As a university biology teacher, I have always been passionate about teaching each and every one of my students about various aspects of microbiology. The study of microbiology entails that the learner is able to evaluate the science of basic microbiology and then be able to understand its fundamental aspects accordingly.
The student should know that the science of microbiology focuses on the study of minuscule organisms by using a variety of tools. Human life has many uses for microbes aside from the organisms being able to cause human diseases, and this makes microbiology imperative. It is also to be acknowledged that individual microbes and their numbers in and on the planet are unbelievable in proportion.
Germs or microscopic organisms are defined as either single-celled (unicellular) or cell clustered (acellular) organisms. Included among them are fungi, protists, and other eukaryotes, as well as prokaryotes. Although not strictly classified as living organisms, prions and viruses are also studied in microbiology.
Microbiology also includes immunology or the study of the immune system because of how immune systems interact with pathogenic microscopic organisms. This is why we often find microbiology and immunology intersecting with each other. This is also the reason why we have paired degrees such as Microbiology and Immunology offered as a course in many colleges.
A broad term encompassing parasitology, mycology, virology, immunology, bacteriology and other branches, microbiology studies those related topics and observes microbiological procedures that need to be aseptic and that utilize different tools, which include light microscopes as well as a variety of stains and dyes and their combinations.
Microbes are present in the food we eat, the air we breathe and in many other aspects of human life, and this makes the study of microbes of high importance in the society we live in. With microbiological research continuously expanding, there will surely be a greater demand for skilled microbiologists as the years go by.
According to conservative estimates, only 1 percent of the microbes present in a particular environmental sample can be cultivated, making it impossible to determine the exact number of bacterial species and cells on the planet. Recent estimates of this effect peg the actual quantity to be at 530 (five to the power of thirty), which is considered quite high.
Despite the fact that microbes were observed directly more than three centuries ago, the exact quantitation, description, and determination of their functions are still beyond being complete, considering the tremendous diversity that has been disclosed by culture-free and genetic means.
It is critical for learners of microbiology to understand the Germ Theory of Disease thanks to the work of Louis Pasteur. It is also vital that microbiology students become extremely adept at using the microscope, for it is the one single instrument they will be handling the most in the study of microorganisms.
