Book Description
This book describes biofilms in the context of hygiene in food safety and hospital facilities, starting with bacterial adhesion as an initial step of cell colonization, followed by the growth and maturation of biofilms. The main focus of this book is on biofilm prevention and control. The resistance of bacteria to several antibiotics is a global public health problem, not limited to hospital facilities, but also to other sectors, including the food industry. This raises questions about whether effective cleaning and disinfection reduce the risk of food-borne and hospital-acquired illness. Can the surface characteristics be treated to prevent bacterial adhesion and, consequently, the formation of biofilms? Biofilms are complex communities of bacteria attached the surfaces, with fully developed architecture and highly organized interactions. A better understanding of the biofilm lifecycle, with advanced strategies of physical, chemical and biological actions, would reduce the risk of infection. The question is not whether the preventive and control measures will play a significant role in public health, but rather what the implications of their use will be for hygiene in the food industry and hospital facilities.

Book Description
Approximately 60% of all hospital-associated infections, over one million cases per year, are due to biofilms that have formed on indwelling medical devices. Device-related biofilm infections increase hospital stays and add over one billion dollars/year to U.S. hospitalization costs. Since the use and the types of indwelling medical devices commonly used in modern healthcare are continuously expanding, especially with an aging population, the incidence of biofilm infections will also continue to rise. The central problem with microbial biofilm infections of foreign bodies is their propensity to resist clearance by the host immune system and all antimicrobial agents tested to date. In fact, compared to their free floating, planktonic counterparts, microbes within a biofilm are 50 – 500 times more resistant to antimicrobial agents. Therefore, achieving therapeutic and non-lethal dosing regimens within the human host is impossible. The end result is a conversion from an acute infection to one that is persistent, chronic, and recurrent, most often requiring device removal in order to eliminate the infection. This text will describe the major types of device-related infections, and will explain the host, pathogen, and the unique properties of their interactions in order to gain a better understanding of these recalcitrant infections.

Book Description
Biofilms are highly organized polymicrobial communities that are embedded in an extracellular matrix and formed on natural and artificial surfaces. In the oral cavity, biofilms are formed not only on natural teeth, but also on restorative materials, prosthetic constructions, and dental implants. Oral diseases like caries, gingivitis, periodontitis, and also pulp inflammation are associated with biofilms. This publication is an up-to-date overview on oral biofilms from different clinically relevant perspectives. Experts comprising basic researchers and clinicians report on recent research relating to biofilms - from general summaries to recommendations for daily clinical work. This book covers all aspects of oral biofilms, including models used in the laboratory, biofilms in dental water unit lines, periodontal and peri-implant biofilms, caries-related biofilms, halitosis, endodontic biofilms, and Candida infections, as well as biofilms on dental materials and on orthodontic appliances. Several chapters deal with anti-biofilm therapy, from the efficacy of mechanical methods and the use of antimicrobials, to alternative concepts. This publication is particularly recommended to dental medicine students, practitioners, other oral healthcare professionals, and scientists with an interest in translational research on biofilms.

Book Description
This book will cover both the evidence for biofilms in many chronic bacterial infections as well as the problems facing these infections such as diagnostics and treatment regimes. A still increasing interest and emphasis on the sessile bacterial lifestyle biofilms has been seen since it was realized that that less than 0.1% of the total microbial biomass lives in the planktonic mode of growth. The term was coined in 1978 by Costerton et al. who defined the term biofilm for the first time.In 1993 the American Society for Microbiology (ASM) recognised that the biofilmmode of growth was relevant to microbiology. Lately many articles have been published on the clinical implications of bacterial biofilms. Both original articles and reviews concerning the biofilm problem are available.

Book Description
Living in biofilms is the common way of life of microorganisms, transiently immobilized in their matrix of extracellular polymeric substances (EPS), interacting in many ways and using the matrix as an external digestion and protection system. This is how they have organized their life in the environment, in the medical context and in technical systems – and has helped make them the oldest, most successful and ubiquitous form of life. In this book, hot spots in current biofilm research are presented in critical and sometimes provocative chapters. This serves a twofold purpose: to provide an overview and to inspire further discussions. Above all, the book seeks to stimulate lateral thinking.

Book Description
Until now, techniques for studying biofilms- the cellular colonies that live in drinking water systems, wastewater operations, even ground and surface water- have been limited. Yet during the last decade, biofilms have become a critical element in water quality preservation systems, a key component of wastewater treatment biological reactions and the subject of extensive microbiological inquiry. An understanding of biofilm development, structure and dynamics is one condition for improving water supplies and for addressing technical problems such as biofouling, corrosion and bioweathering. Biofilms: Investigative Methods and Applications provides the first in-depth assessment of current and experimental ways to study biofilms, both in sample form and in situ. It shows how sensors, microscopy, lasers, and calorimetry, among other tools, can be used to obtain data on the morphology and metabolism of biofilms. This text is the first to organize and examine the best methods for investigating biofilms. It covers culture-based methods and emerging nondestructive techniques. It also shows how they can be used to characterize biofilms in a variety of manmade settings, such as sewers, wastewater plants, and drinking water distribution systems, as well as in karsts and groundwater sources. In clarifying the way biofilms are studied, the book offers new insights into these living films. It also applies inquiry techniques to the many problems confronting the environmental specialist-corrosion control, biofouling, and the improvement of fixed reactors in wastewater treatment. At the same time it explains technologies for the controlled growth of biofilms and shows how biofilms can be effectively monitored and subjected to quantitative analysis. The technical information in Biofilms: Investigative Methods and Applications is designed to be of use to engineers and researchers and to be helpful in the generation of electronic data.

Book Description
The Perfect Slime presents the latest state of knowledge and all aspects of the Extracellular Polymeric Substances, (EPS) matrix – from the ecological and health to the antifouling perspectives. The book brings together all the current material in order to expand our understanding of the functions, properties and characteristics of the matrix as well as the possibilities to strengthen or weaken it. The EPS matrix represents the immediate environment in which biofilm organisms live. From their point of view, this matrix has paramount advantages. It allows them to stay together for extended periods and form synergistic microconsortia, it retains extracellular enzymes and turns the matrix into an external digestion system and it is a universal recycling yard, it protects them against desiccation, it allows for intense communication and represents a huge genetic archive. They can remodel their matrix, break free and eventually, they can use it as a nutrient source. The EPS matrix can be considered as one of the emergent properties of biofilms and are a major reason for the success of this form of life. Nevertheless, they have been termed the “black matter of biofilms” for good reasons. First of all: the isolation methods define the results. In most cases, only water soluble EPS components are investigated; insoluble ones such as cellulose or amyloids are much less included. In particular in environmental biofilms with many species, it is difficult to impossible isolate, separate the various EPS molecules they are encased in and to define which species produced which EPS. The regulation and the factors which trigger or inhibit EPS production are still very poorly understood. Furthermore: bacteria are not the only microorganisms to produce EPS. Archaea, Fungi and algae can also form EPS. This book investigates the questions, What is their composition, function, dynamics and regulation? What do they all have in common?
