The theme “To explore the microbial world and it’s applications for the benefit of mankind’’ that focuses on detailed study of structure, life and mechanism of action of microbes to deal with infectious diseases and utilize it for the health of future generation. Microbiology is a vast field of study of microorganisms covering wide range of studies that are affecting human beings and animals in both positive and negative ways. With the advent of newly evolved strains of bacteria, viruses and other microorganisms, mortality rates have been affected in a very drastic manner. Pharmaceutical companies are under pressure to design new drugs as people are developing drug-resistant infections. Other than the disadvantages of the growth of microorganisms, there are many advantages we get from their growth like in food industries, gut microbiota, etc. Food industries utilize yeast for manufacturing of bread and use microorganisms for fermentation, production of alcohol and beer. Gut microbiology is itself an expanded field of research that involves study of microorganisms hosting inside our body and surviving symbiotically. Microorganisms residing in other body parts like vaginal canal, etc., protect our body from serious infections by fighting against the growth of microorganisms from outside environment. There are still many aspects of microbiology that are required to be mentioned as the miniature world of microbes is too huge to be explored.
