Microbiology is the field of scientific study that deals with microorganisms, be it unicellular or multicellular. Traditionally microbiologists relied on techniques such as staining, decay and so on before moving on to microscopy. Microbiology has numerous sub-disciplines like mycology, immunology, bacteriology, etc. Due to the peculiar nature and unknown nature of microorganisms, microbiology is growing tremendously all over the world. Microbiologists are in the constant search for various new microorganisms, their study, and even in the development of various methods and devices that would further the detection and study of them. This field of medicine is witnessing various developments and advancements in technology like diagnostic methods such as immunoassays, automated and semi-automated systems, and even biological systems such as polymerase inhibitors. 

The course is the discipline in which the two other disciplines of chemistry and biology are combined so as investigate living systems and the relationship they have with the environment, along with the studies of microorganisms and the effect they have on humans. Microbiologists are required to have a deep understanding of many disciplines of science as well as many other aspects that affect human life as they are present everywhere, they play key roles in important life systems such as nutrient cycling, biodegradation/biodeterioration, climate change, food spoilage, disease control and prevention, and biotechnology. Due to their possible diversity and number, microbes are incorporated into the working many systems such as the production of life-saving drugs, the manufacture of biofuels, cleaning up pollution, and producing/processing food and drink. The course follows a structured and detailed process of learning by understanding topics such as bioenergetics, bio instrumentation, food and dairy microbiology, virology, molecular immunology, microbial physiology, microbial genetics, fermentation technology, and pharmaceutical microbiology. These courses are vital as microbiologists usually work in hospitals as pathological cytological laboratory technicians, where they can help the pharmaceutical industry and work as their research and development division. They are also needed in the agricultural sector where they are recruited to research various forms of seeding and fertilization procedures, they also need to build skills to handle industrially produces organisms and conduct cultures on various aspects including preservation and further the maintenance of various microbiological operations involved in bacterial and fungal fermentations from Lab-scale to Industrial-scale point of view.

There are several courses offered in the field of microbiology. The Diploma in Microbiology is a postgraduate certification that ranges from around one year to three years duration. The universities offering these courses usually ask the students to go through an entrance examination test. Candidates who have completed their Bachelor’s courses under a registered university in the fields in combination with microbiology are also considered eligible for the same. After the completion of the course, a microbiologist can work in the industry as a bacteriologist where they will be responsible for studying the behavior of bacteria, including positive and negative contributions. The can also work as a mycologist who is responsible for studying the behaviour of fungi and derive useful products from them. Another prospective role for them is that of a parasitologist, who is responsible for studying parasites. These are the job profiles amongst many other clinical and non-clinical opportunities that can be followed.
