Indeed, microorganisms have an impact upon the earth's ecosystems that rivals that of the sun, the oceans, and the activities of humans and other living things. Microbiology is emerging as the key biological science. Microorganisms provide the models used in molecular biology for research. There is growing recognition of the potential of microorganisms in many applied areas. The ability of microorganisms to decompose materials, the potential of microorganisms as food supplements, the exploitation of microbial activity to produce energy such as methane gas, and the potential of new therapeutic substances produced by microorganisms – these and other uses are becoming increasingly attractive. Recombinant DNA technology makes it feasible to consider genetically manipulated microorganisms for commercial production of new andvaluable products for a variety of purposes (medicinal, fuel and food). ”We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm-a little universe, formed of a host of self-propagating organisms, inconceivably minute as the stars in heaven.” (Charles Darwin). Starting with this concept we became engaged in a race for leadership in science and technology. We are now experiencing a rapid shift of national and international priorities in research and development. In the field of science, and among the biological sciences, microbiology has gained a new stature. Microorganisms and their activities are increasingly central to many of the concerns of society, both nationally and internationally. ”The more formidable the contradiction between inexhaustible life-joy and inevitable fate, the greater the longing which reveals itself in the kingdom of poetry and in the self-created world of dreams hopes to banish the dark power of reality. The gods enjoy eternal youth and the search for the means of securing it was one of the occupations of the heroes of mythology and the sages, as it was of real adventurers in the middle ages and more recent times, but the fountain of youth has not been found, and cannot be found if it is sought in any particular spot on the earth. Yet it is no fable, no dream picture; it requires no adept to find it: it streams forth inexhaustible in all living nature.” (Ferdinand Cohn). In the light of this concept appears a unique perspective aiming to increase our awareness of microorganisms and their roles in illness, industry, and ecology, and that has the power to change people's lives. Although microbiology is primarily the study of microorganisms, it leads irrevocably to the study of animals, humans and their conditions. 4 GENERAL MICROBIOLOGY SIMONA -plasticine collection - IVANA Microbiology is rapidly becoming an important field of science, in which the geneticist, the cell physiologist, and the biochemist find, in the ground plowed by the pathologist, a fertile soil for new approaches to fundamental problems of the cell’s functioning and organization. Content When we first had the idea for this book we wanted to introduce microbiology in a way that left an exciting and indelible impression on young students and that made difficult concepts comprehensible. At the same time we aimed for a style and organization that produced a readable, current, accessible, and attractive book. Our primary emphasis is on a survey of general topics needed by students entering careers in allied health. My teaching of microbiology, and this book as a result of it, have been built around a central concept, that of the dual nature (”bad and good”) of microorganisms on the one hand, and of operating constituents of functional cells on the other hand. This manual attempts to be thorough without being exhaustive and sufficiently broad in scope to appeal to any interested student desiring a background on the topic. Organization Each course begins witha learning objective and key points, and a brief characterization of a microorganism to arouse curiosity in the field of Special Microbiology. This encourages students to develop an ever-expanding background of knowledge and improves their ability to understand increasingly sophisticated subjects. The text is organized into 15 courses grouped into informal units of information. The first group of courses is designed to develop the student's basic background and vocabulary. In Chapter 1 we explain the roles of microorganisms in ecosystem and biotechnology. Microbes serve many functions in almost any ecosystem on the earth. Some microbes (~10%) are pathogens. Chapter 2 contain the morphology of bacteria; shape of bacteria; bacterial classification and identification. It also surveys the basis morphological differences between bacteria; the forms of bacteria and their associations. Chapter 3 deals with bacterial cytology: the study of microscopic detail of bacteria; structures external to the cell wall; ultrastructure of a typical bacterial cell. Chapter 4 cover aspects of cell envelope structure and chemical composition; the three basic layers that can be identified in electron micrographs are the capsule, the cell wall and the cell membrane. Chapter 5 relies on the structure of cytoplasmic membrane and nuclear material; cytoplasmic inclusions, vacuoles, and nuclear material. Chapter 6 discusses about the certain species of bacteria that produce spores, either within the cell (endospores) or external to the cell (exospores); the spore is a metabolically dormant form which under appropriate conditions can undergo germination and outgrowth to form a vegetative cell. Chapter 7 discusses about reproduction and growth to bacteria, distinguish among the types of reproduction in prokaryotes, binary fission a type of reproduction in which the chromosome is replicated and resultant prokaryotic is an exact copy of the parental prokaryote, thus leaving no opportunity for genetic diversity. Chapter 8 is devoted to the essential nutrients: macronutrients and micronutrients; sources of essential nutrients; nutritional

Over the years, many studies have reported associations between the gut microflora under different pathological conditions. However, information about the role of gut metabolites and the mechanisms by which the gut microbiota affect health and disease does not provide enough evidence. Recent advances in next-generation sequencing and metabolomics coupled with large, randomized clinical trials are helping scientists to understand whether gut dysbiosis precedes pathology or gut dysbiosis is secondary to pathology. In this review, we discuss our current knowledge on the impact of gut bacteria, virome, and mycobiome interactions with the host and how they could be manipulated to promote health. Keywords: microbiome; biomarkers; personalized nutrition; microbes; metagenomics 1. Introduction The human body consists of mammalian cells and many microbial cells (bacteria, viruses, and fungi) which co-exist symbiotically.

Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants, and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 6,000 virus species have been described in detail, of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is forced to rapidly produce thousands of identical copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of: (i) the genetic material, i.e.

  • Lecture 7 Introduction to Viruses Introduction
    Lecture 7 Introduction to Viruses Introduction Virus, parasite with a noncellular structure composed mainly of nucleic acid within a protein coat. Most viruses are too small (100–2,000 Angstrom units) to be seen with the light microscope and thus must be studied by electron microscopes. In one stage of their life cycle, in which they are free and infectious, virus particles do not carry out the functions of living cells, such as respiration and growth; in the other stage, however, viruses enter living plant, animal, or bacterial cells and make use of the host cell's chemical energy and its protein- and nucleic acid–synthesizing ability to replicate themselves. Over 5,000 species of viruses have been discovered. Discovery of Viruses In 1884 the French microbiologist Charles Chamberland invented a filter, known today as the Chamberland filter or Chamberland–Pasteur filter that has pores smaller than bacteria. Thus he could pass a solution containing bacteria through the filter and completely remove them from the solution. In the early 1890s the Russian biologist Dmitri Ivanovsky used this filter to study what became known as the tobacco mosaic virus. His experiments showed that extracts from the crushed leaves of infected tobacco plants remain infectious after filtration. At the same time several other scientists proved that, although these agents (later called viruses) were different from bacteria, they could still cause disease, and they were about one hundredth the size of bacteria. In 1899 the Dutch microbiologist Martinus Beijerinck observed that the agent multiplied only in dividing cells. Having failed to demonstrate its particulate nature he called it a "contagium vivum fluidum", a "soluble living germ".

In healthy individuals, this complex ecosystem remains stable and resilient to stressors. There is significant attention on the understanding of the composition and function of this intestinal microbiota in health and disease. Current developments in metaomics and systems biology approaches allow to probe the functional potential and activity of the intestinal microbiota. However, all these approaches inherently suffer from the fact that the information on macromolecules (DNA, RNA and protein) is collected at the ecosystem level. Similarly, all physiological and other information collected from isolated strains relates to pure cultures grown in vitro or in gnotobiotic systems. It is essential to integrate these two worlds of predominantly chemistry and biology by linking the molecules to the cells. Here, we will address the integration of omics- and culture-based approaches with the complexity of the human intestinal
