Microbiology is concerned with the structure, function, and categorization of these organisms as well as how to use and control their behaviours. A diverse range of fundamental living forms, including as bacteria, viruses, moulds, algae, and protozoans, make up this group. In science, microorganisms are investigated. In the latter part of the 19th century, Robert Koch and Louis Pasteur laid the foundation for it. Since then, several microorganisms that cause pathogens have been identified, and preventative measures have been developed. Moreover, methods for controlling the behaviour of diverse bacteria have been discovered to benefit industry, medicine, and agriculture. For instance, penicillin and other medicines are produced by moulds.

Using enzymes and numerous laboratory procedures, recombinant DNA technology allows for the manipulation and isolation of desired DNA segments. DNA from other species can be combined (or spliced) with this technique, or new genes with distinct functions can be made. Recombinant DNA is the term used to describe the resultant copies.

In biology, recombinant DNA technology is a crucial research tool. It enables the manipulation of DNA fragments for laboratory research. A fragment of DNA is inserted into a bacterial or yeast cell using a number of scientific techniques. Once inside, the bacteria or yeast will duplicate both the DNA and their own. Important proteins like insulin and growth hormone that are utilised in the treatment of human ailments have been produced with success using recombinant DNA technology.

Pathogenicity is specifically the characteristic or state of having the capacity to cause illness, whereas virulence is the ability of an organism to cause disease, or the level of pathogenicity within a group or species.Virulence factors are substances generated by microorganisms that cause illness. Toxins, surface coatings that prevent phagocytosis, and surface receptors that bind to host cells are a few examples.

In addition, Salmonella protein SopE, which functions as a GEF and activates the GTPase to produce additional GTP, is one example of a bacterial virulence factor that behaves like a eukaryotic protein. Nothing is changed, but the usual cellular internalisation process is overdriven, which makes it simpler for the bacteria to infiltrate a host cell.

Although it is only believed that the name "biotechnology" has been in use for a century or so, people have been using various sorts of biotechnology for thousands of years. A collection of ideas, methods, and equipment used in biotechnology to create or alter living things is referred to as synthetic biology.

From the viewpoint of the biotechnology sector, synthetic biology has already been used to design the effective synthesis of tiny organic compounds for the chemical sector and is significantly advancing the engineering of mammalian cells for medical treatment.

All of the microorganisms that naturally inhabit our bodies and inside of us, including bacteria, fungus, and viruses, are collectively referred to as the microbiome. Despite their small size, which makes them invisible without a microscope, microorganisms have a significant impact on human health and wellbeing.

All of a microbiota's genetic material is contained in the microbiome (the entire collection of microorganisms in a specific niche, such as the human gut). The metagenome of the microbiota is another name for this.The microbiome, made up of prokaryotic and eukaryotic microbial communities, and humans are supra-organisms that co-evolved. These microbiomes provide crucial ecological services that are crucial for maintaining human health.

Aquatic microbiology focuses on the study of bacteria in freshwater or saltwater aquatic settings. It covers the behaviour and interactions of tiny plants, animals, bacteria, viruses, and fungus in an aqueous environment. Plankton, nekton, and benthos are the three main categories of aquatic creatures. They dwell in various places and move in different ways. Plankton are microscopic aquatic creatures that are unable to move independently.

Due to their functions in the creation and breakdown of organic matter, nutrient intake and regeneration, foodweb exchanges, and biogeochemical transformations, microorganisms play a crucial role in the structure of aquatic ecosystems.

Viruses, bacteria, fungus, protozoa, and helminths are the five main categories of disease-causing agents (worms). Microbiology studies viruses, bacteria, and fungus, whereas parasitology studies protozoa and worms, which are typically classed together as parasites. Many physiological compartments, including intracellular and extracellular, can support the growth of infectious pathogens.

Infectious agents may be Bloodborne Pathogens (BBP):

Hepatitis B, Hepatitis C
Influenza (FLU) Avian. Swine
Methicillin-resistant A streptococcal infection (MRSA)
Tuberculosis (TB)
Significant Acute Respiratory Syndrome (SARS)
Middle East Respiratory Syndrome (MERS) or Arabian Gulf Respiratory Syndrome 

The study of cell structure and function is known as cell biology, and it is based on the idea that a cell is the basic building block of all life. A thorough grasp of the tissues and organisms that cells make up is made possible by concentrating on the cell.

Cell biology aims to comprehend the make-up and physiological operation of individual cells, as well as how they interact with their surroundings and cooperate in huge numbers to produce tissues and organisms.It is is an essential component in the quest for the best treatments and a thorough understanding of diverse illnesses. Almost all diseases, including cystic fibrosis, diabetes, malaria, and different forms of cancer, are brought on by problems at the cell or molecular level.

A crucial area of the medical and biological sciences, immunology is the study of the immune system. Our immune system defends us against infection via a number of different mechanisms. Diseases including cancer, allergies, and autoimmunity can develop if the immune system is not working properly.

