers who switch genetic materials (deoxyribonucleic acid or DNA) from one cell sort to a different one. Virologists can also examine prions and viroids, acellular infectious agents which can be even smaller than viruses.

Other professions in microbiology pertain extra to utilized microbiology— that’s, how a data of microbiology may be utilized to totally different elements of society, medication, and trade. Some of those profession fields are briefly described under. The scope of microbiology has broad, far-reaching results on people and their surroundings.
