The Aerobiological Pathway Of Microogranisms

Provides a background and explanation of the aerobiological pathway and of microbial survival and infectivity. Presents, clearly and simply, the most current information available, giving a clear picture of the aerobiological behavior of micro-organisms. Covers the physical and the biological aspects of aerosol behavior. Explains why microbial aerosols behave as they do rather than just stating the outcome of a situation. Covers viability and infectivity of micro-organisms, and provides a discussion of the role of temperature for aerosol survival and disease transmission by aerosols. Relates these to the biohazards to be found in public health, laboratories, agriculture, microbiology, genetic engineering, industry, environmental studies, and space exploration.

A new textbook which aims to provide a detailed theoretical background to the aerobiological pathway of micro-organisms. A special feature is the previously unpublished application of catastrophe to the role of relative humidity and temperature in aerosol survival.

Aerobiology is the science that studies the biological component of the atmosphere and its effects on living systems and on the environment. This term was used for the first time in 1935, but the attention of scientists to the biological component of the atmosphere goes back to 1769, when the Italian biologist Spallanzani carried out a series of experiments that disproved the concept of spontaneous generation of life and proved the presence of viable microorganisms in the air. Aerobiology has marked characteristics of interdisciplinarity: its application fields range from respiratory diseases to the airborne outbreak of animal and vegetal diseases and to the biodegradation of substances and materials. The latter is the subject of this book. The purpose of aerobiological research applied to the conservation of cultural heritage is to evaluate the risk of alteration by airborne microorganisms of materials forming artefacts of historical, artistic and archaeological interest. Airborne spores and vegetative structures may develop on different substrates and may be a cause of degradation, in relation to the types of materials, the microclimatic situation and the pollution of the conservation environments. The qualitative and quantitative evaluation of the biological component of air, performed by means of targeted analysis campaigns, and of the characteristics of materials and environments, supplies indispensable information for the evaluation of the actual risk and the planning of interventions. This book is divided into four main parts.

This volume presents detection and identification methods for bacteria and yeast. Chapters are written by expert laboratory practitioners and instrument makers and focuses on those methods that show widespread practical application, such as ATP luminescence. Food applications include rapid detection and quantitation of bacteria in raw milk, pasteurized milk, other dairy products, and raw meat. Other topics include brewing applications for beverages, starter culture monitoring, clinical analyses, blood and urine analysis procedures, analysis of aerosols, bioprocess safety, and biodeterioration. This book is a must for microbiologists in food quality labs and clinical labs.

A bioaerosol is a colloidal suspension of liquid droplets or solid particles in air whose components contain or have attached to them one or more microorganisms. Bioaerosols are an exciting and vital object of study because the attached microbes play a critical role in human, animal and environmental health. In an era of genetically engineered microorganisms and the application of biopesticides, bioaerosols are increasingly an environmental problem, both indoors and outdoors, and can affect entire ecosystems. Atmospheric Microbial Aerosols examines naturally occuring bioaerosols, as well as bioaerosols generated by human activity. Included in this volume is a complete array of topics concerned with outdoor microbial bioaerosols ranging from the physical and chemical to the meteorological and microbial. It will be of great interest as a starting point for researchers interested in outdoor microbial bioaerosols as well as for those interested in atmospheric dispersion models, new equipment, and government regulations.

The single most comprehensive resource for environmental microbiology Environmental microbiology, the study of the roles that microbes play in all planetary environments, is one of the most important areas of scientific research. The Manual of Environmental Microbiology, Fourth Edition, provides comprehensive coverage of this critical and growing field. Thoroughly updated and revised, the Manual is the definitive reference for information on microbes in air, water, and soil and their impact on human health and welfare. Written in accessible, clear prose, the manual covers four broad areas: general methodologies, environmental public health microbiology, microbial ecology, and biodegradation and biotransformation. This wealth of information is divided into 18 sections each containing chapters written by acknowledged topical experts from the international community. Specifically, this new edition of the Manual Contains completely new sections covering microbial risk assessment, quality control, and microbial source tracking Incorporates a summary of the latest methodologies used to study microorganisms in various environments Synthesizes the latest information on the assessment of microbial presence and microbial activity in natural and artificial environments The Manual of Environmental Microbiology is an essential reference for environmental microbiologists, microbial ecologists, and environmental engineers, as well as those interested in human diseases, water and wastewater treatment, and biotechnology.