The immune system is a group of cells and proteins that work to defend the skin, nasal passages, digestive tract, and other organs from external antigens including viruses, cancerous cells, poisons, and microbes (organisms like bacteria, fungus, and parasites). Innate immunity and adaptive immunity can be conceptualised as its two "lines of defence" in a simplified manner.

The future of microbiology is promising. New opportunities have emerged as a result of social and scientific shifts in the study of infectious illness, microbial ecology, plant and animal pathology, and biotechnology. These developments promise to enhance human life and the health of the environment.

Researchers develop novel applications in cutting-edge research to comprehend the intricacy of host microbial interactions and recognise illnesses.

This field encompasses basic studies on the biochemistry, physiology, cell biology, ecology, evolution, and clinical aspects of microbes, including the host's reaction to these invaders.

Any substance that eliminates bacteria or inhibits their development or multiplication is considered an antibiotic.An antibiotic is a chemical compound made by microorganisms that has the power to stop or kill bacteria and other microorganisms at low quantities. 

Antibiotics, antivirals, antifungals, and antiparasitics are examples of antimicrobials, which are drugs used to prevent and cure infections in people, animals, and plants.
As gram-positive bacteria have primarily peptidoglycan cell walls as opposed to gram-negative bacteria, which also have a lipopolysaccharide and protein layer, penicillin is more efficient against gram-positive bacteria.

Antimicrobial resistance happens when bacteria, viruses, fungi, and parasites transform in a way that makes the drugs used to treat the diseases they cause ineffective. The term "superbugs" is frequently used to describe germs that have developed resistance to most antimicrobials.


The study of viruses and virus-like organisms is known as virology, and it includes research on their taxonomy, ability to spread illness, culture methods, and genetic makeup. In microbiology or pathology, virology is frequently regarded as a subfield.
Early discoveries in the chemical and physical sciences were a necessity for the field of virology, but soon viruses were used as instruments to investigate fundamental biochemical functions in living things.
Host cells can engage antiviral signalling in response to viral infection to stop viral replication and inform nearby cells of viral infection. Antiviral response activation is extremely variable, both in terms of quantity (degree of pathway activation) and quality, in infected cells for unknown reasons.

Agricultural microbiology is a subfield of microbiology that studies illnesses of plants and animals as well as bacteria that are connected with plants. It also covers the microbiology of soil fertility, including the microbial breakdown of organic materials and the alteration of soil nutrients. The fertility of the soil is increased by microbes. Certain microbes, like bacteria, are excellent decomposers. They break down decaying organic materials. The land will become fruitful when this stuff is added to it.


Mycology is the study of fungi, which also includes yeasts and mushrooms. Many fungi are helpful in both medical and business. Penicillin, streptomycin, and tetracycline, as well as other medicines like statins, were developed as a result of mycological research (cholesterol-lowering drugs).  In addition, mycology plays a significant role in the manufacturing of colours and inks, as well as in the dairy, wine, and baking sectors. 

Mycology is required to identify good and toxic fungus, treat crops, and stop further infections. The commercial value of several secondary metabolites produced by fungus is enormous. In order to reduce competition in the natural environment, fungi naturally create antibiotics that can either kill or stop the growth of bacteria. Fungi may be used to isolate important medicines like penicillin and cephalosporins.


In the field of study known as biomaterials, researchers create materials that may be used to control a therapeutic or diagnostic operation using live organisms. Professors in BE are working on biomaterials that can be used to control immune cells, develop new medication delivery systems, and build intricate tissue microstructures. Antimicobial biomaterials often have antifouling coatings that have limited adherence to microorganisms or even repelling qualities, or antimicrobial coatings that have the ability to kill germs that are near the surface.

Novel carbon-based nanomaterials including graphene-based nanostructures, carbon nanotubes, nanodiamonds, and fullerenes are valuable for biomaterial applications because of their antibacterial properties, enhanced solubility, biocompatibility, and cellular responsiveness.

Immunization is an unquestionable human right and an essential part of primary healthcare. It's also among the finest investments in health that money can buy. Infectious illness outbreaks can be prevented and controlled with the use of vaccines. They support the security of the world's health and will be a crucial weapon in the fight against antibiotic resistance.

Every year, vaccinations save millions of lives and contribute to global health and development. By bolstering your body's natural defences, vaccines lower your chance of contracting a disease. Your immune system reacts to vaccinations.

A vaccination stimulates the immune system, and many vaccines introduce weak or inactive germs into our bodies. mRNA vaccines not so. Instead, mRNA vaccines instruct our cells to manufacture a protein—or even just a portion of a protein—that prompts an immune response in our bodies using mRNA that was synthesised in a lab.

Infections and sickness can be avoided by maintaining a healthy microbiome. People and animals may be at risk for illness due to an imbalanced microbiome. Unbalanced microbiomes can get overrun and overgrow by diseases, particularly resistant infections and C. difficile. Less defence against infection can be provided by the body. It might be difficult or even impossible to cure infections brought on by resistant microbes.

