Book Description
In the clinical microbiology laboratory, blood is a critical diagnostic sample that, in the majority of cases is sterile (or is it?). However, when microbes gain access to and multiply in the bloodstream, it can result in life-threatening illness including sepsis. Mortality rates from bloodstream infection and sepsis range from 25% to 80%, killing millions of people annually. Blood cultures are a vital technology used in the microbiology laboratory to isolate and identify microbes and predict their response to antimicrobial therapy. The Dark Art of Blood Cultures, edited by Wm. Michael Dunne, Jr., and Carey-Ann D. Burnham, surveys the entire field of blood culture technology, providing valuable information about every phase of the process, from drawing samples to culture methods to processing positive cultures. The Dark Art of Blood Cultures is organized around several major topics. History of blood culture methods. Details the timeline of blood culture methods from manual through automated and describes the technological development of the leading automated blood culture systems (Bactec, BacT/Alert, and VersaTREK). Manual and automated blood culture methods. Critiques manual and automated methods for setting up blood cultures for adult and pediatric patients. Detection of pathogens directly from blood specimens. Describes currently available CE marked and FDA-cleared commercial tests using both phenotypic and genotypic markers, including their strengths and limitations. The workflow of culturing blood. Includes best practices from specimen collection to culture system verification, processing positive cultures for microbe identification and antibiotic susceptibility determination, along with the epidemiology of positive blood cultures and the value of postmortem blood cultures. Microorganisms in the blood. Examines the concept of a blood microbiome in healthy and diseased individuals. The Dark Art of Blood Cultures is a resource that clinicians, laboratorians, lab directors, and hospital administrators will find engaging and extremely useful.

Blood Rush
Author: Jan Verplaetse
Publisher: Reaktion Books
ISBN: 1789142431
Category : History
Languages : en
Pages : 328
Book Description
As a young man, Jan Verplaetse saw a hare suspended from a meat hook, skinned and gutted. What struck him so forcefully at the time was not the animal itself, but the blood gently dripping from its mouth. His reaction prompted the start of a quest he undertakes in this book: to investigate our fascination with blood, the most vital of fluids. Blood Rush shows how, throughout history, blood has had the capacity to intoxicate us, to the point that we lose ourselves, whether in violence, through hunting, fighting, or killing, or in the vicarious thrill of watching sporting events, horror films, or video games. Are these feelings physical, or in our imagination? Where does the magic of blood come from? In his deeply researched and provocative narrative, Verplaetse moves from antiquity to the present, from magic to experimental psychology, from philosophy to religion and scientific discoveries, to demonstrate why blood at once attracts and repels us.

Antisepsis, Disinfection, and Sterilization
Author: Gerald E. McDonnell
Publisher: John Wiley & Sons
ISBN: 1555819680
Category : Medical
Languages : en
Pages : 431
Book Description
Antisepsis, Disinfection, and Sterilization: Types, Action, and Resistance, by Gerald E. McDonnell, is a detailed and accessible presentation of the current methods of microbial control. Each major category, such as physical disinfection methods, is given a chapter, in which theory, spectrum of activity, advantages, disadvantages, and modes of action of the methods are thoroughly and clearly presented. Sufficient background on the life cycles and general anatomy of microorganisms is provided so that the reader who is new to microbiology will better appreciate how physical and chemical biocides work their magic on microbes. Other topics in the book include: Evaluating the efficacy of chemical antiseptics and disinfectants, and of physical methods of microbial control and sterilization. Understanding how to choose the proper biocidal product and process for specific applications. Classic physical and chemical disinfection methods, such as heat, cold, non-ionizing radiation, acids, oxidizing agents, and metals. Newer chemical disinfectants, including, isothiazolones, micro-and nano-particles, and bacteriophages as control agents. Antisepsis of skin and wounds and the biocides that can be used as antiseptics. Classic methods of physical sterilization, such as, moist heat and dry heat sterilization, ionizing radiation, and filtration, along with newer methods, including, the use of plasma or pulsed light. Chemical sterilization methods that use ethylene oxide, formaldehyde, or a variety of other oxidizing agents. A detailed look at the modes of action of biocides in controlling microbial growth and disrupting microbial physiology. Mechanisms that microorganisms use to resist the effects of biocides. The second edition of Antisepsis, Disinfection, and Sterilization: Types, Action, and Resistance is well suited as a textbook and is outstanding as a reference book for facilities managers and application engineers in manufacturing plants, hospitals, and food production facilities. It is also essential for public health officials, healthcare professionals, and infection control practitioners.

One Health
Author: Ronald M. Atlas
Publisher: John Wiley & Sons
ISBN: 1555818439
Category : Medical
Languages : en
Pages : 332
Book Description
Emerging infectious diseases are often due to environmental disruption, which exposes microbes to a different niche that selects for new virulence traits and facilitates transmission between animals and humans. Thus, health of humans also depends upon health of animals and the environment – a concept called One Health. This book presents core concepts, compelling evidence, successful applications, and remaining challenges of One Health approaches to thwarting the threat of emerging infectious disease. Written by scientists working in the field, this book will provide a series of "stories" about how disruption of the environment and transmission from animal hosts is responsible for emerging human and animal diseases. Explains the concept of One Health and the history of the One Health paradigm shift. Traces the emergence of devastating new diseases in both animals and humans. Presents case histories of notable, new zoonoses, including West Nile virus, hantavirus, Lyme disease, SARS, and salmonella. Links several epidemic zoonoses with the environmental factors that promote them. Offers insight into the mechanisms of microbial evolution toward pathogenicity. Discusses the many causes behind the emergence of antibiotic resistance. Presents new technologies and approaches for public health disease surveillance. Offers political and bureaucratic strategies for promoting the global acceptance of One Health.

Book Description
Oral Microbiology and Immunology, Third Edition The field of oral microbiology has seen fundamental conceptual changes in recent years. Microbial communities are now seen as the fundamental etiological agent in oral diseases through their interface with host inflammatory responses. Study of structured microbial communities has increased our understanding of the roles of each member in the pathogenesis of oral diseases, principles that apply to both periodontitis and dental caries. Against this backdrop, the third edition of Oral Microbiology and Immunology has been substantially expanded and rewritten by an international team of authors and editors. Featured in the current edition are: links between oral infections and systemic disease revised and updated overview of the role of the immune system in oral infections thorough discussions of biofilm development and control more extensive illustrations and Key Points for student understanding Graduate students, researchers, and clinicians as well as students will find this new edition valuable in study and practice.
