Study Notes

Introduction to Microbiology and Parasitology

Microbiology is the study of living things that are too small to be seen without magnification.
Derived from three Greek words: Micros (small), Bios (life), and Logos (science or study).

Definitions

Microbiology is a specialized area of biology that deals with living organisms that are too small to be seen without magnification.
Parasitology is the study of organisms (parasites) that take their abode and depend on a bigger organism (host) for nourishment and shelter.

Microorganisms

Microorganisms are microscopic organisms that are dominant on earth and include bacteria, protozoa, microscopic algae, and fungi.
They are the oldest organisms on earth.

Categories of Microbes

No specific categories mentioned in the text.

Divisions of Microbiology

Helminthology: the study of worms.

Branches of Microbiology

Medical Microbiology: the study of pathogens, the diseases they cause, and the body's defenses against disease.
Public Health Microbiology and Epidemiology: monitors and controls the spread of disease in communities.
Immunology: the study of the complex web of immune responses to infection by microorganisms.
Environmental Microbiology/Microbial Ecology: the study of microbes in their natural habitats.
Industrial/Applied Microbiology: the study of the practical uses of microbes in food processing, industrial production, and biotechnology.
Sanitary Microbiology: the processing and disposal of garbage and sewage wastes, and purification and processing of water supplies.
Biotechnology: includes any processes in which humans use the metabolism of living things to arrive at a desired product.
Agricultural Microbiology: involved with the relationships between microbes and crops, with an emphasis on improving yields and combating plant diseases.
Food Microbiology: the study of microorganisms that inhabit, create, or contaminate food.
Veterinary Microbiology: the study of the role of microbes in veterinary medicine or animal taxonomy.
Microbial Physiology and Genetics: the study of microbial growth, metabolism, and cell structure.
Genetic Engineering and Recombinant DNA Technology: involves techniques that deliberately alter the genetic makeup of organisms.

Significance and Practical Applications of Microbiology

Presence of indigenous microflora.
Knowledge of opportunistic pathogens.
Essential for life, decomposition of dead organisms and waste products of living organisms.
Bioremediation: decomposing industrial waste.
Elemental cycles: carbon, nitrogen, oxygen, sulfur, and phosphorus.
Food for tiny animals.
Escherichia coli aids in digestion.
Essential in various food and beverage industries, producing enzymes and antibiotics.
Essential in genetic engineering, using bacteria and yeast to produce insulin, growth hormone, interferons, and materials for vaccines.
Microbes used as "cell models" for knowledge of disease causation.
Knowledge of disease causation: infectious disease and microbial intoxication.

Relevance to Nursing and Other Health Professions

"Know thy enemies" to prevent spreading of pathogens.
Advantage in seeing specific vulnerabilities.
