Microbial Interactions & Microbial Ecology

Host-Pathogen Interaction along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic (diseases) and abiotic (salinity, drought, pollutions, etc.) stresses. The plant growth-promoting rhizobacteria (PGPR) and mycorrhizae, a key component of Host-Pathogen, could play vital roles in the maintenance of plant fitness and soil health under stressed environments,The host-pathogen interaction is defined as how microbes or viruses sustain themselves within host organisms on a molecular, cellular, organismal or population level. This term is most commonly used to refer to disease-causing microorganisms although they may not cause illness in all hosts. Because of this, the definition has been expanded to how known pathogens survive within their host, whether they cause disease or not. On the molecular and cellular level, microbes can infect the host and divide rapidly, causing disease by being there and causing a homeostatic imbalance in the body, or by secreting toxins which cause symptoms to appear. Viruses can also infect the host with virulent DNA, which can affect normal cell processes (transcription, translation, etc.), protein folding, or evading the immune response.

Soil-plant-microbe interactions along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic (diseases) and abiotic (salinity, drought, pollutions, etc.) stresses. The plant growth-promoting rhizobacteria (PGPR) and mycorrhizae, a key component of soil microbiota, could play vital roles in the maintenance of plant fitness and soil health under stressed environments, Plant-soil microbe interactions are critical to the health and productivity of ecosystems. These interactions involve a complex network of relationships where plants, soil, and microorganisms communicate and exchange nutrients. Plants exude a variety of organic compounds through their roots, which serve as food for soil microbes. In return, these microbes help plants by enhancing nutrient availability, decomposing organic matter, and protecting plants from pathogens. Mycorrhizal fungi, for instance, form symbiotic associations with plant roots, extending their reach and enhancing the uptake of water and essential nutrients like phosphorus.

Microbial ecology is the study of relationship between microbes and their surrounds, biased image of the role of microbes in nature obtained from laboratory studies of pure culture cultures  data leads to inappropriate conclusions about their relevance. Eg. E. coli grows in animals intestinal tracts but merely survive in aquatic environments , E. coli are transients and not residents of aquifers from which they can be isolated.Microbial ecology studies entail the use of conventional microbiological techniques (cultural / enumeration procedures, EM, radioactive tracer methods) and modern molecular techniques (gene analysis, nuclei acid probes, sequencing) .Ecology, Evolution and Biodiversity, formerly the Microbial Ecology and Evolution track encompasses many aspects of microbial and phage ecology and the roles of microbes in their natural environments. Our rapidly advancing knowledge of the complexity, immense diversity, and important roles of natural microbial communities will be highlighted in many of the exciting EEB sessions

The activities of complex communities of microbes affect biogeochemical transformations in natural, managed and engineered ecosystems. Meaningfully defining what constitutes a community of interacting microbial populations is not trivial, but is important for rigorous progress in the field. Important elements of research in microbial community ecology include the analysis of functional pathways for nutrient resource and energy flows, mechanistic understanding of interactions between microbial populations and their environment, and the emergent properties of the complex community.

A microorganism may be a microbe that has the potential to cause sickness. To cause an infection, microbes should enter our bodies. Microbes will enter the body through the four sites listed below: Respiratory tract (mouth and nose) e.g. respiratory  disease virus that causes the contagious disease.Gastrointestinal tract (mouth oral cavity) e.g. eubacteria epidemic cholera that causes cholera. Urogenital tract e.g. Escherichia  that causes    urinary tract infection. Breaks within the skin surface e.g. eubacteria tetani that causes tetanus, Microbial diseases are caused by microorganisms such as bacteria, viruses, fungi, and parasites. These diseases can range from mild infections, like the common cold, to severe illnesses, such as tuberculosis, HIV/AIDS, and malaria. Microorganisms can enter the body through various routes, including inhalation, ingestion, or direct contact with contaminated surfaces or bodily fluids. Once inside, they multiply and produce toxins or trigger immune responses that lead to symptoms of disease. The severity and spread of microbial diseases are influenced by factors such as the virulence of the microorganism, the host's immune system, and environmental conditions.

Microbiology & Infectious Diseases are affected by interaction between microorganisms in three ways. The indigenous flora (commensal microorganisms) of some mucous surfaces provide one of the main protective mechanisms against infection by pathogens (disease-producing microbes). The commensal populations interfere with the establishment of pathogens on mucous membranes by evoking anaerobic conditions, by competing for space and nutrients and by producing inhibitors. How, at the beginning of successful infection, pathogens in relatively small numbers overcome this protective activity of the commensal population is unknown, Microbiology is the branch of biology that focuses on the study of microorganisms, which include bacteria, viruses, fungi, and parasites. It delves into their structure, function, genetics, and ecological roles. Understanding microbiology is crucial in the context of infectious diseases, as many pathogens are microorganisms that can cause illness in humans, animals, and plants. Microbiologists investigate how these organisms spread, evolve, and interact with their hosts and environments. They play a vital role in developing treatments such as antibiotics and vaccines, as well as in designing strategies for disease prevention and control.
