Bacterial Fish Pathogens


Book Description

This book puts emphasis on the isolation, taxonomy, diagnosis (phenotypic, serology and molecular biology), epizootiology, pathogenicity mechanisms, and methods of disease control (by vaccination, immunostimulation, probiotics, prebiotics, plant products, and antimicrobial compounds. Co-infections, which are attributed to more than one microbial species have been discussed. Shortcomings in knowledge have been highlighted. This sixth edition is the successor to the original version, first published in 1987, and which fills the need for an up-to-date comprehensive text on the biological aspects of the bacterial taxa which cause disease in finfish. The book is primarily targeted at researcher workers, including postgraduate students, and diagnosticians. It is anticipated that the readership will include veterinary microbiologists, public health scientists and microbial ecologists.




Fish Viruses and Bacteria


Book Description

Taking a disease-based approach, Fish Viruses and Bacteria: Pathobiology and Protection focuses on the pathobiology of and protective strategies against the most common, major microbial pathogens of economically important marine and freshwater fish. The book covers well-studied, notifiable piscine viruses and bacteria, including new and emerging diseases which can become huge threats to local fish populations in new geographical regions if transported there via infected fish or eggs. An invaluable bench book for fish health consultants, veterinarians and all those wanting instant access to information, this book is also a useful textbook for students specializing in fish health and research scientists initiating fish disease research programmes.




Bacteria and Fungi from Fish and other Aquatic Animals, 2nd Edition


Book Description

This practical book provides an updated resource for the identification of bacteria found in animals inhabiting the aquatic environment, illustrated with colour photos. It contains expanded biochemical identification tables to include newly identified pathogenic and saprophytic bacteria, molecular identification tests now available for a greater number of aquatic bacterial pathogens, more information on the pathogenesis and virulence of each organism and new coverage of traditional and molecular identification of fungal pathogens and quality assurance standards for laboratories.




Aquaculture Nutrition


Book Description

Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringø, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book’s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.




The Rasputin Effect: When Commensals and Symbionts Become Parasitic


Book Description

This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.




Recent Advances in Aquaculture Microbial Technology


Book Description

Recent Advances in Aquaculture Microbial Technology emphasizes various topics on microbiology related technology for aquaculture development and discusses different types of microbiological applications, thus serving as an all-inclusive reference which consolidates microbial technologies adopted in the field. The book covers the history and development of microbial technology in aquaculture as well as aquaculture microbiology, diversity and the role of microbes in aquaculture systems. In addition, it presents the beneficial microbial communities in aquaculture and varying methods employed to study bacterial association in fish, microbes and fish diseases. This resource will help improve research experiments and accomplishments in the area of aqua-culturally relevant microbial technology, making it useful for researchers and scientists in the field. - Describes the history and development of microbial technology in aquaculture - Presents scientific methods employed to study bacterial association in fish - Includes applications of microbial derived nanomaterials in disease prevention and treatment - Provides information and the use of probiotics and prebiotics in aquaculture

Bacteriocins of Lactic Acid Bacteria


Book Description

Bacteriocins of Lactic Acid Bacteria is based on the 1990 Annual Meeting of the Institute of Food Technologists held in Dallas, Texas. It describes a number of well-characterized bacteriocins and, where possible, discusses practical applications for those that have been defined thus far from the lactic acid bacteria. The book begins with an introductory overview of naturally occurring antibacterial compounds. This is followed by discussions of methods of detecting bacteriocins and biochemical procedures for extraction and purification; genetics and cellular regulation of bacteriocins; bacteriocins based on the genera of lactic acid bacteria Lactococcus, Lactobacillus, Pediococcus, and Leuconostoc, and related bacteria such as Carnobacterium and Propionibacterium; and the regulatory and political aspects for commercial use of these substances. The final chapter sets out the prognosis for the future of this dynamic area. The information contained in this book should benefit those with interest in the potential for industrial use of bacteriocins as preservative ingredients. Anyone interested in lactic acid bacteria or the biosynthesis, regulation, and mechanisms of inhibition of these proteinaceous compounds will also appreciate the material presented. These include food scientists, microbiologists, food processors and product physiologists, food toxicologists, and food and personal product regulators.