Microbiology and genetic engineering both include the field of microbial genetics. Microorganisms are studied in microbial genetics for a variety of reasons. Bacteria and archaea are the microbes that are seen. Moreover, several protozoa and fungi are utilised as research subjects in this area. Studies of genotype and expression system are part of the study of microorganisms. Genotypes are an organism's hereditary makeups. Microbial genetics includes the area of labour and research known as genetic engineering.

Toxic compounds need to have a fast rate of biodegradation in order to diminish their concentration and, consequently, their poisonous impact quickly. In contrast, chemicals that are extremely persistent will continue to be hazardous for a very long period. Municipal solid trash frequently include biodegradable waste, such as green waste, food waste, paper waste, and biodegradable plastics.

Other biodegradable wastes include manure, sewage, slaughterhouse waste, and human faeces.Biodegradation is the process in which organic substances in the environment are naturally broken down into simpler compounds, mineralized, and redistributed through elemental cycles like the carbon, nitrogen, and sulphur cycles.

Bioremediation is the biological detoxification or degradation of pollutants found in soil, wastewater, or industrial sludge. Although this process can involve microorganisms (bacteria, fungus, etc.), plant-assisted bioremediation is more commonly known as phytoremediation.

Across the world, bioremediation helps purify water supplies, cultivate better soil, and enhance air quality. Yet, bioremediation is less invasive and can help with environmental impact repair without harming sensitive ecosystems, in contrast to excavation-based remediation techniques, which can be disruptive.

Using bioremediation techniques has a number of benefits over other remediation methods, including the following: A hazardous waste site can be treated using bioremediation technologies for a lot less money than it would cost to treat it using conventional treatment methods because: (1) biologically-based remediation detoxifies hazardous substances rather than merely transferring contaminants from one environmental medium to another; (2) bioremediation generally causes less environmental disruption than excavation-based processes; and (3) it is generally less disruptive to the environment than excavation-based processes.

Clinical microbiology is concerned with isolating and characterising infectious organisms in order to control and treat them in patients. Bacteria, fungi, viruses, and parasites can all cause infections. To help with illness diagnosis, clinical microbiologists carry out a wide variety of clinical laboratory tests on samples obtained from people, animals, and plants. Medical scientists may include clinical and medical microbiologists whose work directly pertains to studying human health.

To help with illness diagnosis, clinical microbiologists carry out a wide variety of clinical laboratory tests on samples obtained from people, animals, and plants. Medical scientists may include clinical and medical microbiologists whose work directly pertains to studying human health. The invasion and growth of microorganisms that are not ordinarily present in the body, such as bacteria, viruses, and parasites. An infection may be subclinical and exhibit no symptoms, or it may be clinically evident and exhibit symptoms.A pathogen must effectively complete all four of the pathogenesis processes or stages in order to produce disease: exposure (contact), adhesion (colonisation), invasion, and infection.

With an emphasis on human health and illness, public health microbiology is a specialty that includes the domains of human, animal, food, water, and environmental microbiology. In order to provide fast and accurate information on pathogen identification and characterisation required for efficient infectious disease prevention and management, particularly in response to epidemic risks, public health microbiology laboratory systems must be well-capable.
Zoonoses, pathogens spread in healthcare facilities, tropical illnesses, food safety, vaccine trials, and social and public health elements of infectious disease are all included in the vast field addressed.

The study of microorganisms that live in both natural and man-made settings is known as environmental microbiology. The findings of Antony van Leewenhoeck, which were published in 1677, serve as the foundation for scientific study in this area. Air, soil, and water microbiology are all included in this field of study. The four parts of the environment are the hydrosphere, lithosphere, biosphere, and atmosphere. The study of microorganisms in the soil, water, and air, as well as their use in bioremediation to lessen environmental pollution through the biological breakdown of pollutants into non-toxic or less hazardous chemicals, are the focus of environmental microbiology.

The creation of oxygen, symbiotic interactions, evolution, and decomposition are just a few of the crucial functions that microorganisms play in ecosystems. Dead animal or plant materials is broken down into simpler molecules during decomposition. Only the microbes that make their way into the dead stuff can explain why this process takes place.

The field of molecular biology studies the compositions, relationships, structures, and biological roles of many biomolecules, such as amino acids, nucleic acids (DNA and RNA), proteins, carbohydrates, and lipids.Applications for molecular biology techniques include the prevention and treatment of disease, the creation of novel protein products, and the modification of plants and animals to produce desired phenotypic features.

Modern molecular medicine includes the use of several molecular biology approaches to the study of illness, disease genes, and disease gene activity. The invention of recombinant DNA and cloning techniques has made it feasible to examine illness genes and their function in an unaffected person.

Nucleic acids, such as DNA and RNA, as well as protein production in cells, are significant subjects studied in this course. A subfield of biology called molecular biology is closely connected to the fields of biochemistry, cell biology, genetics, and genomics.
