The study of microscopic organisms is called microbiology. Micro-organisms are very small organisms which are not visible through naked eye. These organisms include algae, bacteria, moulds, protozoa, yeasts and viruses. Sometimes they are even referred to as microbes and are studied under microscope, being very small in appearance
Microbiologists study and investigate micro-organisms and their relationships with man, animals and plants
Some of the sub-categories of microbiologists are as follows.
MEDICAL MICROBIOLOGISTS: Medical microbiologists study the role played by micro-organisms in inflicting diseases in humans and animals. They research and investigate these organisms to find ways to cure and prevent, occurrence of these diseases. Major breakthroughs have been made in this field and efforts are on all over the world to find solutions to many more dreadful diseases especially AIDS.
AGRICULTURAL MICROBIOLOGISTS: India is still an agricultural economy and microbiologists play an important role in improving its size and shape i.e. the output and quality. Agricultural microbiologists study plant diseases, the role of micro-organisms in soil fertility and spoilage of farm products. Advances and inventions made in agricultural microbiology over the years has contributed in increasing agricultural output.
INDUSTRIAL MICROBIOLOGISTS: Industrial microbiologists work with industries producing products such as alcoholic beverages, amino acids, citric acids, Vitamin C and antibiotics etc. with the help of micro-organisms.
MARINE MICROBIOLOGISTS: Marine microbiology deals with the micro-organisms present in the ocean. It is a relatively new division of microbiology and promises to be an exciting one.
GENERAL MICROBIOLOGISTS: General microbiology focuses on the fundamentals and basic features of micro-organisms including ecology, metabolism, genetics, physiology and structure
Microbiologists can further specialize in the study of micro-organisms in the fields of their interest such as bacteriology; study of bacteria, mycology; study of fungi and virology; study of viruses.
Microbiologists find jobs in many places like research and development laboratories of government and private hospitals, research organizations, pharmaceutical, food, beverage and chemical industries. Being closely related to biotechnology, there are many similarities between them, making microbiology also a very promising career option.
