Clinical Microbiology deals with study of the interrelation of macro- and microorganisms under normal and pathological conditions. It provides inclusive information on the identification of different microorganisms and features of newly recognized and re-emerging infectious diseases, antimicrobial agents and their applications, and diagnostic laboratory technologies. Microbial profiling helps in the relegation of microbes predicated on experiments, resulting prompt identification of their taxonomy. It also helps to identify the good and bad microbes that have high impact in our day-to-day life.

A virus is a tiny infectious agent/ organism that causes an infection in the body and contaminate plants, animals, insects and even microscopic organisms. Viruses can be transmitted in numerous ways, such as through contact with an infected person, swallowing, inhalation, or unsafe sex. Viruses are reliant on host cell machinery for their replication and both bacterial and animal viruses are responsible for taking a recombinant DNA revolution. Viruses show solid immunological reactions with both cell and humoral immunity. Many antivirals were created to treat viral diseases by targeting viral replication stages.

Sexually transmitted disease or infection can affect both men and women through sexual contact. Antibiotics can make a treatment for STDs caused by bacteria, yeast, or parasites, STDs caused by a virus has no cure. The human immunodeficiency virus is a lentivirus which attacks the immune system, which is our body’s natural defence against illness, causes HIV infection and AIDS. HIV diagnosis is done by testing your blood or saliva for antibodies of the virus. Clinical trials are the main way to determine if new medical approaches to HIV/AIDS are safe and effective in people. Proper hygienic living and habit will be a major step to fight against the diseases cause by the STD or STI.

Vaccines which are biological preparation containing an infectious agent- probably weakened or a killed form of the actual infectious agent, viz., bacteria or virus or the toxin therefor, along with other substances. Vaccines confer for the protection against various infections- bacterial and viral. They are divided into Antibiotics (against bacterial infections), Antivirals (against viral infections), Antifungals (against fungal infections), Antiprotozoal (against protozoal infections), anti-helminths and nematicides (against nematodes and helminths) etc. Traditional viral vaccines, such as that of influenza, for polio and hepatitis B, elicit neutralizing antibodies that play a vital role to protect immunity. Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen.

Microbes have been proved as beneficial for the survival of mankind. Microbes have a significant role to play in the discovery of antibiotics, microbial vaccines, anti-microbial coatings, immune system modulating agents, disinfectants, manufacturing of biofuels and bioplastics, using biotransformation for the production of chemicals and other therapeutic agents. Microbes are superlatively appropriate for the studies of biochemical and genetic, and showed to be successful in providing information on genetic codes and gene regulations. Conjugation, transformation, and transduction are the important methods for mapping the genes on bacterial chromosomes. Recombinant DNA technology, selection, mutation, reproductive cloning, and use of plasmids form a part of genetic engineering tools.

Human Virology accomplishes infections which attack human. Hepatitis is the inflammatory condition of the liver causes by the viral infection. Hepatitis viruses are mainly spread by contaminated food or water, sexually transmitted, from mother to baby during pregnancy or childbirth, infected blood transfusion or sharing of needles. Hepatitis A, B, and D are preventable with immunization. Herpes simplex is a viral disease caused by the herpes simplex virus which causes primarily face, mouth, throat, eye, and central nervous system infections. Research leads into vaccines for both prevention and treatment of herpes infections.

Mycology comprises the study of biochemical and genetic properties and taxonomy of fungi and their use to humans as a source for tinder, food, medicine, and entheogens, as well as their dangers, such as toxicity or infection. Medical Mycology is gaining more importance in the study of disease causing and as well as other medically important fungi with their interactions with the host-cells. Algae study is called as Phycology. These are the primary producers in the aquatic ecosystem, are extremely essential in the growth of microorganisms in the water eco-systems. It is found to be pseudo-plants, hence given a separate classification. In most cases, algae are single-celled and only few species are multicellular. Phytoplankton and microalgae are a type of algae, with some species of algae being large, capable of growing into seaweeds.

Veterinary Microbiology is concerned with microbial diseases of domesticated animals that provide food and other useful products. Veterinary Microbiology which is an important platform, gives veterinarians and microbiologists an inter-disciplinary forum, so that they can study various aspects of the infections which is caused by the pathogenic microorganisms. The emerging virus leads to the health issue for the animals that may cause death and misery to the animals. Various viral or bacterial diseases/infections are also naturally transmissible from vertebrate animals to humans.

Bacteria play an essential role in the biosphere and certain key processes, such as, the production and oxidation of methane, soil formation, conversion of rock to soil etc. Traditional methods of bacterial identification depend on phenotypic identification of the causative organism using gram staining, culture and biochemical methods. Microbes have been around for more than 3.5 billion years. Humans depends microbes to stay healthy, and many microbes need the environments provided by the human body to survive. Major researches in bacteriology over the past years resulted in the development of many useful vaccines.
