What is a Microbiology?

Microbiology is the study of microorganisms, which are organisms that are too small to be seen with the naked eye. Microorganisms include bacteria, viruses, fungi, 
algae, and protozoa. Microbiology is a broad field that encompasses many different subdisciplines, including virology, bacteriology, mycology, and parasitology.
Microbiologists study the growth, physiology, genetics, biochemistry and ecology of microorganisms, they also study the interactions between microorganisms 
and their environment, including other microorganisms and host organisms. They also study how microorganisms can be used in various industries such as food and beverage, agriculture, biotechnology and medicine.
Microbiology has many practical applications in areas such as medicine, where it is used to diagnose and treat infectious diseases, and in the food and 
agricultural industries, where it is used to ensure food safety and improve crop yields. Microbiology also plays a critical role in the development of new treatments and vaccines for a wide range of diseases caused by microorganisms.
