  • This is an insider's account of 50 years of genetic studies of the soil-inhabiting microbes that produce most of the antibiotics used to treat infections, as well as anti-cancer, anti-parasitic and immunosuppressant drugs. The book begins by describing how these microbes - the actinomycetes - were discovered in the latter part of the nineteenth century, but remained a 'Cinderella' group until, in the 1940s, they shot to prominence with the discovery of streptomycin, the first effective treatment for tuberculosis and only the second antibiotic after penicillin to become a medical marvel.

  • This book is for anyone interested in the consequences of disturbance. What happens after the lava cools, or when the muddy floodwaters recede or an old road is abandoned? Primary succession is the process of ecosystem development on barren surfaces where severe disturbances have removed most vestiges of biological activity. It includes the development of complex systems from simple biotic and abiotic (non-biological) components. Primary succession starts when plants, animals and microbes colonize new surfaces. The process is influenced by local conditions, context and site history.

  • Microbes produce an extraordinary array of microbial defense systems. These include broad-spectrum classical antibiotics, metabolic byproducts, such as the lactic acids produced by lactobacilli, lytic agents such as lysozymes, numerous types of protein exotoxins, and bacteriocins, which are loosely defined as biologically active protein moieties with a bacteriocidal mode of action.

  • Though alternative methods of controlling insects, rodents, insect pests, pathogens, microbes and weeds have been developed, pesticides could not be replaced. The prosperous role of pesticides in the management of insect pests and diseases is indisputable. However, its nature of non selective toxicity towards other organisms and deposition in the environment warrants the legislation of usage. Pesticide use raises a number of environmental concerns.

  • The Twenty-First Century Physician: Expanding Frontiers The Era of Genomics In the spring of 2003, the complete sequencing of the human genome was announced, officially ushering in the genomic era. However, even before this landmark accomplishment, the practice of medicine had been evolving as a result of the insights gained from an understanding of the human genome as well as the genomes of a wide variety of microbes, whose genetic sequences were becoming widely available as a result of the breathtaking advances in sequencing techniques and informatics.

  • The human gastrointestinal tract microorganisms, termed the “microbiota,” have been investigated since the beginning of microbiological studies, when Antonie van Leeuwenhoek, the father of microbiology, investigated the microorganisms in his own stools. The human microbiota comprises trillions of microbes distributed in various niches throughout the intestinal tract and is one of the most complex microbial ecosystems on earth.

  • The structural carbohydrates that constitute plant fibre represent a major feed resource. Herbivorous animals, unable to produce fibre-degrading enzyme systems of their own, have evolved a range of strategies (Hume and Sakaguchi, 1991) to make use of a consortium of microbes, including bacteria, protozoa and anaerobic fungi, for this purpose...

  • Principles of Vaccine Use Route of Administration Microbes differ in their routes of infection, patterns of transmission, and predispositions for certain age groups. The route of vaccine administration (oral, intranasal, intradermal, transdermal, subcutaneous, or intramuscular) takes these factors into account in order to maximize protection and minimize adverse events. Vaccine development is more a pragmatic undertaking than an exact science, guided only in part by immunologic principles and shaped largely by the results of clinical trials.

  • Sorption is a process by which chemicals or organisms become attached to soils and/or the geologic rock material (aquifer solids) and removed from the water. Often the sorption process is reversible and solutes desorb and hence dissolved-solute plumes are retarded, rather than solutes being permanently retained by the solids. Cation exchange is the interchange between cations in solution and cations on the surfaces of clay particles or organic colloids. Filtration is a process that affects particulate contaminants (e.g.
